As a kind of morphing aircraft, hypersonic variable-sweep aircraft can actively change the sweep angle and surface area of the wing during the flight. The aircraft can obtain the best aerodynamic shape to adapt to different flight missions and flight environments. According to the shape characteristics of variable-sweep aircraft, the mathematical model of variable-sweep aircraft in space flight is established firstly. The analysis model needed for the control system design is obtained by appropriate simplification. Then, based on the aerodynamic data, the aerodynamic parameters under different sweep angles are calculated. And the aerodynamic characteristics and lift-drag ratio characteristics are analyzed. Finally, the general law of the rise of attack angle and sweep angle of glide flight with optimal aerodynamic characteristics is proposed. It provides a valuable reference for the control method of variable-sweep wing aircraft.
