The invention discloses a water-air amphibious aircraft, and belongs to the technical field of cross-medium aircrafts, the water-air amphibious aircraft comprises a fuselage, coaxial double rotors are embedded in the fuselage, morphing wings are symmetrically arranged on two sides of the fuselage, the morphing wings comprise a front wing and a rear wing, one end of the front wing is slidably connected to the fuselage, and the other end of the front wing is hinged to one end of the rear wing; the other ends of the rear wings are connected to the fuselage in a sliding mode, revolute ailerons are arranged on the rear wings, and the tail of the fuselage is provided with an empennage with a rudder and a power propelling device for providing advancing power. Multi-attitude control and multimode medium transition can be realized through unfolding and folding of the morphing wings and mutual coupling of the revolute ailerons, the rudders and the coaxial double rotors, so that the water-air amphibious aircraft has the common advantages of a fixed-wing aircraft and a rotor aircraft, the problem that the fixed-wing aircraft has great impact force when entering and exiting water is solved, and the service life of the water-air amphibious aircraft is prolonged. And meanwhile, the problems that a rotor aircraft is difficult to control and poor in stability during medium transition are solved.

    本发明公开了一种水空两栖飞行器,属于跨介质飞行器技术领域,包括机身,机身上嵌装有共轴双旋翼,机身两侧对称设有变体机翼,变体机翼包括前机翼和后机翼,前机翼的一端滑动连接在机身上,前机翼的另一端与后机翼的一端铰接,后机翼的另一端滑动连接在机身上,后机翼上设有转动副翼,机身的机尾设有自带方向舵的尾翼和提供前进动力的动力推进装置。通过变体机翼展收、转动副翼、方向舵以及共轴双旋翼相互耦合,可实现多姿态控制和多方式介质过渡,使得本水空两栖飞行器具有固定翼飞行器和旋翼飞行器共同的优点,解决了固定翼飞行器入水出水时存在很大的冲击力问题,同时解决了旋翼飞行器存在的操纵难、介质过渡时稳定性差的问题。
