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 its components are often referred as an air conditioning pack.
The primary component for the functioning of the cold air unit (CAU) is the Air Cycle Machine (ACM) cooling device. Some aircraft, including early Boeing 707 aircraft, used vapor-compression refrigeration like that used in home air conditioners. An ACM uses no Freon: the air itself is the refrigerant. The ACM is preferred over vapor cycle ...

A foil bearing, also known as a foil-air bearing, is a type of air bearing. A shaft is supported by a compliant, spring-loaded foil journal lining. Once the shaft is spinning fast enough, the working fluid (usually air) pushes the foil away from the shaft so that no contact occurs. The shaft and foil are separated by the air's high pressure ...
Chip Detectors consist of small plugs which can be installed in an engine oil filter, oil sump or aircraft drivetrain gear boxes. Over a period of time, engine wear and tear causes small metal chips to break loose from engine parts and circulate in the engine oil. The detector houses magnets incorporated into an electric circuit.
Fluid statics – or hydrostatics, is the branch of fluid mechanics that studies the condition of the equilibrium of a floating body and submerged body "fluids at hydrostatic equilibrium [78] and the pressure in a fluid, or exerted by a fluid, on an immersed body".
Oil pumps and magnetos are driven by the camshaft drives as well as the Heywood air starter and tachometer. The two-piece crankshaft, with counter-weights, is carefully forged from heat-treated chrome-vanadium alloy steel and drilled for lightness and lubricating oil flow.
