我要讲的是在航空发动机工厂日常生产中可以看得见和听得到的那种燃烧现象。 在生产中判断一台航空发动机工作的好坏在很大程度上是要依靠在试车时对排气火焰的观察,通过对排气火焰的观察,看看各个缸是否都在进行工作,工作中有无间断现象,各缸排气火焰的颜色怎样,火焰的长短如何以及是否均匀,再听听发动机工作时的声音是否良好,迭样便可以在基本上掌握其燃烧过程是否正常,在航空发动机试车中,除了依靠 What I am talking about is the kind of combustion that is visible and audible in the daily production of an aero-engine plant. To judge whether an aero-engine works well or not in production depends largely on the observation of the exhaust gas flame during the test run. By observing the exhaust gas flame to see if each cylinder is working or not, during work There is no intermittent phenomenon, the color of the cylinder exhaust flame, how the flame length and uniformity, and then listen to the sound of the engine when the work is good, Diego can basically grasp the combustion process is normal, the aeroengine Test, in addition to rely on
