Viscous interference effect, real gas effect and lean gas effect in high-altitude and high-speed flight have become the major basic scientific problems that determine whether the future spacecraft can achieve safe flight, precise control and guidance. The viscous interference effect, real gas effect and The effect of rarefied gas on the aerodynamic characteristics of high altitude high speed aircraft is reviewed. The development process of aerodynamic layout design optimization is reviewed. The aerodynamic layout design and optimization results of the typical high speed high resistance and drag ratio aircraft are given.
