compressor bleed air — Air taken out of the compressor section of a gas turbine engine to prevent compressor stall and operate cabin pressurization and air conditioning systems. Air may also be bled from the compressor for boundary layer control … Aviation dictionary
Bleed air — in gas turbine engines is compressed air taken from within the engine, after the compressor stage(s) and before the fuel is injected in the burners. While in theory bleed air could be drawn in any gas turbine engine, its usage is generally… … Wikipedia
Compressor stall — A compressor stall is a situation of abnormal airflow resulting from a stall of the aerofoils within the compressor of a jet engine. Stall is found in dynamic compressors, particularly axial compressors, as used in jet engines and turbochargers… … Wikipedia
Air cycle machine — An air cycle machine (ACM) is the refrigeration unit of the environmental control system used in pressurized turbine powered aircraft. Normally an aircraft has two to three of these machines arranged in a system called a pack . The cooling… … Wikipedia
Air start system — An air start system is a power source used to provide the initial rotation to start large diesel and gas turbine engines. Compared to a gasoline (petrol) engine, diesel engines have very high compression ratios to provide for reliable and… … Wikipedia

bleed valve — A valve designed to relieve the back pressure in a compressor, which helps to reduce the angle of attack of the rotor blades and prevent compressor stall and compressor surge. A bleed valve permits higher mass airflow through the compressor and… … Aviation dictionary
Axial compressor — Axial compressors are rotating, aerofoil based compressors in which the working fluid principally flows parallel to the axis of rotation. This is in contrast with centrifugal, axi centrifugal and mixed flow compressors where the air may enter… … Wikipedia
Centrifugal compressor — Centrifugal compressors, sometimes termed radial compressors, are a sub class of dynamic axisymmetric work absorbing turbomachinery. Centrifugal impeller with a highly polished surface likely to improve performance … Wikipedia
cross-bleed — i. An air ducting system used in multiengine turbojet aircraft in which compressor bled air from one engine can be directed to the other engine and can be used to operate an air starter. ii. A pneumatic system designed in such a way that it is… … Aviation dictionary
Components of jet engines — Diagram of a typical gas turbine jet engine. Air is compressed by the fan blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which… … Wikipedia
