Problems solved by technology

[0002] The solar-powered UAV has the characteristics of large wingspan and great flexibility, which leads to serious deformation of the wing of the UAV during the shutdown, transfer and initial stages of take-off. It is necessary to design an auxiliary support structure on the outer wing; this structure is only used for ground operations and initial take-off. The stage plays a protective role, and it has no effect in other stages (including: after takeoff, air flight and landing); at the same time, it also brings extra weight and aerodynamic resistance to the solar drone, so it is very necessary to design a Detachable auxiliary support for solar drones

Embodiment Construction

[0040] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0041] Aiming at the situation that the auxiliary support structure will bring extra weight and aerodynamic resistance to the solar UAV, the detachable auxiliary support structure of the solar UAV designed in the present invention requires that the detachable auxiliary support can complete the shutdown and sliding of the solar aircraft. While protecting the structure during the initial stage of running and takeoff, it will fall off automatically after takeoff. A detachable auxiliary support structure for a solar unmanned aerial vehicle of the present invention can achieve this purpose, and it can protect the structure during ground operations such as transfer and taxiing according to the requirements of use; At the same time, due to the action of gravity, it will automatically disengage, which can reduce the structural weight and aerodynamic resistance. At the same t...

Abstract

The invention discloses solar unmanned aerial vehicle falling-off type auxiliary supporting structure and method. The structure comprises a light connector, an auxiliary supporting rod, a connecting structure, a wheel fork and an aircraft wheel, wherein the light connector is connected with the unmanned aerial vehicle; the auxiliary supporting rod is connected with the light connector. The upper end of the connecting structure is connected with the auxiliary supporting rod, and the lower end of the connecting structure is connected with the wheel fork. The upper end of the wheel fork is connected with the connecting structure, and the lower end of the wheel fork is connected with the airplane wheel. The structure can play a protection role in ground transfer and take-off stages, and can automatically fall off after take-off, so that the weight is saved, and the resistance is reduced; and meanwhile, the structure has the characteristics of simple form, no need of redundant electric and magnetic control systems, replaceability, convenience in subsequent maintenance and the like.

Description

technical field [0001] The invention relates to the field of solar-powered aircraft landing gear, in particular to an auxiliary supporting structure for a solar-powered aircraft. Background technique [0002] Solar UAVs have the characteristics of large wingspan and great flexibility, which lead to serious deformation of the wings of the UAV during the shutdown, transfer and initial stages of take-off. It is necessary to design auxiliary support structures on the outer wings; this structure is only used for ground operations and initial take-off. The stage plays a protective role, and it has no effect in other stages (including: after takeoff, air flight and landing); at the same time, it also brings extra weight and aerodynamic resistance to the solar drone, so it is very necessary to design a Detachable auxiliary support for solar drones. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the deficiencies of the prior...
