反推包皮的打开与关闭

1、此课件说明 个人说明全部用绿色字体 英文原文用黑色与红色 黑色中文则在技术论文抽取C涵道的打开与关闭（A321 B-1880）航线工作常涉及一些部件的更换、测试、检查工作需要打开C 涵道包皮来接近内涵区域，而航线工作的时间压力特性则导致飞机刚停稳靠桥，工作者便立即开启风扇包皮和C 涵道反推包皮以达到快速通风散热目的。但此举有可能造成发动机涡轮叶片的损伤因为涡轮机匣的热膨胀冷收缩速率要比叶片的大，因此过早开启反推包皮，外界的机坪冷空气会对涡轮机匣快速冷却收缩，从而造成叶片与机匣内壁刮蹭（图11）。轻则工作者能听到叶片刮蹭的声音，重则叶片损伤（北方基地尤为明显，哈尔滨、沈阳、长春等地都曾发生类似情
