A stall that results in the complete disruption of the airflow through the compressor is referred to as a compressor surge. The severity of the phenomenon ranges from a momentary power drop barely registered by the engine instruments to a complete loss of compression in case of a surge, requiring adjustments in the fuel flow to recover normal ...
In most low-speed and low-pressure cases, rotating stall comes prior to compressor surge; [8] [9] however, a general cause-effect relation between rotating stall and compressor surge has not been determined yet. [6] On a constant speed line of a compressor, the mass flow rate decreases as the pressure delivered by the compressor gets higher.
The slightly kinked diagonal line on the main part of the map is known as the surge (or stall) line. Above this line is a region of unstable flow, which is an area best avoided. A compressor surge or compressor stall causes an abrupt reversal of airflow in the compressor. Compressor blades create a pumping action by working as airfoils.
The settlement cost Tecumseh approximately $7 million, according to a report in Crain's Detroit Business. The lawsuit, which was consolidated before U.S. District Judge Sean Cox in 2009, centers on a secret meeting between executives of the companies as well as Panasonic Corp., and an Italy-based components company.
Hydrolock (a shorthand notation for hydrostatic lock or hydraulic lock) is an abnormal condition of any device which is designed to compress a gas by mechanically restraining it caused by a liquid entering the device.

A compressor surge is a disruption of the airflow through a gas turbine jet engine that can be caused by engine deterioration, a crosswind over the engine's inlet, ice accumulation around the engine inlet, ingestion of foreign material, or an internal component failure such as a broken blade. While this situation can be alarming, the engine may ...
The sound produced by compressor surge is called turbo flutter and the repeated, high speed cycling will cause a cyclic torque on the compressor and may lead to increased stresses on the bearings and compressor impeller. [2] A blowoff valve is designed to release pressure in the intake system when the throttle is closed.
