it was not until the submarine 's trim equalized that captain 3d rank yudin and warrant officer chernikov were able to drag warrant officer slyusarenko into the chamber .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

before the hatch was closed we heard noise recalling boiling water -- obviously air was escaping from the sinking submarine . ''


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

as we can see from this , air entered the chamber from the submarine at the moment the lower hatch of the rescue chamber was being battened down , creating an elevated pressure within it .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

in addition the rescue chamber was `` tethered '' by this hose to the submarine 's pressure hull .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

this meant that the rescue chamber could surface only after the submarine compartments were completely flooded and the pressure within it was equalized with outside pressure , on the condition that the chamber 's buoyancy would be sufficient to break the air hose .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

the sequence of the personnel 's actions following separation of the rescue chamber from the submarine was presented somewhat differently in warrant officer slyusarenko 's explanatory report .

we can not be fully certain that the personnel had carried out all of the operation to separate the rescue chamber from the submarine correctly , even with the help of the posted instructions .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

with the lower conning tower hatch open , the crew could not have done anything to separate the rescue chamber from the submarine until pressure within the submarine equalized with the outside water pressure .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

opening of the fore chamber flooding valve produced no results because the lower conning tower hatch was open , and outside pressure continued to press the rescue chamber against the coaming of the submarine 's pressure hull with great force .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

the nature of the damage and the positions of the damaged structures clearly indicate that this damage occurred after the submarine struck bottom .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

of all the possible causes of damage to the upper cover of the entry hatch -lrb- explosion of ammunition , explosion of gases released from the storage battery or torpedoes , a shock wave caused by elastic deformations of the pressure hull as the submarine struck bottom , and hydraulic shock occurring with rupture of the pressure tanks -rrb- , hydraulic shock is the most probable cause .

when compartments 6 and 7 are flooded at the same time that main ballast tank no. 10 is flooded , the submarine loses 50 percent of its buoyancy reserve at the stern .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

this is not counting the unblown tank no. 5 and the flooded starboard tank no 7 . elementary logic tells us that no submarine can remain afloat with such loss of buoyancy and with such an upsetting moment .

the leadership of submarine formations is responsible for such development .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

there is no need to bring up the fact that not a single submarine of the navy has an integrated system for forecasting possible development of events in extreme situations on the basis of objective data .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

no submarines of the navy have a system for controlling the airtightness of compartments from the control room -lrb- with the exception of a certain class of submarine with a limited number of personnel -rrb- .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

development of such systems for manned compartments is not foreseen in the navy 's requirements on submarine design .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

introduction of such a system into a submarine would be equivalent to complicating the design , increasing the weight and size characteristics of the equipment , and reducing its reliability .

none of the `` design peculiarities '' could have caused the accident and the demise of the submarine .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

the `` consequences '' indicated by the authors do not reflect the actual circumstances of the accident , and they are directed at justifying the inactivity of the submarine 's leadership in ship damage control , and at covering up the mistakes it made .


Question: what nuclear-powered russian submarine sank in the norwegian sea on april 7 , 1989 ?

but there 's one thing that raises questions : the deadline for fulfilling measures to organize training centers and to improve submarine basing and technical maintenance conditions , and measures in the social sphere , has been extended to the year 2000 , and most of the funds for scientific research and experimental design work -lrb- up to 75 percent -rrb- are to be spent on projects having nothing to do with the fire safety of submarines or their survivability , or with designing individual protective and rescue equipment for submariners .
