The invention provides a sea-air cross-medium coaxial nested ducted fan aircraft and a working method thereof. The aircraft comprises a fuselage profile, a horizontal empennage, a vertical empennage, an inner and outer coaxial nested ducted fan system and a ducted tilting mechanism. The horizontal tails are symmetrically distributed on the left and right sides of the fuselage tail; the vertical empennage is arranged at the upper end of the tail part of the fuselage; the internal and external coaxial nested ducted fan systems are symmetrically distributed on the two sides of the middle of the fuselage. The duct tilting mechanism is arranged in the aircraft body, can control the tilting angle of the duct, can be matched with a fan rotating speed electric control system to adjust the rotating speed of the two rotors, realizes switching of two medium operation modes, has flight attitudes and working modes of different sea and air task types, and effectively enhances the universality of the aircraft. Therefore, the method can adapt to complex environmental conditions.

    本发明提供了一种海空跨介质共轴嵌套涵道风扇飞行器及其工作方法。飞行器包含机身外形,水平尾翼,垂直尾翼、内外共轴嵌套涵道风扇系统以及涵道倾转机构;水平尾翼对称分布在机身尾部左右两侧;垂直尾翼在机身尾部上端,其对称面与机身对称剖面重合;内外共轴嵌套涵道风扇系统对称分布在机身中部两侧;在机身内部设有涵道倾转机构,能够控制涵道的倾转角度,可以配合风扇转速电控系统调节两种转子的转速,实现两种介质运行模式切换,兼具海空不同任务类型的飞行姿态和工作模式,有效增强了飞行器的通用性,使得其能够适应复杂的环境条件。
