The Force State Analysis of the Service Door on an Airliner
Abstract:
The crew emergency evacuation security system is a life-saving device, the ultimate function of which is to save the life of the aircraft crew in a new regional airliner at high altitude. The system is used to push the service door with translational motion for a suitable distance. Before the system was started, the force state of the service door was got with the fluid mechanics knowledge. When the system was started, after a period of pressure relief time, the aircraft cabin pressure was calculated with the Bernoulli's Equation. The movement trajectory and the force state of the service door were obtained by the computational fluid dynamics theory and numerical simulation method. All of the above work must lay a theoretical foundation for the development of the crew emergency evacuation security system, and ensure the flight safety.
