Unmanned aerial vehicle

Abstract

The invention discloses an unmanned aerial vehicle. The unmanned aerial vehicle is characterized in that the vehicle comprises trailing edge tilting wing type fixed wings with a low aspect ratio, one elevating rudder or two lifting ailerons located near the inner sides of the trailing edges of the wings, one or more vertical stabilizers which are located on the symmetrical planes of the vehicle and extend to the upper side and the lower side of the wings, one or more rudders additionally arranged on the rear sides of the vertical stabilizers, a pair of coaxial counter propellers located on the symmetrical planes of the vehicle and the upstream positions of the wings and driven by motors, a receiver and a battery, wherein the middle point of a wing root section chord is located at the upstream position of or aligned with the middle point of a wingtip section chord. The unmanned aerial vehicle can execute high-skill complex tasks which cannot be executed by various traditional fixed wing or rotor wing vehicles; the vehicle can vertically take off and land, fly horizontally in a fixed wing posture and be converted into a rotor wing posture anytime to collect images and videos, and the unmanned aerial vehicle is small, flexible and stable, and is better in maximum speed, cruising ability and energy-saving effect than a rotor wing type vehicle with the equal size and weight.

Description

technical field [0001] The invention relates to the fields of unmanned aerial vehicles and radio / remotely controlled aircraft. Background technique [0002] UAVs have many private and commercial applications as aerial sensor platforms (ie, video acquisition), delivery systems, environmental sensing, and communication relays. They can also be used for various defense related purposes such as ISR (Intelligence Surveillance Reconnaissance), as weapons platforms, and as electronic warfare platforms. They can be classified by size as micro, small, tactical (medium), or strategic (large), and based on their method of aerodynamic lift generation can be further classified as: fixed wing, rotary wing, hybrid wing, or flapping wing. According to the report of the U.S.-China Economic Security and Review Commission, the existing Chinese UAVs lack micro, small, hybrid capabilities, and flapping wings. Types such as: search and rescue, border security, law enforcement and environmental ...
