Research on fixed attack angle attack angle and height flying of hypersonic aircraft

Abstract

Attack angle is a most important factor that affect the stability of aircraft no matter for supersonic type or hypersonic type aircraft. And height is another factor that will affect the force and moment of the whole dynamic system by change the density of air and finally it will also affect the stability of the whole system. So in this paper a kind of virtual flying with fixed attack angle and height is proposed to testify the rightness of the hypersonic aircraft model and air coefficient. It is a new and meaningful model testifying method for complex flying systems.
