飞机典型外部照明设备定量测试方法研究

Research on aircraft ground test methods for aircraft lighting system

摘要:

飞机外部照明系统是影响飞机安全性的重要系统，飞机照明系统除开展必须的设备鉴定试验外，通常还需开展照明系统机上地面试验，即对照明灯性能进行定量测试。在我国有一些HB 和GJB 文件对照明灯的测试内容做了介绍，但只是对照明灯定量测试提出了详细检测要求，并没有说明检测方法及检测设备选用，依据检测要求无法有效的开展实际测试。本文针对标准文件的检测要求，分析了机上地面试验检测原理，说明选用怎样的检测设备，最终形成了一套完整的针对飞机外部照明系统的机上地面试验实施方法步骤。并以某典型飞机的照明系统机上地面试验为例，详细列举了测试试验判据及其试验数据处理说明。本文可为各种型号的飞机开展照明系统机上地面试验提供指导，为适航取证试验提供参考依据。

Abstract:

The external lighting system of the aircraft is an important system affecting the safety of the aircraft. In addition to carrying out necessary equipment qualification tests, the aircraft system usually also needs to carry out on-board ground tests of the lighting system, which is a quantitative test of the performance of the lighting lamps. In China, there are some HB and GJB documents that introduce the test content of lighting, but only put forward detailed testing requirements for the quantitative test of lighting, and do not explain the testing methods and equipment, and the actual test cannot be effectively carried out according to the testing requirements. In view of the testing requirements of the standard documents, this paper analyses the detection principle of the in-flight ground test, explains what kind of testing equipment is selected, and finally forms a complete set of in-flight ground test implementation methods and steps for the aircraft external lighting system. Taking the on-board ground test of the lighting system of a typical aircraft as an example, the test criteria and test data processing instructions are listed in detail. This paper can provide guidance for various types of aircraft to carry out on-board ground tests of lighting systems, and provide a reference for airworthiness certification tests.
