In this Paper, the mechanic properties and sealing performance of the aircraft fabric rubber seal during flight are studied. First, the mechanic parameters, geometric structure, loading method of different aircraft cabin door fabric rubber seals, and gas conditions are analyzed. Second, the modified gas leakage rate formula of fabric rubber seal within wide ranges of temperature and gas pressure is derived based on the previous gas leakage rate formula of fabric rubber seal and the gas leakage rate experimental results. Then, the gas leakage rate prediction method of multicontact sealing surfaces is established. Finally, the variation law of the aircraft gas leakage rate with the altitude are determined based on the configuration number of the aircraft fuselage doors and the finite element results of the aircraft door seals. The research results will provide reliable scientific guidance for the mechanical performance evaluation and sealing performance prediction of fabric rubber seals.
