Research on Civil Aircraft Air-conditioning Pack Prognostic Based on Performance Evaluation
Air-conditioning pack of civil aircraft provides air at suitable pressure and temperature for us-ers.It has serval characteristics such as complex operating environment and high failure rate.This article describes a performance evaluation method of air-conditioning pack base on temperature compensation.It is based on the principle of air-conditioning system,airline operation and maintenance experience to a-nalysis parameters of typical operation fault and parameters of air-conditioning pack combined with the extrapolated missing parameters base on the compressor temperature rise characteristic function with the design and test flight data.With this method,the air-conditioning pack can be effectively monitored and early warned so that condition based maintenance can be realized.Practice shows that this method can ef-fectively reduce the fault rate of air-conditioning system and improve the efficiency of aircraft operation.
