Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration. Thrust reverser systems are featured on many jet aircraft to help slow down just after touch-down, reducing wear on the brakes and enabling shorter landing ...
The reverse-thrust ratio (ratio of backward engine thrust to forward reverse thrust) can be as high as 84%. [6] However, this result is obtained with a cowl to attach air flow in a 7° angle and a large enough "target" (deflector door) installed. A reverse-thrust ratio of 55% can be reached on a simple target without the cowl. [7]
Originally known as the S-37, Sukhoi redesignated its advanced test aircraft as the Su-47 in 2002. Officially nicknamed Berkut (Russian: Беркут) (the Russian word for the golden eagle), the Su-47 was originally built as Russia's principal testbed for composite materials and sophisticated fly-by-wire control systems, as well as new airframe technologies.
Five of the planes under construction at the end of the War were to be completed as two-seat trainers. [5] Other follow-on versions proposed included a reconnaissance aircraft and a fighter armed with two 30 mm Type 5 cannons with 50 rounds per gun.
The Republic XF-84H "Thunderscreech" is an American experimental turboprop aircraft derived from the F-84F Thunderstreak.Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the ...
Powerback is used by aircraft to move backwards on the ground using the power of their engines in reverse thrust operation. [1] Civil and general aviation aircraft equipped with reverse thrust are technically or theoretically able to use powerbacks as a means of "backing up" but such operation is prohibited or strongly discouraged by aircraft manufacturers as well as airport safety regulations ...

By April 2011, 18 aircraft (nine two-seater aircraft and nine single-seaters) had been delivered. [214] While the establishment of a Gripen Fighter Weapon School at Overberg Air Force Base in South Africa had been under consideration, in July 2013 Saab ruled out the option due to a lack of local support for the initiative; Thailand is an ...
