Abstract
Systems and methods directed to a rotor blade assembly for an unmanned aerial vehicle (UAV) are provided. A system may include a rotor blade assembly including an axle assembly, a first rotor arm supporting a first rotor blade and coupled to rotate about the axle assembly, a second rotor arm supporting a second rotor blade and coupled to rotate about the axle assembly, and a torsion spring coupled to the first rotor arm and the second rotor arm, such that a rotation of one of the first rotor arm or the second rotor arm about the axle assembly applies a spring force to the other of the first rotor arm or the second rotor arm. Additional systems and related methods are also provided.
Claims20
A system comprising:
- a rotor blade assembly comprising:
- an axle assembly,
- a first rotor arm supporting a first rotor blade and coupled to rotate about the axle assembly,
- a second rotor arm supporting a second rotor blade and coupled to rotate about the axle assembly, and
- a torsion spring coupled to the first rotor arm and the second rotor arm, such that a rotation of one of the first rotor arm or the second rotor arm about the axle assembly applies a spring force to the other of the first rotor arm or the second rotor arm.
A method comprising:
- coupling a first rotor arm to rotate about an axle assembly, the first rotor arm supporting a first rotor blade;
- coupling a second rotor arm to rotate about the axle assembly, the second rotor arm supporting a second rotor blade;
- and
- coupling a torsion spring to the first rotor arm and the second rotor arm, such that a rotation of one of the first rotor arm or the second rotor arm about the axle assembly applies a spring force to the other of the first rotor arm or the second rotor arm.
A method comprising:
- rotating one of a first rotor arm or a second rotor arm of a rotor blade assembly about an axle assembly, wherein both the first rotor arm and the second rotor arm are coupled to rotate about the axle assembly;
- and
- applying, by at least one torsion spring coupled to the first rotor arm and the second rotor arm, a spring force to the other of the first rotor arm or the second rotor arm in response to the rotating.
