The invention relates to the technical field of airplanes, and particularly discloses a short-distance take-off and landing airplane. The airplane comprises a fuselage, two main wings and two empennages. The two main wings and the two empennages are rotatably connected with the fuselage, a first rotation driving system is arranged between the two main wings and the fuselage, and a second rotation driving system is arranged between the empennages and the fuselage; and engines are arranged on the lower surfaces of the main wings and the empennages, and telescopic propellers are connected to output shafts of the engines of the main wings. According to the short-distance take-off and landing airplane disclosed by the invention, the angles between the wings and the airplane body can be changed according to different flight states of the airplane through the self-locking hydraulic motors, and the acceleration and take-off and landing processes can be realized by combining the rotation angles of the wings and only through a set of power system devices on the whole wings; and the power system of the whole airplane occupies a small space of the airplane, and the problems that an existing short-distance take-off and landing airplane is large in weight, poor in flexibility, small in oil carrying amount, small in combat radius and the like are effectively solved.
本发明涉及飞机技术领域,具体公开了一种短距起降飞机;包括机体、两个主翼和两个尾翼,两个主翼和两个尾翼与机体之间转动连接,两个主翼与机体之间设置有第一旋转驱动系统,尾翼与机体之间设置有第二旋转驱动系统;主翼和尾翼的下表面均设置有均设置有发动机,主翼发动机的输出轴上均连接有伸缩式螺旋桨;本发明公开的短距起降飞机通过自锁液压马达能够根据飞机的不同飞行状态来改变机翼与机体之间的角度,结合机翼的旋转角度和仅通过整机翼上的一套动力系统装置即可实现加速和起降的过程,使得整个飞机的动力系统占用飞机的空间小,有效解决了现有短距起降飞机体重大,灵活性不好,载油少,作战半径小等问题。
