Abstract

The invention belongs to the technical field of airplane hydraulic system hatch door control, and relates to a multi-angle control technology for a hatch door in an airplane hydraulic system. The characteristic that when the hatch door is on different open positions, the operating stroke of an actuator cylinder piston rod is different is fully utilized, the actuator cylinder of the airplane hatch door is specially designed, the multi-angle control demand of the hatch door is satisfied, and the operation is simple.

Description

technical field [0001] The invention belongs to the technical field of aircraft hydraulic system cabin door control, and relates to an aircraft multi-angle control cabin door. Background technique [0002] The door control system belongs to the hydraulic system in the aircraft mechanical system, which uses hydraulic oil to drive the actuator to perform actions, and uses the hydraulic reversing valve to complete the opening and closing of the door. At present, the door control technology at home and abroad is relatively simple, and the door can only be opened and closed on the ground. If it needs to be opened to a certain angle in the air, it is necessary to separately design a set of complex air rod mechanism, which makes the structure complicated. Contents of the invention [0003] The technical problem solved by the invention is to provide a cabin door with simple structure and multi-angle control. [0004] The technical solution of the present invention is: the cabin ...
