中文摘要:如何在民用飞机遇险迫降或失事后尽快定位搜救,提高机上遇险人员的生存率,是当前民用飞机设计过程中必须考虑的问题。作为民用飞机应急搜救系统,固定式应急定位发射系统(ELT)可以在飞机遇险时通过自动和人工方式触发,在固定的频率上发射搜救信号,以便搜救组织对遇险人员进行救援。首先提出了固定式ELT系统的设计方案及功能,分析了系统部件的构成,进而提出了固定式ELT系统的性能要求,最后重点阐述了固定式ELT系统的机上设计要求和功能验证过程。
英文摘要:The location and search-and-rescue after aviation accident is closely related to the survival of the people on the aircraft and it should be considered in the development of the civil aircraft design. As the search-and-rescue equipment on the civil aircraft, the fixed emergency locator transmitter (ELT) can be triggered by the auto and manual ways when the aircraft has an accident, and then the ELT can transmit the search-and-rescue signals on the fixed frequencies. Thus the search-and-rescue is organized. Firstly, a design project of the fixed ELT is proposed, including the system function definition and system equipment analyzing. Then the system performance requirements of the fixed ELT are proposed. Finally, the system design requirements and system function validation process are expatiated.
