A method for attitude control of high-altitude aircraft by using jet flow

Abstract

The invention discloses a method for controlling the attitude of high-altitude aircraft by using jet flow, which relates to the field of high-altitude attitude control of aircraft. The method adopts local encryption in velocity space to simulate the interference effect of jet flow and hypersonic thin incoming flow. The method can The jet amplification factor can be obtained efficiently and accurately, and then the flight attitude of the aircraft can be controlled efficiently and accurately.

Description

technical field

[0001] The invention relates to the field of high-altitude aircraft attitude control, in particular to a method for controlling the attitude of high-altitude aircraft by using jet flow. Background technique

[0002] During the flight of winged aircraft, the attitude control is often realized by the deflection of rudder surfaces such as ailerons, vertical tails, and body flaps. However, under high-altitude conditions, the incoming flow is thin, the dynamic pressure is low, and the control efficiency of the rudder surface is insufficient. Attitude control usually requires the aid of a Jet Reaction Control System (RCS).

[0003] Under vacuum conditions, the jet reaction force / moment can be directly determined from the jet conditions. As the aircraft flies in the atmosphere, there will inevitably be an interference effect between the incoming flow and the jet, which will change the distribution of variables such as pressure and friction on the surface of the ai...
