Research on Simulation Analysis Method of Civil Aircraft Fairing Area

As a typical complex cabin, the aircraft fairing area has a coupling relationship among multiple parameters such as equipment operating state, surface temperature and cabin environment, which makes it difficult to obtain the accurate cabin temperature of aircraft fairing area based on a single simulation method. This paper proposes a one-dimensional and three-dimensional co-simulation analysis method for aircraft fairing area, and verifies the accuracy of simulation analysis method based on fairing area temperature test data of an aircraft. The results show that the average deviation between test temperature and simulated temperature is 5.8 °C, and the calculation accuracy can meet the engineering application. The analysis method has high accuracy and value for engineering application.
