The invention belongs to the technical field of propellers, and discloses a double-engine aircraft propeller automatic feathering control device which comprises a second engine automatic feathering electromagnetic valve and a first engine automatic feathering electromagnetic valve, and the second engine automatic feathering electromagnetic valve and the first engine automatic feathering electromagnetic valve are connected through a circuit. When one of the second engine automatic feathering electromagnetic valve and the first engine automatic feathering electromagnetic valve works, the other one is in a disconnected state. By means of the design, the automatic feathering system of the double-engine aircraft can only execute automatic feathering of one propeller at the same time, and the flight safety of the aircraft is improved; compared with an original design system, only line change is involved, no additional device is added, and it is guaranteed that the cost of the aircraft is controllable.

    本发明属于螺旋桨技术领域,公开了一种双发飞机螺旋桨自动顺桨控制装置,包括2号发动机自动顺桨电磁活门和1号发动机自动顺桨电磁活门,采用电路将2号发动机自动顺桨电磁活门和1号发动机自动顺桨电磁活门连接起来,使得2号发动机自动顺桨电磁活门和1号发动机自动顺桨电磁活门中的一方工作时,另一方处于断开状态。本发明的设计使得双发飞机的自动顺桨系统同时只能执行一个螺旋桨的自动顺桨,提高飞机飞行的安全性;本发明相对于原来的设计系统,仅涉及线路的更改,没有增加额外的器件,保证了飞机的成本可控。
