摘要： Unique systems and methods are disclosed to detect and remediate an overspeed condition of a gas turbine engine. Such techniques include sensing rotational speed of a rotating member of a gas turbine engine and providing a first speed threshold that varies with rotational acceleration of this member over a predefined range. An overspeed condition of the gas turbine engine is detected if the rotational speed exceeds this first speed threshold and a second speed threshold. This second speed threshold is greater than or equal to the first speed threshold when the overspeed condition is detected. In response to the overspeed detection, a fuel valve may be actuated to adjust fuel flow to the engine. In one embodiment, an analog circuit compares the first and second speed thresholds to the rotational speed and controls current flow through an actuator for an overspeed fuel valve associated with the engine.
