Wave rider and deformation aerodynamic configuration design method

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
