基于目前航空器雷电附着区研究时多采用试验方法,理论划分研究不多。以某类航空器为研究对象,应用“尖端效应”理论,对雷云起电、发展机理、飞行中航空器的带电机理及雷电先导初始附着机制等进行研究,进一步理论划分航空器雷电附着区域。依据GJB3567《军用飞机雷电防护鉴定试验方法》和SAE ARP5416《飞机雷电试验方法》中相关方法,对该航空器的1∶3缩比模型进行雷击附着点试验,并与国内外相关划分结果进行对比,试验结果证明了划分区域的正确性和该雷电附着区划分方法的可行性。该方法一定程度上为包括航空器在内的多种导体的雷电附着区划分研究提供了参考。
Based on the current aircraft lightning attachment area more than the use of experimental methods, theoretical research is not much. With a certain type of aircraft as the research object, this paper studies the electrification of thunderclouds, the mechanism of development, the charging mechanism of aircraft in flight and the initial attachment mechanism of lightning pilot by applying the theory of “tip effect”, and further divides the lightning attachment area of aircraft. According to GJB3567 “Military Aircraft Lightning Protection Identification Test Method” and SAE ARP5416 “Aircraft Thunder Test Method”, the 1: 3 reduction ratio model of the aircraft was subjected to lightning attachment point test, and compared with the relevant domestic and international classification results, The test results prove the correctness of the divided area and the feasibility of the method of dividing the lightning attachment area. This method provides a reference for the research of the lightning attachment area of many kinds of conductors including the aircraft to some extent.
