Vertical take-off and landing model aircraft unmanned aerial vehicle

Abstract

The invention provides a vertical take-off and landing model aircraft unmanned aerial vehicle. The vertical take-off and landing model aircraft unmanned aerial vehicle is provided with a rotatable screw propeller, an undercarriage and a solar charging system, overcomes the defects of the conventional model aircraft unmanned aerial vehicle, can vertically take off and land in situ, reduces the requirements on the airfield, can quickly fly at the speed of a flying wing type unmanned aerial vehicle and can also suspend like a helicopter; the undercarriage can protect the body during landing to prevent collision with the ground, and the solar charging system can prolong the duration of flight. In addition, the body is a light wood thin plate framework; a body shell is formed by additionally coating epoxy resin on carbon fiber cloth and is then assembled with the framework; the structure has the beneficial effects that the overall weight of the unmanned aerial vehicle model is reduced, meanwhile the body strength is improved, the decoration to the outer surface is facilitated and a more attractive appearance is achieved.

Description

technical field [0001] The invention relates to a model airplane unmanned aerial vehicle technology, in particular to a model airplane drone which utilizes a rotatable propeller to take off, land and fly vertically. Background technique [0002] In 1914, the two generals of the United Kingdom, Carder and Pichel, proposed to develop a small aircraft that does not need to be piloted. In the past few years, drone technology has developed rapidly. [0003] Model airplanes refer to model airplanes that can fly in the air, and are generally used in fields such as aviation knowledge popularization, theoretical research, model testing, military tools, and photography assistance. At present, the common model aircraft drones include model aircraft helicopters and model aircraft flying wings. Due to the large difference in the structure and layout of the two, they have different characteristics. Model airplane helicopters only have one propeller installed at the top, which mainly r...

AI Technical Summary

Problems solved by technology

Model airplane helicopters only have one propeller installed at the top, which mainly relies on the rotation of the propeller to generate lift and forward thrust. Therefore, the propeller is usually large in size, relatively complex in structure, and provides limited power, so it can only fly at low speeds. In addition, a single propeller is wind-resistant Poor ability, unstable flight, easy to lose balance and cause damage or crash

Model airplane flying wings, also known as full-wing aircraft, adopt a layout method different from conventional aerodynamic layouts. There is no tail, and the main parts of the fuselage are all hidden in the wings. Simply put, it is only the layout of the wings of the aircraft. See There are only wings, no fuselage and landing gear, etc. The fuselage and wings are integrated, so it looks flat from the outside. The advantage of this aerodynamic layout is that it only needs to provide forward thrust during flight. Relying on its own structural characteristics to generate upward lift, the disadvantage is that high-speed flight is required to generate sufficient lift, and the requirements for the site are also high. Since there is no landing gear, the fuselage will wear a lot during take-off and landing, and the collision can easily damage the propeller and control. system

[0004] In addition, most of the existing model airplanes are powered by lithium batteries. Due to the limitation of battery capacity, the flight time and flight distance are limited. charging model airplane
