The invention discloses a waverider and deformation aerodynamic configuration design method, which realizes wide-range waverider through a variable sweepback airfoil, and adopts different sweepback angles under different Mach numbers to achieve an optimal waverider state under each Mach number. The deformation strategy of the waverider aircraft along the flight profile is as follows: according to the characteristic that the shock wave angle becomes smaller along with the increase of the Mach number, the airfoil is in an original sweepback angle state under the designed Mach number; under the state that the Mach number is higher than the designed Mach number, the airfoil is gradually retracted inwards along with the increase of the Mach number, and the sweepback is increased; and under the state that the Mach number is lower than the designed Mach number, the airfoil gradually expands outwards along with the reduction of the Mach number, and the sweepback becomes smaller. The problem of single-point waverider of a traditional waverider is solved through a waverider and deformation aerodynamic configuration design method, the lift-drag ratio performance of the waverider aircraft under the wide-area condition is improved, and the voyage of the whole flight profile is improved.

    本发明公开一种乘波加变形气动外形设计方法,通过变后掠翼面实现宽域乘波,在不同的马赫数下采用不同的后掠角达到各马赫数下最佳乘波状态。乘波体飞行器沿飞行剖面的变形策略为:根据激波角随马赫数增大而变小的特性,在设计马赫数下,翼面处于原始后掠角状态;在高于设计马赫数的状态下,随着马赫数增大,翼面逐渐向内收起,后掠角增大;在低于设计马赫数的状态下,随着马赫数降低,翼面逐渐向外展开,后掠角变小。通过乘波+变形气动外形设计方法解决了传统乘波体单点乘波的问题,提升了乘波飞行器在宽域条件下的升阻比性能,提升全飞行剖面的航程。
