Abstract
A control system for a rotor assembly includes a plurality of sensors configured to detect a lead-lag rate of each rotor blade of a plurality of rotor blades rotatable around a shaft and a flight control computer configured to generate lead-lag compensation signals based on the detected lead rate and lag rate of each rotor blade to control each rotor blade.
Claims20
A control system for a rotor assembly comprising:
- a plurality of sensors configured to detect a lead-lag rate of each rotor blade of a plurality of rotor blades rotatable around a shaft;
- and
- a flight control computer configured to generate lead-lag compensation signals based on the detected lead rate and lag rate of each rotor blade to control each rotor blade.
A rotor control assembly, comprising:
- a rotor control computer configured to receive as inputs detected lead-lag rates from sensors located on a plurality of rotor blades rotating around a rotor shaft, to generate a lead-lag compensation signal based on the measured lead-lag rates, and to generate a rotor blade control signal based on the lead-lag compensation signal.
A method of controlling a rotor system, the method comprising:
- detecting a lead-lag rate of each of a plurality of rotor blades;
- generating a lead-lag compensation signal based on the detected lead-lag rate;
- and
- controlling the plurality of rotor blades based on the lead-lag compensation signal.
