Patent ID: 6895325

Claim:
A turbine engine overspeed control system for a gas turbine electric powerplant, comprising: a compression relief system operational to deprive air from one or more turbines located within said gas turbine engine by rapidly removing air from a combustion section of said turbine engine and directing said air out of said turbine engine through one or more compression relief outlets; an air directing system operational to de-optimize the angle at which air entering an inlet portion of said turbine engine impinges one or more sets of blades of a compressor turbine located therein; one or more sensors for determining an overspeed condition of said turbine engine; and control software in communication with said one or more sensors, said control software sending a signal to said compression relief system and/or said air directing system in response to an overspeed signal from said one or more sensors; wherein upon detection of an overspeed condition, said compression relief system, said air directing system, or the combination thereof, is activated to rapidly slow the rotational speed of said turbine engine.
