Air cycle machine: History & Measurement

An air cycle machine (ACM) is the refrigeration unit of the environmental control system (ECS) used in pressurized gas-turbine–powered aircraft. Normally an aircraft has two or three of these ACM. Each ACM and various associated components and pipework are often referred as an air conditioning pack. The air cycle cooling process uses air instead of a…
