The invention relates to the technical field of aircrafts, and discloses a ducted fan power low-cost high-speed long-endurance layout aircraft which comprises an aircraft body and wings. A ducted fanis arranged at a position, close to a tail, of the aircraft body, and the ducted fan and the aircraft body are coaxially arranged. The ducted fan and the aircraft body are coaxially arranged, the ducted fan and the aircraft body are integrated into one body, a windward area is reduced, a radius is smaller than that of a propeller, a rotating speed is high, the aircraft is suitable for high-speed flight, and the speed can be remarkably increased compared with that of a piston engine-propeller layout aircraft; high-speed layout that the ducted fan and the piston engine are matched depends on a characteristic of low oil consumption of the piston engine, high-speed flight can be achieved and fuel loading weight of the aircraft is remarkably reduced, the whole aircraft weight is decreased, andcost is reduced; and under the condition of the same fuel weight, the working time is longer than that of jet power, and endurance is improved.

    本发明涉及飞行器技术领域,公开了一种涵道风扇动力低成本高速长航时布局的飞行器,包括机身、机翼,机身靠近尾部的位置设置有涵道风扇,涵道风扇与机身同轴设置。本发明采用涵道风扇与机身同轴设置,涵道风扇与机身融为一体,减小迎风面积,且半径较螺旋桨小,转速高,适用于高速飞行,相较于活塞发动机‑螺旋桨布局飞行器能显著提高速度;涵道风扇与活塞发动机搭配的高速布局,依靠活塞发动机低耗油特点,能达到高速飞行且显著减小飞行器装载燃油的重量,以降低全机重量并降低成本;同等燃油重量情况下较喷气动力工作时间更长,提高航时。
