  • 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

  • surge line — The boundary between the gas turbine operating region and the region where the compressor surge is certain …   Aviation dictionary

  • 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

  • surge line — Line on compressor map which represents the minimum stable flow at each pressure ratio, below which the compressor output is unsteady …   Dictionary of automotive terms

  • surge — An unstable condition in which the airflow breaks down over the compressor or turbine because the blades are at very high angles of attack. This condition can occur either because the aircraft is flying at a high angle of attack or very low… …   Aviation dictionary
