Claims

[Scope of utility model registration request]

A gas turbine engine control device that performs closed-loop control to match the rotational speed of a gas generator to a predetermined target rotational speed includes a surge detection means for detecting the occurrence of surging, and a surge detection means for detecting the occurrence of surging based on the output from the surge detection means. a surge determining means for determining the strength of the surging that has occurred; a correcting means for correcting the target rotational speed of the gas generator so as to avoid surging based on a determination output from the surge determining means; 1. A control device for a gas turbine engine, comprising: display means for displaying that the target rotational speed of the gas generator is under correction control.
