ABSTRACT:
A governor configured to regulate the rotational velocity of one or more rotors of an aircraft by adjusting a collective blade pitch of the one or more rotors. In one embodiment, the governor comprises a control monitor, a maximum pitch module, a rotor module, and a pitch adjustment module. The control monitor is configured to monitor one or more flight control inputs that are controllable by an operator of the aircraft. The maximum pitch module is configured to dynamically determine a maximum collective blade pitch based on the one or more flight control inputs monitored by the control monitor. The rotor module is configured to monitor information related to the rotational velocity of the one or more rotors. The pitch adjustment module is configured to (i) receive information related to the rotational velocity of the one or more rotors from the rotor module and (ii) adjust the collective blade pitch of the one or more rotors to regulate the rotational velocity of the one or more rotors.
