• compressor stall-margin curve — An operating curve of a gas turbine engine, which shows the relationship between the compression ratio of the engine and the mass airflow that must be maintained throughout the engine. If either of these factors goes out of limits, a compressor… …   Aviation dictionary

• compressor blade — A rotating aerofoil on the disc of a compressor in a gas turbine engine. A compressor blade adds energy to the air by increasing its pressure and density as it moves through the engine. Compressor blades are made of special steel, alloys, or… …   Aviation dictionary

• engine sections — The main components of any engine. In the case of a gas turbine engine, these are the fan (if it is fan engine), compressor, combustion, and turbine sections. In the case of reciprocating engines, the four sections are the nose, power, super… …   Aviation dictionary

• Engine cooling — is cooling an engine, typically using either air or liquid.OverviewHeat engines generate mechanical power by extracting energy from heat flows, much as a water wheel extracts mechanical power from a flow of mass falling through a distance.… …   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

• 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

• 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

• Engine Alliance GP7000 — The Engine Alliance GP7000 (known as the GP7200 for a brief time period) is a new turbofan jet engine that will incorporate advanced technologies of proven wide body products, originally from the world s No.1 and No.3 aero engine manufacturers,… …   Wikipedia

• engine station designation — All gas turbine engines, except those with bypass ducts, are given station designations from 0 to 9, with the station 0 denoting the area ahead of the inlet where the airflow is undisturbed and the number 9 denoting the exhaust flow conditions of …   Aviation dictionary
