The embodiment of the invention discloses a distributed coaxial duct power system and an aircraft comprising the same. According to one specific embodiment, the system comprises a plurality of ducted wing units distributed in parallel, each ducted wing unit comprises a ducted main body, a first propeller assembly and a second propeller assembly, and the ducted main body is used for containing the first propeller assembly and the second propeller assembly; the first propeller assembly and the second propeller assembly are coaxially arranged, and the second propeller assembly can be folded in the direction away from the first propeller assembly. According to the distributed coaxial duct power system and the aircraft, the ducted wing units are distributed along a thrust line to form wings, and the first propeller assembly and the second propeller assembly are coaxially arranged, so that the area of a propeller disc can be doubled on the premise that the sizes of the first propeller assembly and the second propeller assembly are not increased, and the propeller efficiency can be further improved. In addition, the second propeller assembly is arranged in a foldable mode, air resistance can be reduced, and the cruising efficiency is improved.
本公开的实施例公开了分布式共轴涵道动力系统及包括该动力系统的飞行器。该系统的一具体实施方式包括多个并列分布的涵道机翼单元,其中,涵道机翼单元包括涵道主体、第一螺旋桨组件和第二螺旋桨组件,涵道主体用于容纳第一螺旋桨组件和第二螺旋桨组件;第一螺旋桨组件与第二螺旋桨组件共轴设置,第二螺旋桨组件可朝背离第一螺旋桨组件的方向折叠。该实施方式中多个涵道机翼单元沿推力线分布以形成机翼,又因为第一螺旋桨组件和第二螺旋桨组件共轴设置,可以在不增加第一螺旋桨组件和第二螺旋桨组件尺寸的前提下,使桨盘面积增加一倍,进而可以提高桨效。此外,第二螺旋桨组件可折叠的设置,可以减小空气阻力,提高巡航效率。
