1Compressor 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… …
2Compressor 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… …
3Axial 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… …
4single-spool compressor — A single compressor rotor design of the axial flow type. A single spool compressor will have a single turbine wheel …
5twin-spool compressor — A compressor that has two independently operating low and high pressure compressors driven, respectively, by low and high pressure turbines. Twin spool compressor …
6low-pressure compressor — The front section of a dual spool compressor, also called an N1 compressor or a low speed compressor. It is driven by the last stage of a turbine. The high pressure compressor is called an N2 compressor …
7high-pressure compressor — The second stage compressor in a dual spool gas turbine engine. It is called an N2 compressor. A high pressure compressor is the only one rotated by the starting system of an aircraft …
8dual-spool gas turbine engine — An axial flow turbine engine with two independent axial flow compressors, each driven by its own stage(s) of turbines. The high pressure, or N2 , compressor is speed governed by the fuel control system. The speed of the low pressure compressor,… …
9multispool engine — An arrangement in which there is more than one compressor spool that requires a separate turbine for each spool. In most cases, it is a twin spool engine with a low pressure compressor or a high pressure compressor with corresponding low and high …
10General Electric F404 — The General Electric F404, F412, and RM12 are a family of afterburning turbofan engines in the 10,500 19,000 lbf (85 kN) class (static thrust). The series are produced by GE Aviation. Partners include Volvo Aero, which builds the RM12 variant.… …
