Embodiment Construction

[0027] This embodiment is a fixed-wing rotor hybrid UAV,

[0028] refer to Figure 1 to Figure 5 , the fixed-wing rotor hybrid UAV in this embodiment integrates the structures of the existing fixed-wing UAV and the four-rotor UAV, and combines the wings of the fixed-wing UAV with the rotor arm of the four-rotor UAV Organically combined to reduce its structural weight.

[0029] In this embodiment, the first rotor assembly 1 and the third rotor assembly 6 are respectively connected to the first rotor arm 15 through the motor base 21; the second rotor assembly 4 and the fourth rotor assembly 9 are respectively connected to the second The rotor arm 16 is attached. The four-rotor layout is H layout, so that the UAV of this embodiment has a larger wing area, thereby obtaining greater lift. And the four-rotor layout reduces the requirements and restrictions on the site when the fixed-wing UAV takes off and lands, and realizes the vertical take-off and landing of the UAV and the hi...

Abstract

The invention discloses a fixed wing and rotor ring hybrid unmanned aerial vehicle. Integration design is performed on the structures of a fixed wing unmanned aerial vehicle and a rotor ring unmannedaerial vehicle, the characteristics that the rotor wing unmanned aerial vehicle can land vertically and is not limited by taking-off and landing site are combined with the characteristics that the fixed wing unmanned aerial vehicle is high in flying speed, long in voyage, heavy in carrying capacity and high in efficiency; the fixed wing and rotor wing hybrid unmanned aerial vehicle better conformsto the characteristics of aerodynamics by tilting the overall vehicle body, so as to realize rapid flying. When the fixed wing and rotor ring hybrid unmanned aerial vehicle flies rapidly, the vehiclebody tiles forwards, so that the fixed wing is horizontal, and the rotor wing rotates; at the moment, four rotor wings supply lifting power for the unmanned aerial vehicle, and meanwhile, forward flying power is provided, and the posture of the unmanned aerial vehicle is controlled by regulating differential speed between motors; fixed wings of the fixed wing and rotor ring hybrid unmanned aerialvehicle simultaneously supply partial lifting powder, and the combination of the fixed wings and the rotor wings enables the unmanned aerial vehicle to both save energy and increase the flying speedin flying, so as to greatly reduce the express transportation cost and time.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a fixed-wing rotor hybrid unmanned aerial vehicle. Background technique [0002] With the continuous strengthening of the national economy and the gradual maturity and development of e-commerce platforms, the business volume of the express delivery industry has increased rapidly. Although the express delivery industry is in a good development trend, it is also facing many challenges and difficulties, such as logistics warehouse explosion and express delivery delays. UAVs have the characteristics of low manufacturing cost, strong mobility, and low requirements on the task environment. UAVs can be used to solve the express delivery problem in the express delivery industry. At present, express delivery drones have become a development trend. Fixed-wing express delivery drones are not suitable for express terminal delivery due to their high requirements for take-off...
