• compressor efficiency — One of the measures of aerodynamic efficiency. It is measured by the ability of a compressor to compress the air to the maximum pressure ratio with a minimum increase in air temperature. The compression ratio is a measure of compressor efficiency …   Aviation dictionary

• Compressor map — Each compressor (or fan) in a gas turbine engine has an operating map. Complete maps are either based on compressor rig test results or are predicted by a special computer program. Alternatively the map of a similar compressor can be suitably… …   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

• efficiency — [1] The accomplishment of something with the least amount of effort, energy, or fuel. [2] Output of a device, system, or activity, divided by the input necessary to create the output. In a compressor the efficiency would be the work output, as… …   Dictionary of automotive terms

• Scroll compressor — A scroll compressor (also called spiral compressor , scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. It is used in air conditioning equipment, as an automobile supercharger (where it is known as a scroll type… …   Wikipedia

• Centrifugal compressor — Centrifugal compressors, sometimes termed radial compressors, are a sub class of dynamic axisymmetric work absorbing turbomachinery.[1] Centrifugal impeller with a highly polished surface likely to improve performance …   Wikipedia

• 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

• Digital scroll compressor technology — improves the performance of a scroll compressor. Inside a scroll compressor, there are 2 components called scroll sets. The 2 scrolls mesh against each other in the compressor. There are several pockets that are formed when the scrolls mesh with… …   Wikipedia

• Gas compressor — A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are… …   Wikipedia

• Engine efficiency — of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines (1) Internal combustion (gasoline, diesel and gas… …   Wikipedia

• axial-flow compressor — A compressor used in gas turbine engines in which the flow of air is maintained parallel to the compressor shaft. An axial flow compressor is made up of several stages of alternate rotors and stators. The number of stages of compression… …   Aviation dictionary
