Electric unmanned aerial vehicle

Abstract

The invention discloses an electric unmanned aerial vehicle. The electric unmanned aerial vehicle comprises a fuselage, two undercarriages and eight motors supported by eight cantilevers connected tothe fuselage, a longitudinal load channel is formed below the fuselage, and the two sides of the longitudinal load channel are symmetrically provided with a first group of four cantilevers and a second group of four cantilevers correspondingly; a first included angle alpha formed between every two adjacent cantilevers of the first group of four cantilevers is same; a second included angle beta formed between every two adjacent cantilevers of the second group of four cantilevers is same; a third included angle theta and a fourth included angle epsilon are correspondingly formed between two adjacent cantilevers between the first group of four cantilevers and the second group of four cantilevers; wherein, alpha is equal to beta, theta is equal to epsilon, and the theta is greater than or equal to 1. 5 times of alpha and less than or equal to 2. 5 times of alpha. According to the electric unmanned aerial vehicle, the longitudinal load channel is formed below the fuselage without shield, loads such as a photoelectric pod propeller and a weapon launcher can be conveniently arranged, the situation that use and operational effectiveness are affected due to interference of the loads and cantilevers as well as a propeller during observation and weapon launching is avoided, and the application range of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-rotor electric unmanned aerial vehicle, in particular to an electric unmanned aerial vehicle with eight rotors. Background technique [0002] With the development of digital navigation and control technology, the UAV field has led a new wave of technology development and is considered to be the commanding height of next-generation technology development. The development of UAV technology in China is particularly eye-catching. With the development of the global general aviation industry, the development of various rotorcraft is also increasing day by day, especially the rotor electric unmanned aircraft, which are widely used in agricultural plant protection, forest fire monitoring, aerial photography, land survey, post-disaster loss assessment tasks. However, the existing rotor UAVs generally have low load levels and unreasonable structural layouts, makin...
