摘　　要：某型飞机夏季飞行座舱温度高的问题由来已久,在外界环境温度为30℃时,座舱温度高达40℃以上,对飞行人员的身心健康产生了不同程度的影响。通过本文分析得出结论:该型飞机座舱高温问题,主要是由于现有制冷设备的设计制冷能力受到某些环境因素的制约而没能完全发挥作用造成的。通过计算提出了从机外引入冲压空气,降低空气散热器冷边系统的空气温度,以改善机务舱与外界热交换条件的方法来解决该型飞机夏季飞行座舱高温的问题。Being of long standing,the high temperature trouble of the cockpit has always been the serious fault in summer flight for a certain model of the aircrafts.When the aircrafts fly in summer,the ambient temperature of 30℃ and the cockpit temperature above 40℃ will have a great influence on the health of the flight personal.Analyzing the trouble,we obtain the following conclusion：First the trouble is not because the cooling ability of the cooler can not satisfy the requirement,but because the cooling ability of the existing cooler is confined by some enviromental factors so that it can not function fully;then an idea to modify the cold paramenters of the cooler is put forward;finally the specific modification details of the cooler is provided to lower the temperature of the cockpit through a large quantity of pneumatic calculation and demontration.
