Rudder type thrust vector control engine

Abstract

The invention relates to a rudder type thrust vector control engine. According to the rudder type thrust vector control engine, horizontal rudders and vertical rudders which are processed with high-technical-index heat-resistant materials are additionally arranged at a tail jet nozzle of a jet engine, the angles of the rudder surfaces of the horizontal rudders and the vertical rudders are adjusted, and therefore the effect of changing the thrust direction of the engine can be achieved, and multivariate vector thrust of the engine can be achieved. The invention further provides a technical scheme that the horizontal rudders or the vertical rudders are designed to be composed of two parts which are mutually symmetric, can rotate towards the two sides of the tail jet nozzle respectively when not in use and rotate out from the center area of airflow of the tail jet nozzle so as to reduce the ablation time of the rudders under the high-temperature airflow and a technical scheme that the horizontal rudders or the vertical rudders are designed on the inner side of the tail jet nozzle so that the horizontal rudders or the vertical rudders are completely wrapped by tail jet pipes and shielded in the tail jet nozzle, and therefore the stealth performance of a fighter plane adopting a stealth design can be improved. The rudder type thrust vector control engine has the remarkable characteristics of being simple in structure and low in technical difficulty.

Description

technical field [0001] The invention relates to a rudder-type vector engine, which realizes the attitude control of the aircraft by adding a rudder to the tail nozzle of the jet engine, and has the effect of changing the direction of thrust similar to that of the vector engine, belonging to an aero-engine technology field. Background technique [0002] The attitude control of existing jet aircraft mainly finishes by horizontal empennage, vertical empennage, canard or directly by wing. The latest vector engine can adjust the thrust direction by changing the direction of the jet engine’s tail nozzle, and realize the attitude control of the aircraft. However, this technology is difficult to realize. At present, only the United States and Russia have carried out practical applications. Our country is still in research. The U.S. solution is to use a rectangular nozzle with two pairs of deflection plates, up and down, and left and right respectively, which can be deflected in th...

Problems solved by technology

The American solution is to use a rectangular nozzle, with two pairs of deflectors up and down and left and right respectively, which can be deflected in the up and down, left and right directions respectively to change the direction of the jet. Although the structure is simple, it cannot be turned 360 degrees. It belongs to the binary thrust vector engine; Russia's solution is to spherically hinge the tail nozzle and the engine to achieve 360-degree steering of the tail nozzle. Although the structure is complex, it can provide thrust in all directions and is a multi-element thrust vectoring engine.
