The invention discloses a three-channel internal and external flow integrated full waverider aerodynamic design method, and relates to near space hypersonic aircraft integrated design. Comprising three three-dimensional internal contraction air inlet channels arranged in parallel in the spanwise direction and an internal/external flow integrated pneumatic transition design. The three three-dimensional internal contraction air inlet channels all adopt a three-dimensional internal contraction basic flow field to carry out streamline tracking design, and the basic flow field of the three-dimensional internal contraction air inlet channel of the internal waverider and an external flow field of the waverider precursor are subjected to coupling design, so that pneumatic transition between the three-dimensional internal contraction air inlet channel of the internal waverider and the waverider precursor of the external waverider is achieved. According to the three-channel internal and external flow integrated full-waverider configuration generated by the design method, the whole lower surface of the three-channel internal and external flow integrated full-waverider configuration completely sits on three-dimensional external compression shock waves, and the good full-waverider characteristic is achieved; the three three-dimensional internal contraction shock waves are all sealed, and full-flow capture of the three three-dimensional internal contraction air inlet channels is achieved. According to the design method, a new thought is introduced for the integrated design of the aircraft waverider forebody and the three-dimensional inward turning air inlet channel.

    一种三通道的内外流一体化全乘波气动设计方法,涉及临近空间高超音速飞行器一体化设计。包括沿展向并联布置的三个三维内收缩进气道以及内/外流一体化气动过渡设计。三个三维内收缩进气道均采用三维内收缩基本流场进行流线追踪设计,将内乘波的三维内收缩进气道的基本流场与乘波前体的外流流场进行耦合设计,使得内乘波的三维内收缩进气道与外乘波的乘波前体实现气动过渡。该设计方法生成的三通道内外流一体化全乘波构型,其整个下表面完全“乘坐”在三维外压缩激波上,具有良好的全乘波特性;三个三维内收缩激波均封口,实现三个三维内收缩进气道的全流量捕获。该设计方法为飞行器乘波前体与三维内转进气道的一体化设计引入新思路。
