Simulation Analysis on Pressure Load Calculation for Civil Aircraft Antenna Assembly
摘要
Abstract
The structural safety of civil aviation antenna components is one of the important factors to ensure flight safety.In order to investigate the influence of internal and external pressure difference load on the structural safety of civil aircraft antenna components during flight,and to evaluate the rationality of the size design of pressure relief holes for antenna components,This paper adopts the Computational Fluid Dynamics(CFD)method to simulate the load distribution of internal and external pressure difference and the process of ballast change of a typical aircraft antenna component under normal flight and airtight failure conditions.The calculation results show that under normal flight conditions,the differential pressure load of the antenna component is small and relatively uniform,and the internal pressure of the antenna component will decrease with the decrease of atmospheric pressure,and is slightly less than the atmospheric pressure.Under the condition of airtight failure,the pressure differential load in a specific area of the antenna assembly will increase significantly,and the internal pressure of the antenna assembly will rise rapidly when the airtight failure occurs until it reaches a stable value.The research in this paper provides some reference and input for the design of antenna components.关键词
