A review of aerodynamic layout design methods for high-speed flight aircraft
Whether it is used as weapons or as carriers,the high-speed aircraft has a broad development.Mastering hypersonic technology means occupying the commanding heights of the aerospace field.The design process of high-speed flight vehicle is discussed.The main process included the design of reference shape,shape parameterization,the calculation of aerodynamic characteristic and iterative optimization.The aerodynamic shapes of high-speed flight vehicles and some new aerodynamic shapes are introduced.In terms of parameterization methods,the principles and characteristics of the spline method,linear shape function,CST method and Free-Form Deformation are analyzed.The current methods of obtaining aerodynamic characteristics are introduced.The optimization algorithm in the process of aerodynamic optimization is introduced.At present,high-speed flight vehicles still have the shortcomings of lack of systematic and long iteration period.However,with the continuous development of both computers and theories,the design method of aerodynamic shape for engineering high-speed flight vehicles will be more and more perfect.
