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 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
Stall speed — Auftriebsbeiwert in Abhängigkeit vom Anstellwinkel Als Strömungsabriss (englisch: stall) bezeichnet man in der Aerodynamik die Ablösung der Luftströmung von der Oberfläche eines angeströmten Gegenstandes. In der Praxis sind darunter Tragflächen,… … Deutsch Wikipedia
Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… … Wikipedia
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
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
stall margin — As it pertains to gas turbine engines, it is the parameter that is the difference between the operating RPM and the RPM at which the compressor blades will stall at any altitude and for transient slam acceleration … Aviation dictionary
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
variable-angle stator vanes — Compressor stator vanes whose angle can be varied. The angle is controlled by the fuel control unit. Varying the stator vane angle ensures that the air directed to the first stage of the compressor meets the compressor at an optimum angle and… … Aviation dictionary
