轻型运动飞机驾驶舱告警系统适航性技术研究

近年来,轻型运动类飞机(LSA)研制取得突破进展。依据美国材料与试验协会(ASTM标准)开展此类飞机机组告警系统的研究,确保LSA类飞机在不安全的工作状况下,机组能够获取警告信息且能采取适当的纠正操作。本文基于适航条款要求以及相关机型设计经验,总结分析了轻型运动类飞机机组告警系统设计理念及定义方法,对告警方式的分类给出了具体阐述,并结合某型试验样机给出了具体的应用实例,为LSA类轻小型飞机机组告警的适航性技术发展提供了一定的参考。

In recent years, breakthroughs have been made in the development of light sport airplane （LSA）.According to the American Society of Materials and Testing （ASTM standard） to carry out this type of aircraft crew alarm system research,and make sure that the aircraft crew warning system can indicate to the crew the unsafe working conditions of the system, then the crew can take appropriate corrective action after obtaining the warning information .This paper is based on airworthiness terms and related model design experience.And it has Summarized and analyzed the design concept and definition method of the crew alarm system.A detailed description of the classification of the crew alarms has also been given. Finally, Combined with a prototype, a specific application example is given to provide a certain reference for the development of airworthiness technology for light sport airplane crews.
