Yawing pneumatic control augmentation type lift-body vehicle

The invention discloses a yawing pneumatic control augmentation type lift-body vehicle which comprises a body and a lateral tangent plane, wherein the lateral tangent plane is positioned on two sides in the rear of the body; the lateral tangent plane is a curved surface; as the curved surface is close to the rear of the body, the slope of the curved surface is gradually increased relative to a central axis of the body; the lateral tangent plane is perpendicular to an XOZ plane of the vehicle. An expansion-compression process allowing the rear body to laterally flow is constructed only through the lateral tangent plane based on a pneumatic principle, the yawing stability of the vehicle can be effectively improved, and the problems such as structure, thermal protection and pneumatic elasticity/pneumatic thermoelasticity brought by the process of mounting a heading stability plane are solved.
