Abstract
A rotor assembly includes a rotor mast, motor, and a rotor hub. The rotor mast may connect to the motor and to the rotor hub. The rotor mast may be rotatable about a first axis. A plurality of blades may be connected to the rotor hub. The rotor hub may include a shaft that may connect the blades. A swashplate may connect to the rotor mast and to the shaft. A single linkage may extend from a first end to a second end, the first end may be coupled to the shaft and the second end may be coupled to the swashplate. The single linkage may be configured to transfer motion of the swashplate to rotate the shaft about the second axis and thereby rotate the blades about the second axis simultaneously.
Claims20
A rotor assembly comprising:
- a rotor mast connected to a motor and to a rotor hub, the rotor mast being rotatable about a first axis;
- a plurality of blades connected to the rotor hub;
- the rotor hub including a shaft connecting the blades, the shaft being rotatable about a second axis;
- a swashplate connected to the rotor mast and to the shaft;
- and
- a single linkage extending from a first end to a second end, the first end being coupled to the shaft, the second end being coupled to the swashplate, the single linkage configured to transfer motion of the swashplate to rotation of the shaft about the second axis and thereby rotate the blades about the second axis simultaneously.
A rotor assembly comprising:
- a rotor mast connecting a motor to a rotor hub, the rotor mast being rotatable about a first axis that extends through the rotor mast;
- at least two blades connected to the rotor hub;
- a shaft connecting the at least two blades, the shaft being rotatable about a second axis;
- a control rod;
- a swashplate connected to the shaft by the control rod;
- and
- a pitch link connected to the shaft at a center of the shaft as measured along the second axis, the pitch link being configured to rotate the shaft around the second axis and thereby change an angle of attack of the at least two blades simultaneously.
A vehicle comprising:
- a first rotor assembly comprising:
- a first set of at least two blades;
- a first shaft connected to the first set of at least two blades, the first shaft being rotatable about a first axis;
- and
- a first pitch link connected to the first shaft at a center of the first shaft as measured along the first axis and configured to rotate the first shaft along the first axis and thereby change an angle of attack of the first set of at least two blades;
- and
- a second rotor assembly comprising:
- a second set of at least two blades;
- a second shaft connected to the second set of at least two blades, the
- second shaft being rotatable about a second axis;
- and
- a second pitch link connected to the second shaft at a center of the second shaft as measured along the second axis and configured to rotate the second shaft along the second axis and thereby change an angle of attack of the second set of at least two blades.
