Research on calculation method of aircraft skin temperature based on parameter sensitivity analysis

Abstract

From the perspective of heat transfer, according to factors that affect skin temperature of civil aircraft, combined with the sensitivity analysis method, this paper proposes a method for calculating the skin temperature of an aircraft without inputting the wind speed outside aircraft. The accuracy of this method is verified by the recovery temperature method, and the wind speed outside aircraft is expanded to explain the applicable scope of this method. The results show that when the wind speed outside aircraft is less than 110 m/s, the maximum deviation between the calculated results of this method and the recovery temperature method is 1.9%, and the calculated results are credible. The method is particularly suitable for ground stop and climb condition that the wind speed outside aircraft is less than 110 m/s and difficult to obtain.
