Difficulties in aerodynamic design problems of the winged hypersonic reentry vehicle

The winged hypersonic reentry vehicle has been a hot research topic in recent years and aerodynamic design is the key of aircraft design. In this paper the development, advantages and the overall mission profile of the winged hypersonic reentry vehicles are introducted for understanding the difficulties more clearly. Detailed introduction of the difficulties problems are conducted from five aspects in the aerodynamic design of the aircraft, including multi-constraint complex plane symmetry aerodynamic configuration design, effects of the real gas on aerodynamic characteristics, difference conversion method between flight and ground, reaction control system (RCS) jet interference effects on aerodynamic characteristics and the uncertainties of aerodynamic data. Moreover this paper also expounds the significance of these difficulties problems on the overall design and gives the preliminary solution, which could provide some references for the winged hypersonic reentry vehicles on the aerodynamic design.
