Method and arrangement for gas turbine engine surge control
The invention relates to a surge control method for a gas turbine engine (10). The method includes providing a gas turbine engine (10) having a compressor (20), a combustor (30), downstream of the compressor (20), with a hot gas path, a turbine (40) downstream of the combustor (30), with a hot gas p...

| description | The invention relates to a surge control method for a gas turbine engine (10). The method includes providing a gas turbine engine (10) having a compressor (20), a combustor (30), downstream of the compressor (20), with a hot gas path, a turbine (40) downstream of the combustor (30), with a hot gas path. The method further includes monitoring the gas turbine engine (10) for a potential surge condition, controlling a blow-off flow from the compressor (20), based on the monitoring for the control purpose of avoiding the surge condition, and directing the blow-off flow to at least one of the hot gas paths so as to bypass at least a portion of the combustor (30). |
