The invention discloses a butterfly-shaped aircraft without a middle shaft, which relates to the technical field of aviation aircrafts, and specifically comprises a pair of hollow brushless direct current motors without a middle shaft, which form an aircraft main body and are symmetrically arranged up and down, and paddles arranged on the two hollow brushless direct current motors, and the two hollow brushless direct current motors are symmetrically arranged up and down; the paddles on the upper and lower hollow brushless direct current motors are arranged in opposite directions; when the aircraft flies, paddles on the two hollow brushless direct current motors rotate reversely, the aircraft is controlled to ascend and descend by adjusting the rotating speeds of the two hollow brushless direct current motors, the upper hollow brushless direct current motor and the lower hollow brushless direct current motor rotate in a differential mode to achieve steering when steering is needed, and the rotating speeds of the upper hollow brushless direct current motor and the lower hollow brushless direct current motor are synchronous when steering is not needed. And load balancing. The main power source mechanism adopts a double-power up-and-down symmetrical installation mode, the structure is more compact, the occupied space is smaller, and the stability, the balance and the survivability are better.

    本发明公开了一种无中轴蝶形飞行器,涉及航空飞行器技术领域,具体包括构成飞行器主体的一对上下对称安装的无中轴空心无刷直流电机和设置在两个空心无刷直流电机上的桨叶,上下两个空心无刷直流电机对称放置,且上下两个空心无刷直流电机上的桨叶反向设置;在飞行器飞行时,两个空心无刷直流电机上的桨叶反向旋转,通过调整两个空心无刷直流电机转速控制飞行器上升和降落,需要转向时使上下两个空心无刷直流电机差速旋转实现转向,不需要转向时上下两个空心无刷直流电机转速同步,负载均衡。本发明主动力源机构采用双动力上下对称安装方式,结构更加紧凑,占地空间更小,稳定性、平衡性、抗毁性也更好。
