Description

technical field [0001] The invention belongs to the interdisciplinary field of computational electromagnetic structural strength, and in particular relates to an analysis method for integrated analysis of radome force, heat and electricity. Background technique [0002] With the continuous development of aerospace technology, the performance of various aircraft has made breakthroughs in different fields. The game between major powers is now not just a game between hard power. The strength gap between aircraft is also an important point that cannot be ignored. In the design of the aircraft, the aircraft radome, because it is located at the forefront, undertakes the important task of protecting key electronic systems such as the aircraft radar guidance system. Therefore, the electromagnetic check and strength check of the aircraft radome are very important for the design of the composite material structure and even the design of the entire aircraft. The radome in the aircra...
