Abstract
A control apparatus for a gas turbine engine comprises an accelerating condition detecting mechanism and an operating speed control mechanism. The accelerating condition detecting mechanism detects the degree of acceleration in the engine. The operating speed control mechanism controls, depending upon the degree of the acceleration, the speed for opening variable nozzles installed in the inlet portion of a power turbine of the engine, and/or variable inlet guide vanes installed in the inlet portion of a compressor of the engine.
Claims9
An apparatus for controlling a gas turbine engine of the type including a power turbine, a rotatable compressor, and variable nozzle means, disposed in an inlet portion of said power turbine and movable between at least an opened and a closed position, for controlling the flow rate of a gas into said turbine, said apparatus comprising:
- means for detecting the actual rotation speed of the compressor;
- interactive means for producing a desired compressor rotation speed value in response to user manipulation;
- means for detecting atmospheric temperature;
- means for correcting said desired compressor rotation speed value in response to said detected atmospheric temperature;
- means for calculating the difference between said corrected desired compressor rotation speed value and said detected actual rotation speed;
- and
- position changing means for changing the position of said variable nozzle means at a rate responsive to said calculated difference.
