载人飞艇雷电防护设计和适航符合性验证

Study of Manned Airship Lightning Protection Design and Airworthiness Compliance Validation

摘要:

载人飞艇被雷电击中时，为了避免雷电流对飞艇产生影响飞行安全的破坏，在载人飞艇设计时就需要考虑构建雷电防护通道，并在研制过程中对设计进行适航符合性验证。基于对载人飞艇雷电防护适航要求的设计和落实过程，研究AS700 载人飞艇的雷电防护设计和适航符合性验证方法。首先根据飞艇的结构和材料构建雷电流通道，然后根据所建立的雷电流通道在飞艇的各种极限飞行姿态下进行雷电接闪仿真分析，确保雷电流通道合理并满足要求，最后梳理、选取关键设备/部件开展雷电适航符合性验证试验。结果表明：AS700 载人飞艇的雷电防护设计符合适航要求，获得了TC 证书。

Abstract:

When a manned airship is struck by lightning, in order to avoid damage to flight safety caused by lightning currents, we need to consider building lightning protection channels in the design of the manned airship and conduct airworthiness compliance verification during the development process. This article studies the lightning protection design and airworthiness compliance verification methods of AS700 manned airships. It simulates the lightning exposure of manned airships in thunderstorm and lightning environments, constructs the lightning current circuit of manned airships, and conducts lightning compliance tests on key components and materials to confirm that the lightning protection design of AS700 manned airships meets airworthiness requirements.
