Abstract

An aerial vehicle connected to or integrated with a work device, including a power source to generate power, a rotor to generate lift used for flight by rotating a propeller, and a power transmission to transmit driving power to the work device.

Claims (17)

1 . An aerial vehicle connected to or integrated with a ground work device performing ground work, the aerial vehicle comprising:

an airframe;

an engine to generate power;

a generator to generate electric power by using the power generated by the engine;

a rotor to generate lift used for flight by rotating a propeller, the rotor comprising a main rotor driven by the power generated by the engine and a sub rotor driven by power generated by the generator or stored in a battery;

a power transmission to transmit the power from the engine to the ground work device;

a wheel; and

support members having a predetermined elasticity and supporting the wheel on the airframe; wherein

the ground work device is attached to the airframe and operated by the power from the engine transmitted by the power transmission;

the ground work device is a tillage device; and

the wheel contacts the ground when the tillage device performs work on the ground to support the airframe on the ground and assist the tillage device in working on the ground in a stable condition.

2 . The aerial vehicle according to claim 1 , wherein the power transmission is configured to transmit rotational power of the propeller as the driving power.

3 . The aerial vehicle according to claim 1 , wherein the ground work device is connected to the airframe of the aerial vehicle as a separate entity and is operated by the driving power transmitted from the power transmission.

4 . The aerial vehicle according to claim 3 , wherein the ground work device is detachable from the aerial vehicle.

5 . The aerial vehicle according to claim 1 , further comprising:

a work controller configured or programmed to adjust the lift generated by the rotor to control at least one of ground work altitude of the ground work device and a depth of the ground work performed by the ground work device on a ground.

6 . The aerial vehicle according to claim 5 , wherein the work controller is configured or programmed to change a direction of the lift generated by the rotor to press the ground work device against the ground.
