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 Herbst maneuver (also known as a J-turn [1] [2]) is an air combat maneuver that uses post-stall technology such as thrust vectoring and advanced flight controls to achieve high angles of attack. [3] The Herbst maneuver allows an aircraft to quickly reverse direction using a combination of high angle-of-attack and rolling.
Video of a target-type thrust reverser in operation. Target-type thrust reversal (also called bucket thrust reversal or clamshell thrust reversal [1]) is a deceleration method when an aircraft lands. Like other types of thrust reversals, it temporarily diverts the engine exhaust forward to provide deceleration. This type of thrust-reverser is ...
The Contrafan was designed to power the four-engine Boeing 747 at a cruise speed of Mach 0.9. Like the General Electric Unducted Fan (UDF), the RB529 would have direct-drive contra-rotating fans in pusher configuration, and it would have variable pitch fan blades that were capable of reverse thrust.
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 ...

The JF-17 was designed and developed primarily to meet the PAF requirement for an affordable, [22] unsanctionable, fourth-generation, lightweight, multi-role combat aircraft as a replacement for its large fleet of Nanchang A-5C bombers, Chengdu F-7P/PG interceptors, and Dassault Mirage III/5 fighters, with a cost of US$500 million, divided equally between Pakistan and China.

Boeing simulations showed that the aircraft was controllable with one engine at idle reverse and the other at full forward thrust in a gear up, flaps 15° configuration. With flaps 25 and gear down, it was not possible to maintain level flight. The go-around would have been successful if the left engine thrust reverser doors had not been deployed.
