雷击直接威胁飞行安全,为了进一步确定飞机的雷击特性,依据SAE-ARP5416和国内相关标准的规定,利用基于有限元法的数值仿真技术对飞机雷击附着点和雷击附着区域的划分展开研究。以空客A320飞机为例,按照飞行过程中可能遭受的雷击情况,对其进行了等比例模型下的建模仿真。提出了一种新的飞机雷击附着区域划分的数值仿真方法,研究了数值仿真模型建立的相关问题,并对飞机雷击附着区域中的1A区域进行划分,并将数值仿真结果与SAE-ARP5414A标准结果进行了比较。提出的方法对飞机的防雷设计和相关研究有重要的参考价值。
In order to further determine the lightning strike characteristics of the aircraft, the lightning strike is directly threatened the flight safety. According to the requirements of SAE-ARP5416 and relevant national standards, the numerical simulation technology based on the finite element method is used to study the division of lightning strike attachment points and lightning strike attachment zones. Take Airbus A320 as an example, according to the possible lightning strikes during the flight, it is modeled under an equal-proportion model. A new numerical simulation method for aircraft lightning strike attachment zone division is proposed. The related problems of numerical simulation model establishment are studied, and the 1A zone in the airplane lightning strike attachment area is divided. The numerical simulation results are compared with the SAE-ARP5414A standard results Compared. The proposed method has important reference value for aircraft lightning protection design and related research.
