Abstract: The winged hypersonic reentry vehicle is a hot research topic in recent years. Aerodynamic design is the key of aircraft design. The development,advantages and the overall mission profile of the winged hypersonic reentry vehicle are introducted for understanding the difficulties more clearly. Detail introduction of the difficult prolbems were conducted form five aspects in the aerodynamic design of the aircraft, including multi complex constraints plane symmetry aerodynamic configuration design, effects of the real gas on aerodynamic characteristics, difference conversion method between flight and ground, RCS jet interference effects on aerodynamic characteristics and the uncertainties of aeroydnamic data. This paper expounds the significance of these difficult problems on the overall design and gives the preliminary solution, this can provide some reference to the winged hypersonic reentry vehicles on the aerodynamic design.

Key words: winged teentry, hepersonic, aerodynamic design, real gas effect, RCS jet interference, difference conversion method between flight and ground, uncertainties of aeroydnamic data
