摘要:

针对近年来频发的飞机座舱环控系统飞行事故/事件,对国内外发生的飞机座舱环境相关的飞行事故/事件进行了分析。分析表明,压力控制子系统中压力控制器部件失效是造成座舱压力异常事故/事件最重要的原因。基于Simulink 和AEMSim建立了环控系统数学模型,并对一起典型压力异常事故进行仿真复现,对事故中关键部件、关键参数及其风险进行评估,为事故深入调查及预防提供了指导意义,也为环控系统的设计和维修提供了依据。

Abstract:

Based on the aircraft cabin environment related accidents in and abroad in recent years, the flight accidents/incidents data of ECS are analyzed. The result shows that most of the environmental control system accidents/incidents are due to failure or fault of controller component of pressure control subsystem. Subsequently,the ECS system is modeled based on Simulink and AEMSim. A typical accident of ECS in aircraft is implemented in such accident simulation model. The key components and parameters as well as the risk assessment are also researched. This work will increase the efficiency of accident investigation relating to cabin environment. The simulation model can also support the design and maintenance of environment control system.

Key words: aircraft cabin, accident analysis, ECS, pressure regulating, accident simulation
