Problems solved by technology

[0003] However, directly adding fixed wings to the main body of the aircraft will not only significantly increase the overall size of the aircraft, but also significantly increase the overall weight of the main body of the aircraft, resulting in the problem that the load factor of the aircraft is relatively small.

Embodiment Construction

[0023] One of the cores of the present invention is to provide an elevator landing gear for an unmanned aerial vehicle, so as to effectively improve the cruise economy of the aerial vehicle without significantly increasing the size and weight of the aerial vehicle.

[0024] Another core of the present invention is to provide an unmanned aerial vehicle using the above-mentioned lifting and landing gear.

[0025] The elevating and landing gear of an unmanned aerial vehicle disclosed in the embodiment of the present invention includes a wing plate 3 and a landing gear foot 22. The landing gear foot 22 is used to contact the ground and stably support the aircraft. One end of the wing plate 3 and the landing gear The legs 22 are connected, and the other end is used to connect with the aircraft body 1. The landing gear has a raised state and a landing state. When the landing gear is in the raised state, the UAV is in normal flight. When the landing gear is in the landing state, no one Th...

Abstract

The invention discloses an unmanned aerial vehicle and a lifting undercarriage thereof. The lifting undercarriage comprises a wing plate (3) and undercarriage supporting legs (22) used for making contact with the ground, one end of the wing plate (3) is connected with the undercarriage supporting legs (22), the other end of the wing plate (3) is used for being connected with an aircraft body (1),and when the lifting undercarriage rises, the wing plate (3) serves as a fixed wing and is used for improving the lifting force of the aircraft. According to the unmanned aerial vehicle undercarriage,the cruise economy of an aerial vehicle can be improved; and meanwhile, the whole unmanned aerial vehicle is compact in structure, and the weight is kept at a low level.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle and an unmanned aerial vehicle's lifting landing gear. Background technique [0002] The lift and drag characteristics of the fixed wing are currently the most efficient among unmanned aerial vehicles. The lift generated by the wing surface in the best cruise state can reach several or even dozens of times the drag. The typical lift-drag ratio of a small fixed-wing aircraft can reach 7-20; Therefore, for current multi-rotor or other VTOL (vertical take-off and landing) unmanned aerial vehicles, one of the most effective means to improve cruise economy is to add fixed wings. [0003] However, directly adding fixed wings to the aircraft body will not only significantly increase the overall size of the aircraft, but also significantly increase the overall weight of the aircraft body, leading to the problem of a smaller load factor of the aircraft...
