2007, "Application Guideline for Centrifugal Compressor Surge Control Systems," Gas Machinery Research Council.
Centrifugal compressor surge and its prevention have drawn significant attention in compressor literature and editorial content.
Compressor surge is sometimes viewed as a common occurrence but design of a proper surge control system should be regarded as both a necessary design practice and an effective risk-mitigation measure.
In order to ensure the system is designed properly for its various and often competing requirements, operators will choose to verify component selection, response time and behavior through a dynamic compressor surge model.
The new design is aimed at eliminating compressor surge
at high power take-off, by providing more rigorous tip clearance control, and is based on Pratt & Whitney's 112-inch PW4000 engine design which has proven experience with 3 million hours and 1.
I can guess, though: violent compressor surge
, catastrophic blade failure, severe vibration, primary structure failure, impact into terrain.
is defined and discussed in detail, along with the types of instrumentation (controllers, valves, pressure and temperature transmitters) available, and which of these are most suitable for controlling surge.
can occur when compressors are subjected to rapid transients, such as the one following emergency shutdown (ESD) or power failure.
This safeguard prevents compressor surge
, which could damage the turbocharger.
The new design, aimed at eliminating compressor surge
at high power during take off, will go into production at the beginning of 2003 and will be made available to airlines for incorporation at overhaul beginning in March 2003.

Other applications include compressor surge
control and compressor suction pressure control.
