Research on temperature field distribution calculation of pylon spar on the fire

Abstract According to the advisory notice requirements, engine mounting sections with materials other than steel and Inconel 718 should be verified that they meet the sufficient safety margin under the fire state. In this paper, the influence of the conditions in the fire zone on the structure of the middle area of the pylon front spar is specified, and the fire scene is selected as the most likely position to destroy the integrity of the force transmission path of the structure. By simulating the boundary conditions in the fire zone, the temperature distribution of the middle area of the pylon front spar is obtained.
