Novel tailstock type axisymmetric multi-propeller vertical take-off and landing unmanned aerial vehicle

Abstract

The invention discloses a novel tailstock type axisymmetric multi-propeller vertical take-off and landing unmanned aerial vehicle. According to the scheme, the novel tailstock type axisymmetric multi-propeller vertical take-off and landing unmanned aerial vehicle comprises an unmanned aerial vehicle body assembly, a head cover assembly, a tail cover assembly, power propeller assemblies and a symmetric wing assembly. The novel tailstock type axisymmetric multi-propeller vertical take-off and landing unmanned aerial vehicle is characterized in that four wings are symmetrically arranged relativeto an unmanned aerial vehicle body in a crossed shape; the power propeller assemblies are correspondingly contained on the four wings; landing gears with shock absorbing devices are used at the lowerparts of the wings; in addition, the head cover assembly and the tail cover assembly are positioned at the two ends of the unmanned aerial vehicle body to reduce the air resistance in the cruise levelflight process. According to the novel tailstock type axisymmetric multi-propeller vertical take-off and landing unmanned aerial vehicle, through differential control of thrust forces of the four propellers in the vertical taking-off and landing or hovering stage, the attitude stabilization of the unmanned aerial vehicle is guaranteed; maneuvering actions, such as rolling and yawing, of the unmanned aerial vehicle are controlled by using trailing edge flaps and ailerons during horizontal flight; and the novel tailstock type axisymmetric multi-propeller vertical take-off and landing unmanned aerial vehicle is especially suitable for being applied to the fields such as carrier-based unmanned aerial vehicles and power line inspection or places with higher requirements on maneuverability, higher speeds and higher safeties.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a tail seat type vertical take-off and landing unmanned aerial vehicle. Background technique [0002] At present, domestic mainstream UAVs include two categories, one is a rotorcraft that directly provides lift through propellers, and the other is a fixed-wing aircraft that relies on wings to generate lift. These two types of UAVs have their own advantages and disadvantages. The biggest advantage of the rotorcraft is that it can realize vertical take-off and landing, hovering in the air, etc., and its disadvantages are low cruising speed, low energy efficiency, and short cruising time; Man-machines have the advantages of fast speed, long cruising time, and high energy efficiency, but they cannot achieve vertical take-off and landing and rely on a certain distance of the flight path, so they cannot hover; therefore, in recent years, some scholars have compared the high flight ef...

Problems solved by technology

[0004] The present invention aims to solve the defects that the existing vertical take-off and landing UAVs have relatively large aerodynamic resistance, low cruising speed, maneuverability and safety that cannot meet the needs of special occasions when the structural layout is in horizontal flight. A reconnaissance aircraft needs a UAV with high safety, strong maneuverability, high cruising speed and vertical take-off and landing
