Abstract
According to one embodiment, a method for determining a position of a rotor blade includes receiving a plurality of measurements from a plurality of magneto-resistive sensors and determining a position of the at least one magnet based on the received plurality of measurements. In this example, one of the plurality of magneto-resistive sensors and the at least one magnet moves with a rotor blade.
Claims20
A rotorcraft, comprising:
- a body;
- a power train coupled to the body and comprising a power source and a drive shaft coupled to the power source;
- a hub coupled to the drive shaft;
- a rotor blade;
- a grip coupling the rotor blade to the hub;
- and
- a position determination system disposed between the blade and the body, the position determination system comprising:
- at least one magnet;
- and
- a plurality of magneto-resistive sensors proximate to the at least one magnet;
- wherein the at least one magnet is movable relative to the plurality of magneto-resistive sensors as a function of movement of the grip relative to the hub.
