what is the top speed of thrust ssc
1,228 km/h
title: Supersonic transport text: high jet velocities used during take-off, and even more importantly flying over communities near the airport. SST engines need a fairly high specific thrust (net thrust/airflow) during supersonic cruise, to minimize engine cross-sectional area and, thereby, nacelle drag. Unfortunately this implies a high jet velocity, which makes the engines noisy which causes problems particularly at low speeds/altitudes and at take-off. Therefore, a future SST might well benefit from a variable cycle engine, where the specific thrust (and therefore jet velocity and noise) is low at take-off, but is forced high during supersonic cruise. Transition between the two modes would occur title: SSC Aero text: Records" on October 9, 2007. SSC is currently one of only 26 automobile manufacturers in history to have held the record. SSC also applied to Guinness for the world record for the highest power for an emissions-legal production automobile. Its record was broken on July 4, 2010 by the Bugatti Veyron Super Sport, which reached a certified top speed of . SSC Aero The SSC Ultimate Aero is a mid-engined sports car that was produced by SSC North America (formerly known as Shelby SuperCars) from 2006 until 2013. The SSC Ultimate Aero held the title of the fastest production car title: Supersonic transport text: Supersonic transport A supersonic transport (SST) is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound. To date, the only SSTs to see regular service have been Concorde and the Tupolev Tu-144. The last passenger flight of the Tu-144 was in June 1978 and it was last flown in 1999 by NASA. Concorde's last commercial flight was in October 2003, with a November 26, 2003 ferry flight being its last airborne operation. Following the permanent cessation of flying by Concorde, there are no remaining SSTs in commercial service. Several companies have each proposed title: Space Shuttle Solid Rocket Booster text: by the onboard computers at T minus 6.6 seconds (staggered start engine three, engine two, engine one all approximately within 0.25 of a second), and the sequence monitors the thrust buildup of each engine. All three SSMEs must reach the required 90% thrust within three seconds; otherwise, an orderly shutdown is commanded and safing functions are initiated. Normal thrust buildup to the required 90% thrust level will result in the SSMEs being commanded to the lift off position at T minus three seconds as well as the fire 1 command being issued to arm the SRBs. At T minus three title: SSC Aero text: which is a spoiler that rises up to when the brake is pressed. This updated model reached a top speed of in a test, according to SSC. In 2009, SSC announced that they would be commencing production of the Ultimate Aero EV, an electrically-powered version of the Ultimate Aero. This car featured twin electric motors, claimed to be capable of producing , and of torque, which was transmitted through a three-speed automatic transmission. SSC claimed that the car would be able to accelerate from in 2.5 seconds, and reach a top speed of . However, the car never entered production.
