有翼高超声速再入飞行器是近年来的研究热点，气动设计是飞行器设计的关键。为更清楚地认识有翼高超声速再入飞行器气动设计的难点问题，对有翼高超声速再入飞行器的发展、优势及总体任务剖面进行了介绍，从五个方面详细介绍了该类飞行器气动设计的难点问题，包括多约束复杂面对称气动布局设计、高温真实气体效应对气动特性影响、天地差异与天地换算方法、RCS喷流干扰对气动特性的影响、气动数据不确定度等技术研究，简要阐明了这些难点问题对总体设计的重要性及初步的解决思路，为有翼高超声速再入飞行器气动设计可提供一些参考。
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.
