Cabin Door Adjustment Analysis28Ground Power Unit for Aircraft
1Theoretical Analysis
The aircraft enters pressurization mode as it begins its takeoff roll, and this continues until the cabin pressure returns to the landing field's level after touchdown.
Jinfly Analyzes that during the pressurization process, the pressure difference between the inside and outside of the aircraft generates an outward pressure, which presses the cabin door against the door frame.
Pressure differential fluctuations can cause pressure variations, simulating a non-linear or irregular force applied to the cabin door outwardly. The pressure changes affect the door's mechanism and also influence the cabin door warning system.400HZPower Source Aircraft Power Vehicle
Hatch Mechanism Analysis
The main mechanisms of the door can be divided into the following two types:
1Gripper Mechanism: Handle Cam Disc-Hinge shaft torsion tube rotating mechanism.
2Locking Mechanism: Handle Cam Disc-Up-and-down flipping leaflet motion mechanism.
