| Abstract: | Variable configuration aircraft can adapt to different mission requirements and flight environments by changing their own configuration to have good aerodynamic characteristics under different flight conditions. In order to solve the problems of increasing the mass and structural complexity of an aircraft caused in the traditional variable configuration mode, this paper designs a variable configuration aircraft with “throwable wings”. Its conventional configuration can achieve high subsonic cruise, and become a missile to achieve a supersonic speed after throwing off the wings for military purposes such as terminal penetration and strikes. Numerical calculations are carried out under different flight conditions for the two states before and after the configuration, and the aerodynamic performance of the aircraft is preliminarily evaluated. Then, the whole process of the aircraft from throwing off the wings to accelerating is simulated through flight simulation. The research results show that this kind of aircraft can adapt to different flight environments through configuration changes, which provides a reference for the configuration design of high speed variable configuration aircraft. |
