Abstract
Embodiments are directed to obtaining data from at least one sensor, processing, by a processor, the data to determine an independent rotor phase lag for each of a plurality of axes associated with a rotorcraft, and issuing, by the processor, at least one command to provide for on-axis moments in accordance with the independent rotor phase lag for each of the axes.
Claims20
A method of adjusting phasing of a rotor comprising:
- obtaining data from at least one sensor;
- processing, by a processor, the data to determine an independent rotor phase lag for each of a plurality of axes associated with the rotor of a rotorcraft, wherein the data is mapped to commands via a table;
- issuing, by the processor, at least one command to one or more actuators to provide for on-axis moments in accordance with the independent rotor phase lag for each of the axes;
- and
- adjusting phasing of the rotor separately for each of the plurality of axes via operation of the one or more actuators.
2 more elements
An apparatus comprising:
- at least one processor;
- and
- a memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to:
- obtain data from a plurality of sensors;
- process the data to determine an independent rotor phase lag for each of a plurality of axes associated with a rotor of a rotorcraft;
- and
- issue commands to one or more actuators to provide for on-axis moments in accordance with the independent rotor phase lag for each of the axes such that a phase of the rotor is adjusted separately for each of the plurality of axes via the one or more actuators.
4 more elements
A rotorcraft comprising:
- at least one rotor comprising a plurality of blades;
- a plurality of sensors associated with the at least one rotor;
- and
- a control system configured to:
- obtain data from the sensors;
- process the data to determine an independent rotor phase lag for each of a plurality of axes associated with the at least one rotor of the rotorcraft;
- and
- issue commands to one or more actuators to provide for on-axis moments in accordance with the independent rotor phase lag for each of the axes such that a phase of the at least one rotor is adjusted separately for each of the plurality of axes via the one or more actuators.
