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 modi fi cation details of the cooler is provided to lower the temperature of the cockpit through a large quantity of pneumatic calculation and demontration.Key words : cockpit ; cooling ability ; cooler收稿日期：2010-04-10；修订日期：2011-01-081 座舱高温的原因分析该型飞机座舱冷却装置属于涡轮通风式，每套装置包括一台空气散热器和一台涡轮冷却器。由发动机压缩器引出的高温、高压空气，先经过空气散热器散热，而后在涡轮冷却器里进一步邹 辉 等：高超声速湍流高效模拟算法第31卷 第1期2011年 2月飞 机 设 计AIRCRAFT DESIGN V ol. 31 No. 1Feb 2011
