Classification: CPC B | IPC B

Claim 12:
13. A vehicle comprising:
a gas turbine engine;
a propeller operatively coupled with the gas turbine engine;
an electric propeller governor having a motor and a flyweight governor spring mechanically coupled with the motor;
a control system, comprising:
a sensor;
a controller communicatively coupled with the sensor, the controller configured to:
receive, from the sensor, data indicative of a propeller speed of the propeller;
receive a commanded power level;
energize the motor of the electric propeller governor to provide a first preload on the flyweight governor spring as a result of receiving a commanded power level:
determine whether the propeller speed exceeds a propeller speed threshold, the propeller speed threshold being different than a propeller speed set point; and
as a result of the propeller speed exceeding a propeller speed threshold, cause adjustment of the propeller speed set point from a first set point to a second set point to change the propeller speed of the propeller;
wherein in causing adjustment of the propeller speed set point to change the propeller speed of the propeller based on whether the propeller speed exceeds the propeller speed threshold, the controller is configured to energize the motor of the electric propeller governor to change a preload on the flyweight governor spring from the first preload to a second preload, wherein the second preload corresponds to the second set point, and wherein the second set point corresponds to the commanded power level.
