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...
