摘　　要：对四轮升压式空气循环制冷系统进行了稳态仿真,并与已有的研究数据进行对比。进一步针对系统主要的扰动源,分析系统的温度扰动特性。仿真结果表明:当引气温度或冲压空气温度发生扰动时,系统温度随之变化,其变化程度与扰动程度相当;而引气压力扰动会造成系统温度大幅度变化,引气压力扰动对四轮升压式空气循环系统制冷能力影响最为剧烈。本文为环控系统的设计和优化提供参考。In this paper,the steady state simulation of four-wheel booster air circulation refrigeration system is carried out,the result of which is compared with the existing research data.Further,the temperature disturbance characteristics of the system is analyzed combined with the main system disturbance source.Simulation results show that when the temperature of the bleed air temperature or ram air disturbance occurs,the system temperature changes,the degree of which agrees with the disturbance degree.However the bleed air pressure disturbance will cause the system temperature to change greatly,that is to say,the bleed air pressure disturbance to the four-wheel booster air circulation refrigeration system influence is most intense.This paper provides reference for the design and optimization of the environmental control in the future.
