Lifting-pushing type large-scale solar-powered unmanned aerial vehicle capable of taking off and landing in non-runway field and hovering

Abstract

The invention provides a lifting-pushing type large-scale solar-powered unmanned aerial vehicle capable of taking off and landing in a non-runway field and hovering. The unmanned aerial vehicle has the layout of front-and-back parallel wings in a ladder shape; solar batteries are laid on the whole upper surface of a back wing; an elevon with the overall span is installed on the trailing edge of a front wing, and solar batteries are laid on other areas of the upper surface of the front wing except the elevon; four vertical plates are fixedly arranged on the lower surface of the back wing, and the lower end surfaces of the four vertical plates are fixedly connected with the four end surfaces of the front wing in the span direction by stay bars; a power propulsion system is fixedly installed on the leading edge of the back wing; and two vertical lifting systems are respectively fixed in two spaces formed by the front wing, the back wing and the stay bars. According to the lifting-pushing type large-scale solar-powered unmanned aerial vehicle, the problem of ultra-short distance/vertical takeoff and landing of a large-scale solar-powered airplane is solved by increasing the direct lifting power and reducing the takeoff field length, and additionally, the direct lifting power can be provided in a near space to realize spot hovering to perform a task.

Description

technical field [0001] The invention relates to the technical field of solar unmanned aerial vehicles, in particular to a lift-type large-scale solar unmanned aerial vehicle that can take off and land on a non-runway site and can hover. Background technique [0002] Solar drones rely on the solar energy collected during the day to fly during the day and store part of it for night flights. The layout of solar drones is closely related to the laying of solar cells and energy collection. It needs to lay enough solar cells to meet the needs of aircraft flight. For the requirement of a task load of more than 200 kilograms, in order to meet the laying of photovoltaic cells and high aerodynamic efficiency of the near-space solar aircraft, the wingspan of the aircraft will reach more than 100 meters. [0003] At present, the solar-powered aircraft takes off and lands in the following ways: wheeled taxiing, manpower delivery, vehicle-mounted, etc. In view of the fact that the stand...

AI Technical Summary

Problems solved by technology

In view of the fact that the standard airport runway is only about 70 meters wide, and for large-scale aircraft over 100 meters, it is difficult to take off and land with conventional wheeled taxis, and manpower delivery and vehicle-mounted vehicles are also not competent.

In addition, the current solar-powered UAV uses the thrust method, which cannot achieve fixed-point hovering to perform tasks
