Stability of the country should be the paramount consideration; not Red or Yellow | WITHOUT FEAR OR FAVOUR
Bersih insisted they will proceed with their gathering on 19 November and the Reds want to counter it.
It is obvious one of the main reason Yellows or Reds want to demonstrate publicly is the impact of it.
It is only then any violent or unwarranted incidents will be conspicuous and attract medias attention. Doing it in a stadium or enclosed areas will not have such impact.
Although I do support peaceful assembly as provided under the laws; violent acts or action that caused hatred and disharmony is a big no.
Hence the police should clamp down not only the Yellows but the Reds. It is proven in the past by demonstrating openly in the public, no one can guarantee a peaceful gathering especially when there is provocation.
There are many ways to skin a cat, aggressive behaviour should not be one of it.
Certain parties want to see blood; this is so when they are provoked. All it takes is a spark of fire, worst if an agent provocateur who intentionally caused it.
So it is no more a question of democratic rights or liberty; it is about stability of the country.
针对即将在11月19日举行的净选盟5.0大集会，以及近日红衫军反集会发起人拿督嘉马尤诺斯宣布将在独立广场、吉隆坡国际机场、吉隆坡第二国际机场、布城及默布草场展开机会，并将对净选盟的任何“没教养之举”以牙还牙一事，民青团署理团长杨锦成表示关注。他认为，尽管大集会可能引发暴力冲突事件，净选盟和红衫军仍坚持在公开场所举办大集会，而非在封闭场所或体育馆，当中主要的目的就是为了达到集会效果。他说只有通过在公开场所举办大集会，当中发生的暴力突发事件才会变得显著并引起各界关注，而在封闭体育馆并不会达到如此效果。
同时也是职业律师的杨锦成指出，尽管他支持2012年和平集会法令下所允许的和平集会，但却无法同意任何可能挑起仇恨和不和谐的暴力行为。他说，过往的经验指出在公开场所举行大集会或示威活动往往将引发暴力冲突事件，它无法保证和平集会中不发生挑衅和暴力冲突事件。他也举列，早前红黄双方已经在多场造势活动中气氛紧张，并发生冲突。有鉴于早前例子，尽管警方已经表示不会禁止该集会，杨锦成希望警方可以一视同仁，不只是取缔净选盟，同时也应该采取相同行动制止红衫军。
“显然，双方都希望在这次的集会中看到血流事件，以博取廉价宣传，尤其经过多番挑衅和蓄意煽动后，任何小火花都可能是暴力冲突的导火线。因此，我希望双方可以冷静并抑制情绪，避免紧张升温。红黄集会都有潜在风险引发暴力冲突事件，双方应考虑大众安全及国家利益，停止举办集会。”
杨锦成表示，任何对国家的体制感到不满的一方可以通过许多更和平以及合法的管道提出具有建设性的意见和反映不满，而不是通过街头示威等暴力宣泄的方式表达不满。这对国家的形象和健康发展是弊多于利的。

Don’t Commit To Him Unless He Treats You Like This | HuffPost
Don’t commit until you have someone who is not just your number one fan but on your team helping you get to whatever you want to be.
06/14/2017 10:46 am ET Updated Jun 22, 2017
Don’t commit to him until he really proves he wants you in his life and wants to make you a priority.
Don’t commit to him until you see him make sacrifices. The one who will do whatever you need him to when you need him to do it.
The one who will change his schedule if it makes your life easier.
Because as much as it’s the little acts like waking up and leaving you coffee before he leaves as you’re still sleeping or cooks for you and brings it to bed, there more to it than that.
Don’t commit to him until you’ve seen every side of him and know that you still love him. A good mood or bad mood. Drunk. Angry. Sad. Frustrated when his team loses. In every physical form, someone can be. When he has morning breath or is dressed to a T.
And make sure you can show him every side of you.
Don’t commit to him until you know he’s got your back supporting you, encouraging you, making you better and making you want to achieve more. The one who isn’t afraid to tell you when you’re settling in life or not standing up for yourself or not doing what you need to do. But then goes and holds your hand as you do it. Don’t commit until you have someone who is not just your number one fan but on your team helping you get to whatever you want to be. The one who knows when to lift you when you’ve fallen but also knows when to stand back and just watch in awe.
Don’t commit to him until you know his word is gold and flaking out on you or changing plans is the last thing he’d ever do.
Don’t commit to him until you see him apologize when he’s wrong and does everything to make it right.
The one who actually wants to know how your day is. The one who picks up the phone and calls. The one you lose track of time talking to because you’re lost in each other. Don’t commit until you know he loves you and isn’t afraid to say it even if it’s first.
Don’t commit until he enters your life upping and the previous standard you might have had.
The one who looks at challenges in relationships as something you can overcome together. Don’t commit until you know he wants you in your future and when you look in his eyes you both forget and forgive yourself for the past.

First, sorry about the ‘maters in the pictures. It’s that time o’ year in the cake chick household.
Secondly- so many jokes left unjoked. It was tough. Tryin’ to keep it PG on the blog so I left out stuff about white powder and the funny of the week at work concerning “nice box.” Just know that I know and that I wish I coulda but I can’t. It’s for our own good. I hope. I really hate to waste a good joke….

& just one more: the best laid plans, part 2
Posted by Daniele at 12:06 AM
meredith kraine said...
Thank you for these thoughts, Daniele. I, too, struggle with the need to be in control. I feel physically sick when I enter situations where I feel out of control. Thank you for reminding me that the most stability and peace I can find in life is to put my whole trust in the One who made me, the One who is in control of the entire universe, in God my Father and Jesus Christ my Savior. Blessings to you, Daniele!
I so appreciate, admire, and adore your honesty about pregnancy. It's refreshing amidst so many other "cotton candy" tales I hear! And the control thing? I can't relate to that at all ;)

Burrowers, Books & Balderdash: Delusional Thursday - Doomed
And there is doom metal, a dark and slow sub-genre of heavy metal. Some good bands are Candlemass, Katatonia, My Dying Bride and Anathema >:)
Funnily enough, as I was leaving my friend's house a few minutes ago, she was babbling on about being doomed because of... errrrrm... something or other, I kinda forget 'cause I'm stuffed full of food and we had lots of wine. :-)

Coalition, Hindered By the Syrian Regime, Kills Islamic State Leaders
By Kyle Orton (@KyleWOrton) on 19 December 2017
Maghaweer al-Thawra fighters next to American forces at at-Tanf. (Hammurabi’s Justice News/AP)
The U.S.-led Coalition against the Islamic State (IS) has killed several more leaders of the terrorist group, but continues to find that the campaign is hindered by the incompetence and/or complicity of the regime of Bashar al-Asad and his supporters in Iran and Russia. Continue reading →

A Year In, Trump’s Syria Policy Looks A Lot Like Obama’s
By Kyle Orton (@KyleWOrton) on 18 December 2017
Nearly a year into Donald Trump’s administration, the president has followed the track laid down by his predecessors in Syria, accelerating it in some cases, and reinforcing the negative trends of Barack Obama’s defective policy that will undo even apparent successes, like the destruction of the Islamic State’s (ISIS) “caliphate”.

Some Other Mountain : Empty Benches
I started to draft this one on Friday, ready for Shadow Shot Sunday like I sometimes do. Saturday morning was gorgeous weather wise so up bright and early and helping Other Half clear some brash down at the Mill. An errant falling branch whipped across my face. A couple of hours later, was in dire agony and a trip to the local A&E. I had apparently scarred my corneal quite badly. No lasting damage though, thank goodness, but a bit of a sore week ahead she said. Came out of the hospital, went to start the car - not a dickey bird, dead as a dodo again. We waited a couple of hours and then tried the ignition again. Nothing! Rang the Road Rescue. Sunny weather, busy Saturday - they said they'd be with us in three hours, but in all fairness it was not quite as long as that. Car still wouldn't start. After about an hour of the Man that Can poking about it still wouldn't and didn't start and we were unceremoniously towed home about 7 pm. But in all fairness, I couldn't get over how how kind and helpful the people around us were. If any of you happen to read this, thank you so much for all your kindness.

Jees Molly, you should have stayed in bed.
Sometimes we can get cynical about people. However, when we find ourselves in trouble and strangers come to give us a hand and we are so grateful for their kindness, the world seems like a better place.

Menu laws too much to digest - tribunedigital-chicagotribune
June 22, 2008|By Steve Chapman, a member of the Tribune's editorial board
But the entire effort rests on assumptions that are unexamined and unfounded. The first is that consumers place a high value on the information being mandated. Actually, most of it is already accessible (online, among other ways) to anyone who is interested. In many places, it is available on-site, on tray liners or in pamphlets.
Americans may say they would also like to see dietary information on menus. But providing it costs money in a fiercely competitive industry. If patrons really wanted such disclosures, no law would be needed. Restaurants, eager to attract customers, would already be providing the numbers -- just as they strive to offer other things that bring in business.

System and method for turbine engine clearance control with rub detection
US 8177474 B2
A method of detecting rubs during operation of a turbomachine comprising at least one rotating object having a tip and a shelf is provided. The method includes generating signals representative of a sensed parameter and processing the signals to generate height versus time data for the tip. The height of the tip corresponds to the distance between the tip and the shelf. The method further includes monitoring the height versus time data, in order to determine whether a change in the height data exceeds a threshold value, and detecting a rub of the rotating object(s) on a second object, when the change in the height data exceeds the threshold value. A rub detection system for a turbomachine and a turbine engine system with rub detection are also provided.
1. A method of detecting rubs during operation of a turbomachine comprising at least one rotating object having a tip and a shelf, the method comprising:
generating a plurality of signals representative of a sensed parameter;
processing the signals to generate a plurality of height versus time data for the tip, wherein a height of the tip corresponds to a distance between the tip and the shelf;
monitoring the height versus time data in order to determine whether a change in the height data exceeds a threshold value; and
detecting a rub of the at least one rotating object on a second object, when the change in the height data exceeds the threshold value.
2. The method of claim 1, further comprising adjusting the clearance between the at least one rotating object and the second object based on the rub detection.
3. The method of claim 1, further comprising displaying one or more health indicators for the at least one rotating object that include information about the rub detection.
4. The method of claim 1, further comprising controlling one or more engine parameters based at least in part on the rub detection.
5. The method of claim 1, wherein the turbomachine comprises a plurality of rotating objects, and wherein the generating, processing, monitoring and rub detection steps are performed for each of the rotating objects.
6. The method of claim 5, wherein each of the rotating objects comprises a turbine blade, and wherein the height data corresponds to squealer tip height values.
7. The method of claim 6, wherein the threshold value is adaptive and varies as a function of a number of blades over which a rub has occurred, such that a threshold value is higher where the squealer tip height of only one of the blades changes and conversely is lower where the squealer tip height of at least two adjacent blades changes over a defined time period.
8. The method of claim 7, wherein the threshold value further varies as an inverse function of the signal-to-noise ratio (SNR).
9. The method of claim 6, wherein each of the signals comprises a signal waveform, and wherein the processing comprises performing an N-dimensional optimization operation on the signal waveform, where N is the number of data points selected from the signal waveform.
10. The method of claim 9, wherein a calibration function is defined as:
F ( δ , h , g c ) = g c [ C _ 1 ( r tip 1 , δ + d p , h ) C _ 1 ( r sh 1 , δ + d p , h ) ]
wherein performing the N-dimensional optimization operation comprises simultaneously solving an equation for h and δ:
[ Vtip 1 Vsh 1 ] = F ( δ , h , g c )
where gc is a system gain value, h is the squealer tip height, δ is a true clearance value, dp is an offset value, C1 is a probe response, Vtip1 is a tip-to-base voltage, Vsh1 is a shelf-to-base voltage, and rtip1 and rsh1 are relative circumferential positions for the squealer tip and the blade shelf.
11. The method of claim 9, wherein a calibration function is defined as:
F ( δ , h , g c ) = g c [ C _ 1 ( r i , δ + d p , h ) C _ 1 ( r j , δ + d p , h ) ]
[ Vi Vj ] = F ( δ , h , g c )
wherein gc is a system gain value, h is the squealer tip height, δ is a true clearance value, dp is an offset value, C1 is a probe response, wherein ri and rj are two relative circumferential blade positions, and wherein Vi and Vj are corresponding voltage values.
12. The method of claim 1, wherein the sensed parameter comprises a capacitance.
13. A rub detection system for a turbomachine comprising at least one rotating object having a tip and a shelf, the system comprising:
at least one sensor configured to generate a plurality of signals representative of a sensed parameter corresponding to the at least one rotating object at a plurality of times;
evaluate the signals to generate a plurality of height versus time data for the tip, wherein a height of the tip corresponds to a distance between the tip and the shelf,
monitor the height versus time data in order to determine whether a change in the height data exceeds a threshold value, and
output a rub detection signal when the change in the height data exceeds the threshold value; and
a controller configured to receive the rub detection signal.
14. The rub detection system of claim 13, wherein the controller is further configured to adjust the clearance between the at least one rotating object and a second object in response to the rub detection signal.
15. The rub detection system of claim 13, wherein the controller is further configured to control one or more engine parameters based at least in part on the rub detection signal.
16. The rub detection system of claim 13 further comprising a health monitoring unit configured to receive the rub detection signal and display one or more health indicators for the at least one rotating object that includes rub detection information.
17. The rub detection system of claim 13, wherein the turbomachine comprises a plurality of rotating objects,
wherein the at least one sensor is configured to generate signals corresponding to each of the rotating objects, and
wherein the processor is configured to generate the height versus time data for each of the tips of the rotating objects and to perform the monitoring for each of the rotating objects.
18. The rub detection system of claim 17, wherein each of the rotating objects comprises a turbine blade, and wherein the height data correspond to squealer tip height values, and

The invention relates generally to active clearance control for turbomachinery and, more particularly, to rub detection for turbine engines.
In a turbine engine or other such rotating machinery, the clearance (gap) between the blades and the shroud is an important design and operational parameter of the engine. For aircraft engines, during different parts of the flight cycle, various thermal and mechanical effects lead to the gap changing. In some of these instances, that change is not uniform across the shroud or around the circumference of the engine.
Modern engines incorporate active clearance control systems to minimize these changes. Clearances are traditionally controlled using an analytic model with a built in safety margin to avoid rubs. Such models are necessarily very conservative, resulting in a less than optimal demand clearance.
In systems employing a clearance sensor, eccentricities in the clearance can result in the sensor measuring a positive clearance number, even when a rub has occurred elsewhere around the engine. Thus, for a system in which an active clearance control strategy is employed, this would result in the control driving the clearance to smaller values, even in the case where a pinch point exists and a rub has occurred. If this situation occurs, then the clearance control system runs the risk of rubbing away a substantial portion of the blade squealer tips to the point that subsequent closure of the clearance becomes impossible. However, for systems in which a clearance/displacement sensor is employed, it would be possible to do a rudimentary rub avoidance, through the use of a safety margin, in conjunction with the clearance measurement system, in order to account for some rotor or shroud eccentricities. This approach, however, lacks the desired sensitivity and precision needed for accurate control of clearances.
It would therefore be desirable to provide a clearance control method and system using clearance sensor data for rub detection. It would further be desirable for the clearance control method and system to provide enhanced sensitivity and accuracy for rub detection, so that active clearance control strategies could be beneficially employed.
Briefly, one aspect of the present invention resides in a method of detecting rubs during operation of a turbomachine comprising at least one rotating object having a tip and a shelf. The method includes generating signals representative of a sensed parameter and processing the signals to generate height versus time data for the tip. The height of the tip corresponds to the distance between the tip and the shelf. The method further includes monitoring the height versus time data in order to determine whether a change in the height data exceeds a threshold value and detecting a rub of the rotating object(s) on a second object, when the change in the height data exceeds the threshold value.

A rub detection system 50 embodiment of the invention is described with reference to FIGS. 1-7. The turbomachine 10 includes at least one rotating object 20 having a tip 22 and a shelf 24. Nonlimiting examples of turbomachines include aircraft engines, power generation turbines, turbochargers for locomotive engines, compressors and oil and gas pumping units. In one example, the turbomachine is an aircraft engine or a turbine stage thereof, and the rotating object 20 is a turbine blade 20. For example, the turbomachine is a high-pressure turbine stage of a turbine engine, and the rotating object is a high pressure turbine blade. FIG. 1 schematically depicts an example “squealer tip” 22 of an example turbine blade. As indicated in FIG. 1, the tip 22 extends from the blade shelf 24 and the distance between the tip 22 and the shelf 24 is the tip or squealer height h. The dimensions given in the figures and text are merely examples, and the invention is not limited to any specific part dimensions or part design.
As indicated for example in FIG. 3, the rub detection system 50 includes at least one sensor 52 configured to generate signals representative of a sensed parameter corresponding to the rotating object(s) 20 at a plurality of times. The system 50 further includes a processor 60 configured to evaluate the signals to generate height h versus time data for the tip 22. As noted above with reference to FIG. 1, the height h of the tip 22 corresponds to the distance between the tip 22 and the shelf 24. The processor 60 is further configured to monitor the height h versus time data in order to determine whether a change in the height data exceeds a threshold value hthreshold, and to output a rub detection signal when the change in the height data exceeds the threshold value hthreshold. The rub detection system further includes a controller 70 configured to receive the rub detection signal. For the illustrated example, the controller 70 is a FADEC (full authority digital engine control system). In other non-limiting examples, the controller 70 is an (engine or blade) health monitoring system.
In one embodiment, the controller 70 is further configured to adjust the clearance between the rotating object(s) and a second object 30 in response to the control signal. More generally, for particular embodiments, the controller 70 is configured to adjust one or more engine parameters based at least in part on the rub detection. Non-limiting examples of engine parameters include bypass air bleed or compressor air bleed flow rates directed to impinge on the second object 30 to control its thermal growth, an electrical signal to mechanically adjust the radial position of shrouds mounted on the second object 30, or air pressures that may be used to mechanically adjust the position of the second object 30. In another embodiment, the rub detection system 50 further includes a health monitoring unit 90, which is configured to receive the rub detection signal and display one or more health indicators for the rotating object(s) 20 that include rub detection information.
According to particular embodiments, the sensor(s) 52 comprises a capacitive sensor, and the sensed parameter comprises capacitance. The specific sensor configuration is not the subject of the present invention and will not be described in detail. It should be noted that the probe arrangement in FIG. 1, which shows a single probe with two offset probe tips 54, 56 is merely one possible arrangement. More generally, two or more separate single-head probes could be used, and the probes need not be co-located but rather could be spatially separated. In addition, the arrangement of FIG. 1 could be modified to employ a single, self-calibrated probe, as well. Specific arrangements of capacitive sensors are discussed for example, in commonly assigned US Published Patent Application US20060132147A1, Mahadevan Balasubramaniam et al, “SYSTEM AND METHOD FOR MEASURING CLEARANCE BETWEEN TWO OBJECTS” and in U.S. Pat. No. 7,215,129, Emad Andarawis et al., “Multitip clearance measurement system and method of operation.” FIG. 4 shows sample waveforms 80, 81, 82 for a squealer tip 22 and shelf 24 taken using a capacitive probe. The three waveforms 80, 81, 82 were obtained at a 5 mil, a 15 mil and a 25 mil offset.
In a number of embodiments, the turbomachine 10 comprises a plurality of rotating objects 20. For example, the turbine engine 10 of FIG. 2 includes a number of turbine blades 20, and the stationary object 30 is a turbine case 30. For these embodiments, the sensor(s) 52 is (are) configured to generate signals corresponding to each of the rotating objects 20. Similarly, the processor 60 is configured to generate the height h versus time data for each of the tips of the rotating objects and to perform the monitoring for each of the rotating objects. For the embodiment in which the controller 70 is further configured to control the clearance in response to the rub detection signal(s), the controller 70 is configured to collectively adjust the clearance between the rotating objects 20 and the second object 30 in response to the control signal. For the example shown in FIG. 3, the controller 70 adjusts the clearance by sending one or more control signals to a (thermal) actuator 72, which in turn adjusts the clearance between the blades 20 and the casing 30 by thermal actuation. This is merely one example, and other types of actuators or adjustment schemes may be used to adjust the clearance.
For the sample sensor arrangement shown in FIG. 2, there are three sensors 52 used to monitor the clearance and tip height during operation of the turbomachine 10. In other applications, there may be 1, 2, 4 or other numbers of sensors 52 used to monitor the clearance and tip height.
As discussed above and as illustrated, for example, by FIG. 2, in particular embodiments, each of the rotating objects 20 comprises a turbine blade 20, and the height h data correspond to squealer tip height h values. According to more particular embodiments, the threshold value hthreshold is adaptive and varies as a function of the number of blades 20 over which a rub has occurred, such that the threshold value hthreshold is higher where the squealer tip height h of only one of the blades 20 changes and conversely is lower where the squealer tip height h of at least two adjacent blades 20 changes over a defined time period. In many applications, the rotation speed is high (for example 12000-40000 rpm, depending on the application), and the data can be averaged over a number of revolutions, for example 1000 or 10,000, in a short time period, such that a fast response time can be maintained. It should further be noted that the 1000 and 10,000 blade averages indicated in FIG. 9 are merely examples, and in general any practical blade average can be used. Ideally, the average would be taken over the minimum number of revolutions to achieve a desired signal to noise ratio, while maintaining a fast response time. If the squealer tip height h of several adjacent blades 10 changes over 1000 (or 10,000 etc.) revolutions, it is more likely that a rub has occurred, than if the squealer tip height h of only one blade 20 (or of isolated blades 20) has occurred during the same time period. Accordingly, the threshold value hthreshold at which a rub will be said to have occurred (such that corrective action may be taken to adjust the clearance between the blades 20 and the turbine casing 30) adapts to the number of adjacent blades experiencing a change in height h. Beneficially, this adaptive threshold increases sensitivity, while maintaining an acceptable false positive probability.
Sensitivity is further enhanced by varying the threshold value hthreshold as an inverse function of the signal-to-noise ratio (SNR). Namely, the threshold value increases as the SNR decreases (poor SNR) and decreases as the SNR increases (good SNR). This adaptive threshold technique helps to avoid false positives when the SNR is poor and provides high sensitivity, and thus fast rub detection, in high SNR environments.
For particular embodiments, the at least one signal obtained using sensor(s) 52 comprises a signal waveform 80, 81, 82, and the processor 60 is configured to perform an N-dimensional optimization operation on the signal waveform, where N is the number of data points selected from the signal waveform. As noted above, FIG. 4 shows three sample waveforms 80, 81, 82 taken using a capacitive sensor 52 for a blade tip 22. With a capacitance sensor what is measured is the capacitance seen by the sensor tip, with the blade present, relative to the capacitance seen by the sensor tip, when the blade has rotated past the sensor. These capacitance measurements are a function of circumferential, as well as radial distance between the sensor and the blade, plus significant blade dimensions, such as squealer height and, to a lesser extent, the wear on the squealer tips. A capacitive sensor 52 is characterized by the normalized relative capacitance:
C k(r,d,h)=C k(r,d,h)/c refk, and
is further characterized by the reference capacitance:
c refk =c k(r tipk,δref +d p ,h ref),
where the channel number, k=1,2, and “d” is the radial distance between the sensor and the blade tip, as indicated in FIG. 1. Example relative capacitance functions are shown in FIGS. 5 and 6. FIG. 5 shows relative capacitance functions for a fixed value of h (h=0.04), for different values of δ, ranging from 0.01-0.06. FIG. 6 shows relative capacitance functions for a fixed value of δ (δ=0.01), for different values of h (0.02, 0.04 and 0.06). FIG. 7 illustrates relative capacitance functions for a forward probe tip position and for a setback probe tip position. FIG. 1 indicates a forward probe tip position and a setback probe tip position, with an example setback of 0.015 inches. This setback is merely an example, and the invention is not limited to specific probe positions or setbacks. As discussed above, the probe arrangement in FIG. 1 is merely one possible arrangement. More generally, two or more separate single-head probes could be used, and the probes need not be co-located but rather could be spatially separated. In addition, the arrangement of FIG. 1 could be modified to employ a single, self-calibrated probe, as well.
According to a more particular embodiment, a calibration function F for a single sensor tip (k=1) is defined as:
and the N-dimensional optimization operation is performed by simultaneously solving the following equation for h and δ:
where gc is a system gain value, h is the squealer tip height, δ is a true clearance value, dp is an offset value, C1 is a probe response, Vtip1 is a tip-to-base voltage, Vsh1 is a shelf-to-base voltage, and rtip1 and rsh1 are relative circumferential positions for the squealer tip 22 and the blade shelf 24. This optimization can be generalized by replacing rtip1 and rsh1 by ri and rj, which are two relative circumferential blade positions, and by replacing Vtip1 and Vsh1 with the corresponding voltage values Vi and Vj. In other words, the solution of the optimization problem is not limited to the specific points rtip1 and rsh1 (and corresponding voltage values Vtip1 and Vsh1) but rather can be solved using two or more points ri and rj (and the corresponding two or more voltage values Vi and Vj).
A method of detecting rubs during operation of a turbomachine 10 is described with reference to FIGS. 8, 9 and 11. As discussed above with reference to FIG. 1, the turbomachine 10 includes at least one rotating object 20 having a tip 22 and a shelf 24. FIG. 8 is a flow chart illustrating a clearance control method embodiment of the invention. As indicated in FIG. 8, the method 100 includes at step 110 generating signals representative of a sensed parameter. In particular embodiments, the sensed parameter is capacitance. The method further includes at step 120 processing the signals to generate height versus time data for the tip, where a height h of the tip corresponds to a distance between the tip and the shelf, as discussed above with reference to FIG. 1. The method further includes at step 130 monitoring the height h versus time data in order to determine whether a change in the height h data exceeds a threshold value hthreshold. The method further includes at step 140 detecting a rub of the rotating object(s) on a second object 30, when the change in the height data exceeds the threshold value hthreshold.
As indicated for example in FIG. 11, the method further optionally includes at step 142 adjusting the clearance between the rotating object(s) 20 and the second object 30 based on the rub detection. At step 144, the method optionally includes displaying one or more health indicators for the rotating object(s) 20 that include information about the rub detection. At step 146, the method optionally includes controlling one or more engine parameters based at least in part on the rub detection. As noted above, non-limiting examples of engine parameters include case cooling or heating air flows (for example, valve positions for the cool and hot air that impinges on the stator) for controlling thermal growth, electrical signals to mechanically adjust static shroud positions, or cavity pressures to mechanically position the static member 30.
As discussed above with reference to FIG. 2, for a number of embodiments, the turbomachine 10 comprises a plurality of rotating objects 20. For example, the turbine engine 10 of FIG. 2 includes a number of turbine blades 20, and the stationary object 30 is a turbine case 30. For these embodiments, the generating, processing, monitoring and rub detection steps 110, 120, 130, 140 are performed for each of the rotating objects 20.
As discussed above and as illustrated, for example, by FIG. 2, in particular embodiments, each of the rotating objects 20 comprises a turbine blade 20, and the height h data correspond to squealer tip height h values. According to more particular embodiments, the threshold value hthreshold is adaptive and varies as a function of the number of blades 20 over which a rub has occurred, such that the threshold value hthreshold is higher where the squealer tip height h of only one of the blades 20 changes and conversely is lower where the squealer tip height h of at least two adjacent blades 20 changes over a defined time period. Beneficially, this adaptive threshold increases sensitivity, while maintaining an acceptable false positive probability.
As discussed above, sensitivity is further enhanced by varying the threshold value hthreshold as an inverse function of the signal-to-noise ratio (SNR). Namely, the threshold value increases as the SNR decreases (poor SNR) and decreases as the SNR increases (good SNR). This adaptive threshold technique helps to avoid false positives when the SNR is poor and provides high sensitivity, and thus fast rub detection, in high SNR environments.
FIG. 9 is a logic flow chart for a closed loop, turbine active clearance control application of the invention. As noted above, one or more sensors 52 may be used to monitor the rotating parts 20. In the illustrated example, there are two sensors 52 (Probes A and B). For the illustrated example, the probe signals are digitized. Next, the tip height for each blade is calculated using the digitized signals. For the illustrated example, an initial average tip height for the first 1000 successive revolutions with a clearance of less than 0.050 inches is calculated. It should be noted that this example is illustrative and non-limiting. For the illustrated example, a rub is defined when a 1000 revolution moving average tip height is less than the initial average 1000 revolution tip height for five (5) or more blades. Next, it is determined whether a rub is detected. If yes, then a change to the FADEC settings is indicated, in order to open (or increase) the clearance. Upon clearance (removal) of a rub, it is desirable to delay closing (reducing) the clearance, in order to prevent the rub from starting again. Thus, it is next determined whether a rub is indicated in 10,000 revolutions. If no rub is indicated, then no change to the FADEC settings is indicated. In this example, the 10,000 revolution limit serves as a pause to avoid re-initiating the rub. If the rub has been cleared for 10,000 revolutions, then the controller 70 begins to increment back to the nominal FADEC schedule. In addition to the logic operations shown in FIG. 9, additional calculations and logic steps may then be performed at (A)-(E) to further determine whether to modify the FADEC settings, and if so, what the modifications should be.
The processing step 120 can be performed using a number of techniques. For particular embodiments, the at least one signal comprises a signal waveform 80, 81, 82 as indicated for example in FIG. 4, and the processing step 120 comprises performing an N-dimensional optimization operation on the signal waveform, where N is the number of data points selected from the signal waveform. According to a more particular embodiment, a calibration function F is defined as:
as discussed above. This optimization can be generalized by replacing rtip1 and rsh1 by ri and rj, which are two relative circumferential blade positions, and by replacing Vtip1 and Vsh1 with the corresponding voltage values Vi and Vj. In other words, the solution of the optimization problem is not limited to the specific points rtip1 and rsh1 (and corresponding voltage values Vtip1 and Vsh1) but rather can be solved using two points ri and rj (and the corresponding voltage values Vi and Vj).
A turbine engine system 150 with rub detection is described with reference to FIG. 10. As shown, for example, in FIG. 10, the turbine engine system 150 includes at least one rotating component 20 having a tip 22 and a shelf 24. Example rotating components 20 are discussed above with reference to FIG. 1. For the illustrated embodiment, the turbine engine system 150 includes a plurality of rotating components 20. The turbine engine system 150 further includes a stationary component 30 spaced apart from the rotating component(s) 20. At least one sensor 52 is configured to generate signals representative of a sensed parameter corresponding to the rotating object(s) at a plurality of times. As noted above, in particular embodiments, the sensor 52(s) comprises a capacitive sensor, and the sensed parameter is capacitance. As indicated in FIG. 10, the turbine engine system 150 further includes a processor 60 configured to evaluate the signals to generate height h versus time data for the tip, monitor the height versus time data in order to determine whether a change in the height data exceeds a threshold value hthreshold, and output a rub detection signal when the change in the height data exceeds the threshold value. As discussed above with reference to FIG. 1, the height h of the tip 22 corresponds to the distance between the tip 22 and the shelf 24. The turbine engine system 150 further includes a controller 70 configured to receive the rub detection signal. In particular embodiments, the controller 70 is further configured to adjust the clearance between the rotating object(s) 20 and a second object 30 in response to the control signal. One non-limiting example of the controller 70 is a FADEC. More generally, for certain embodiments, the controller is configured to control one or more engine parameters based at least in part on the rub detection signal. Sample logic for a control scheme using rub detection is discussed above with reference to FIG. 9. For the illustrated example, the turbine engine system 150 further includes an actuator 72, for example a thermal actuator, which receives the control signal from controller 70 and adjusts the clearance between the turbine case 30 and the turbine blades 20 in response to the control signal. In addition, for the illustrated embodiment, the turbine engine system 150 further includes a health monitoring unit for displaying one or more health indicators for the rotating part(s) 20, where the health indicators include information related to rub detection. Various other features, embodiments and implementations of turbine engine system 150 are discussed in detail above with reference to the rub detection system and method embodiments of the invention.
The above-described embodiments use spatially sensitive clearance sensor(s) that is (are) sensitive to blade shapes and then track the blade shapes as a function of time. Rub occurrence is thus determined based on blade shape changes, not just on clearance measurements. Beneficially, the invention is capable of detecting rubs that occur at points away from the location of the installed clearance sensor by means of tracking blade shape features and flagging changes that occur over time. In addition, the adaptive determination of rub detection thresholds based on SNR and measurement conditions enhances sensitivity. As a result, the above-described embodiments allow for the operation of a closed loop active clearance control system at a significantly reduced gap size. Since rubs are detected even when they occur away from the sensor location, the clearance can be kept small, thus improving the energy efficiency of the engine. In addition, since rubs are detected and flagged quickly, blade wear due to rubs can greatly be reduced. The sensor's ability to track squealer tip changes over time also enables blade health checking, and can trigger blade servicing at optimum times instead of preset intervals.

Good day to all of you! I've been busy myself lately - but I'm gonna update my blog as I can. So, today's blogpost is my review of Rimmel's Match Perfect Foundation. I rarely use foundation because most of the time I don't feel comfortable wearing it.
Buona giornata a tutte voi! Ultimamente sono impegnata - ma provo ad aggiornare il mio blog finché posso. Quindi, il post di oggi è la mia recensione su Match Perfect Foundation della Rimmel. Uso raramente il fondotinta perché non lo trovo gradevole nella maggior parte del tempo quando lo indosso.
