Research on constant attack angle flying of hypersonic aircraft

A kind of imaginary virtual flying with numerical simulation is used to testify the rightness of hypersonic aircraft with air dynamic coefficients. Since the attack angle is the most important factor that affect the stability of the hypersonic or supersonic aircraft, so a kind of virtual flying with constant attack angle is proposed to do the open loop numerical simulation to check the air coefficients of system model. This kind of testing method is very useful for situations that the rightness of the aircraft system model is not guaranteed, especially for complex flying systems. So this new testing method is very meaningful and useful for hypersonic engineering.
