The invention provides a coaxial line split type contra-rotating double-propeller electric ducted propeller, a ducted propeller engine is fully electrically driven, the design of the ducted cover reduces the noise generated by the propeller engine during normal operation, and the design of the contra-rotating double propellers solves the problem of reaction torque of a single-stage propeller; and the adverse effect of a propeller slip flow field on aerodynamic force of wings and empennages of the aircraft is weakened. Different from a traditional coaxial double-propeller propeller, the designed ducted propeller engine adopts a coaxial line split type design, so that the additional load of a traditional gear transmission group on the engine is reduced, the energy loss during gear meshing is reduced, and the mechanical efficiency of the propeller is improved. The dual-motor dual-control independent circuit increases the safety redundancy of the engine and enhances the flight safety of the aircraft. And meanwhile, the propulsion power of the ducted propeller engine can be reasonably adjusted according to autonomous control under different flight working conditions, and the application requirement for longer endurance time of the aircraft can be met.

    本发明提供了一种共轴线分体式对转双桨电动涵道螺旋桨,该涵道螺旋桨发动机为全电驱动,涵道罩的设计降低了螺旋桨发动机在正常运转时所产生的噪音大小,对转双桨的设计解决了单级螺旋桨的反扭矩问题,并减弱了螺旋桨滑流流场对于飞行器机翼及尾翼气动力的不利影响。不同于传统共轴双桨螺旋桨,所设计涵道螺旋桨发动机采用共轴线分体式设计降低了传统齿轮传动组对发动机的额外载荷,减少齿轮啮合时的能量损耗,提高了螺旋桨的机械效率。双电机双控独立电路增加了发动机的安全冗余度,增强飞行器飞行的安全性。同时,针对不同飞行工况下的自主控制能够合理调节涵道螺旋桨发动机的推进功率,有助于满足飞行器更长续航时间的应用需求。
