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 inventors (one also as inventor of target-type) states that the design can increase the reverse thrust to 50% of the original thrust. [3] In an earlier development in 1954 called "locks for jet thrust reversers", the design for thrust reversal also contain a flap device to help decelerate and the main purpose of the thrust reverser was to ...
the Reverse thrust device for jet engines. John Vincent Atanasoff (October 4, 1903 – June 15, 1995) was an American physicist and inventor of Bulgarian origin, best known for being credited with inventing the first electronic digital computer. [10]
The wheels are attached to a hydraulic jacking mechanism which can lift the towbar to the correct height to mate to both the airplane and the tug, and once this is accomplished the same mechanism is used in reverse to raise the tow bar wheels from the ground during the pushback process.
Kitchen Rudder. Image from the 1916 U.S. patent. Enhanced design to the Kitchen Rudder. Image from the 1990 U.S. patent. KLM Fokker 70 with reverse thrust applied. The two surfaces behind the engine can be seen in the deployed position, diverting the engine exhaust gases (hence thrust) forward.
The thrust to propel the aircraft forward comes from its propellers or jet engines.Reverse thrust for backing up can be generated by thrust reversers such as on the Boeing C-17 Globemaster III, or reversible pitch propellers such as on the Lockheed C-130 Hercules, a rare procedure known as powerback.
A multi-axis thrust vectoring engine nozzle in motion. Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.
Stephenson valve gear is a convenient arrangement for any engine that needs to reverse and was widely applied to railway locomotives, traction engines, steam car engines and to stationary engines that needed to reverse, such as rolling-mill engines. It was used on the overwhelming majority of marine engines.
