Fixed leading edge is an important part of aircraft wing, and its design should consider the influence of temperature. The temperature of the fixed leading edge compartment is affected by the high temperature and high pressure gas inside the bleed air duct and the ambient temperature outside the skin. The temperature, pressure and velocity of the gas inside and outside the compartment are quite different, so it is difficult to converge by computational fluid dynamics (CFD) analysis directly. In this study, the method of combining Simulink with CFD is proposed to solve the temperature of fixed leading edge compartment in a certain civil aircraft. The calculation method is easy to converge, and the obtained temperature can be directly used in the design of fixed leading edge structures to ensure aircraft safety.
