Embodiment 1

[0039] Such as figure 1 As shown, a streamlined coaxial multi-rotor UAV that can adapt to harsh environments includes a fuselage module 1, an arm module 2, a landing gear module 3, an upper shell module 4, and a flight control system 5; the arm module 2 is arranged along the circumference of the fuselage module 1. The arm module 2 is used to provide power to drive the fuselage module 1 to hang, fly forward, turn, etc. The flight control system 5 can drive the arm module 2 to generate power.

[0040] Such as figure 2 As shown, the interior of the fuselage module 1 is provided with a control cabin 11, a battery cabin 12, and a load cabin 13; the fuselage module 1 is mainly used to support, fix and load the flight control system 5 and task load of the drone, and bear various The static load and dynamic load transmitted by the parts; the carbon fiber fuselage 14 is made of composite materials through molds, with good molding effect, high finish and light weight. All the electro...

Embodiment 2

[0063] Compared with the traditional six-axis and six-propeller layout, the UAV in the present invention adopts a four-axis and eight-propeller design, which has higher load capacity, wind resistance stability and flight safety.

[0064] The coaxial structure design is adopted, and the pulling force of the arm module 2 is greater under the same volume. In order to facilitate the carrying and transportation of the drone, the arm module 2 adopts a quick-release storage method, in order to meet the heavy-duty mission requirements of the drone platform. The UAV platform needs to provide sufficient power and has high requirements for structural strength, so the carbon fiber integrated molding process is used in the processing process to ensure the structural strength of the carbon fiber arm 24;

[0065] In this embodiment, a simulated coaxial test platform is set up, and two brushless motors 21 are horizontally confronted, the pulling force data under different spacing, different sp...

Abstract

The invention discloses a streamline coaxial multi-rotor unmanned aerial vehicle capable of adapting to severe environments, and the unmanned aerial vehicle comprises a fuselage module, an arm module, an upper shell module, an undercarriage module and a flight control system; a battery cabin, a control cabin and a load cabin are arranged in the fuselage module, and the flight control system is arranged in the control cabin; the flight control system is used for receiving and sending an instruction, and a load device is installed in the load cabin; the aircraft arm module comprises a brushless motor, a propeller, an aircraft arm quick release end and an aircraft arm; the aircraft arm module adopts a coaxial double-propeller structure design; the undercarriage module comprises an undercarriage quick release end, an undercarriage vertical rod and an undercarriage cross rod, and the aircraft body module and the upper shell module are pulled and locked to present an integrated streamline appearance design; the aircraft arm module is detachably connected with the aircraft body module, and the undercarriage module is detachably connected with the aircraft body module, so the unmanned aerial vehicle can be quickly disassembled and assembled. The unmanned aerial vehicle is convenient to disassemble and assemble, can bear resistance in a hostile environment, and is stable in operation.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a streamlined coaxial multi-rotor unmanned aerial vehicle that can adapt to harsh environments. Background technique [0002] Unmanned aircraft, also known as UAV, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on the UAV, but there are equipment such as autopilot and program control device. Compared with manned aircraft, unmanned aerial vehicles have the advantages of small size, low cost, convenient use, low requirements on the combat environment, and strong battlefield survivability, and are favored by armies all over the world. The successful development and application of UAVs on the battlefield has opened a new chapter in non-contact warfare dominated by long-distance attack intelligent weapons and information weapons. [0003] UAVs fly in the air and can perform various combat t...
