AI Technical Summary
Existing technologies lack effective methods to verify the unlocking time of the cockpit door depressurization lock under rapid depressurization conditions, resulting in failure to meet airworthiness requirements.
An experimental device was designed, including a vacuum environment simulation component and an experimental environment simulation component. The device simulates a high-altitude environment using a vacuum pump and a vacuum chamber, and measures the unlocking time of the pressure relief plate by combining a displacement sensor and a release trigger switch.
It has achieved accurate verification of the cockpit door depressurization lock unlocking time, meeting airworthiness requirements, and the device has a simple structure, is easy to implement, and has low cost.
