Abstract

Abstract:

Study on changing laws of local temperature environment of ground parking aircraft is a key work to compile local environment spectra and to solve the temperature drift problem of sensors. Therefore, the local temperature monitoring of ground parking aircraft is carried out and the changing laws of different bays are studied. Using the fuzzy clustering method, the bays of an airplane are divided into three groups according to the differences of local temperature. The effect laws of environmental temperature upon local temperature have been studied, and a local temperature model of aircraft is established using structural coefficient and sunlight coefficient as key coefficients, and the temperature of thermometer shelter as argument. Furthermore, ranges of key coefficients in the temperature model of three bay groups have been obtained through statistic method. The results show that bays of one sealing state can have large differences in temperature, and the factors which significantly affect bays' temperature are sunlight, rainfall, bays location and bays' structural form. A comparison of the monitored temperature and the predicted temperature using temperature model shows good agreement and proves that the temperature model possesses good accuracy.

Key words: aircraft structure, temperature environment, local environment, temperature drift, temperature model
