  2. Thrust reversal - Wikipedia

    en.wikipedia.org/wiki/Thrust_reversal

    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 ...

  3. Herbst maneuver - Wikipedia

    en.wikipedia.org/wiki/Herbst_maneuver

    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.

  4. Target-type thrust reversal - Wikipedia

    en.wikipedia.org/wiki/Target-type_thrust_reversal

    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]

  5. Rolls-Royce RB529 Contrafan - Wikipedia

    en.wikipedia.org/wiki/Rolls-Royce_RB529_Contrafan

    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.

  6. Powerback - Wikipedia

    en.wikipedia.org/wiki/Powerback

    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 ...

  7. Republic XF-84H Thunderscreech - Wikipedia

    en.wikipedia.org/wiki/Republic_XF-84H_Thunderscreech

    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 ...

  8. Forward-swept wing - Wikipedia

    en.wikipedia.org/wiki/Forward-swept_wing

    Forward-swept wings designs, some whose design had begun during the prewar period, were developed during World War II, independently in Germany, the Soviet Union, Japan, and the United States. An early example to fly, in 1940, was the Soviet Belyayev DB-LK , a twin-boom design with forward-swept outer wing sections and backwards-swept tips.

  9. CAC/PAC JF-17 Thunder - Wikipedia

    en.wikipedia.org/wiki/CAC/PAC_JF-17_Thunder

    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.
