4. Air Cycle Machine
(Figure 2)
A. The air cycle machine (ACM) houses a turbine, a compressor, and a fan, all mounted on the same
shaft. Air from the secondary heat exchanger is expanded across the turbine to provide the rotational
drive for the entire ACM assembly. The air which passes through the turbine is cooled by the
expansion. The turbine can be bypassed when this cooling is not needed.
B. The compressor boosts the pressure of the air from the primary heat exchanger before it enters the
secondary heat exchanger. A check valve allows the compressor to be bypassed when the turbine is
not active.
C. The fan forces air through the ram air duct when the airplane is on the ground. In flight, ram air
bypasses the fan through a cooling air check valve.
自己慢慢翻译吧,估计你也能看懂 .再给你个ACM更换的章节号,可能不同机型看着不一样,但是最起码不会让你乱找AMM21-51-04
再给你个图片,对了,如果不会可以再找我,但是这个要加分,算是辛苦钱吧.
