Abstract
Systems and methods are provided that use compressed gas from a tank in an aircraft to avoid and/or recover from a compressor surge. Systems and methods are provided that use compressed gas from a tank to startup a gas turbine engine in an aircraft, where the gas turbine engine is configured as a prime power engine for the aircraft.
Claims20
An anti-surge system comprising:
- a tank of compressed gas included in an aircraft;
- a gas turbine engine included in the aircraft;
- and
- a controller configured to cause compressed gas from the tank to be injected into a compressor of the gas turbine engine in response to detection of a compressor surge and/or a potential compressor surge.

A relight system comprising:
- a tank of compressed gas included in an aircraft;
- and
- a gas turbine engine configured as a prime power engine for the aircraft, the gas turbine engine comprising a combustor and a compressor, wherein the combustor and/or the compressor is configured to receive compressed air from the tank during a startup of the gas turbine engine.
A method comprising:
- detecting a compressor surge and/or a potential compressor surge in a gas turbine engine of an aircraft;
- receiving compressed gas from a tank located in the aircraft;
- and
- injecting the compressed gas received from the tank into a compressor of the gas turbine engine in response to detection of the compressor surge and/or the potential compressor surge.
