Abstract
A UAV preferably has 6 rotors mounted on an H-Frame setup with two parallel longitudinally extending support beams with a cross beam. The rotors are mounted along the longitudinal extending support beams, with one rotor mounted at each end and one motor mounted at the cross beam. Such an arrangement is more efficient than a helicopter of similar disk size and will be more efficient than a traditional hex rotor setup when lifting heavy payloads at a construction site.
Claims15
An unmanned aerial vehicle comprising:
- a frame including a longitudinal beam having a first end, a second end, an upper surface and a lower surface and a first lateral beam connected to the lower surface of the longitudinal beam at the first end, a second lateral beam connected to the lower surface the longitudinal beam at the second end and a third lateral beam connected to the upper surface of the longitudinal beam between the first end and the second end;
- a first propulsion unit mounted to an end of the first lateral beam of the frame and including a first motor configured to operate at a plurality of speeds, a shaft rotated by the motor, a first propeller, mounted above the first lateral beam rotatably coupled to the first motor via the shaft and having a first hub and a first plurality of blades mounted on the hub, the blades having a pitch that is varied by a rack gear;
- a second propulsion unit mounted to an end of the second lateral beam of the frame and including a second motor configured to operate at a plurality of speeds, a second propeller, mounted above the second lateral beam and rotatably coupled to the second motor and having a second hub and a second plurality of blades mounted on the second hub;
- a third propulsion unit mounted to an end of the third lateral beam of the frame and including a third motor configured to operate at a plurality of speeds, a third propeller mounted above the third lateral beam and rotatably coupled to the third motor and having a third hub and a third plurality of blades mounted on the third hub and having blade tips configured and located to create blade tip vortices that act on the first and second plurality of blades.
A first propulsion unit configured to be mounted to an end of a first lateral beam of a frame of an unmanned aerial vehicle, said propulsion unit including a first motor configured to operate at a plurality of speeds, a shaft rotate by the motor, a first propeller, mounted above the first lateral beam rotatably coupled to the first motor via the shaft and having a first hub and a first plurality of blades mounted on the hub, the blades having a pitch that is varied by a rack gear.
