Abstract: Cockpit temperature condition,is one of common and important factors which have influence on pilot's efficiency.A mathematical model of the cockpit temperature control system（CTCS）has been established on the basis of theoretical analysis and experimental data.According to the theory of automatic control the dynamic and static characteristics of CTCS have been calculated and simulated by means of an electronic computer.The effects of each parameter on the dynamic characteristics of CTCS have been studied systematically,and a quite good combination of parameters is provided.Finally,improvement of CTCS has been investigated and the results of calculation and analysis are presented.
