Abstract

The invention relates to a ducted coaxial twin-screw unmanned aerial vehicle, comprising a power system, a bevel gear transmission system, a control plane regulating system and a rack, wherein the power system comprises three transmission shafts, a motor and a core frame; the bevel gear transmission system comprises upper and lower internal bevel gear disks, a plane pushing bearing, a blade mounting clip, blades and an internal duct; and the control plane regulating system comprises a control plane mounting clip, a bearing, a control plane retaining clip, a steering engine draw rod retaining clip, a steering engine draw rod, a servo steering engine and a steering engine arm. The ducted coaxial twin-screw unmanned aerial vehicle disclosed by the invention has the following beneficial effects that: 1, through the ducted mode, the efficiency of the blades is greatly improved; 2, through the bevel gear transmission system, the effective efficiency of the motor is maximally exerted; 3, through the coaxial twin-screw mode, lifting power can be supplied more efficiently; and 4, through controlling the aircraft attitude in multiple control planes, the unmanned aerial vehicle is more stable.

Description

technical field [0001] The invention relates to a ducted coaxial double-blade unmanned aerial vehicle, which belongs to the technical field of unmanned aerial vehicles. Background technique [0002] In recent years, light and small unmanned aerial vehicles have developed rapidly. But at present, the light and small rotor unmanned aerial vehicles are mostly based on single-rotor traditional layout helicopters. Although the single-rotor UAV with traditional layout has the advantages of long endurance and large load, its operation is difficult, its structure is complex, and the channels are coupled with each other, which makes the design and implementation of the controller difficult to achieve low-cost popularization. [0003] In the recent stage, battery technology and brushless DC motor drive technology have been very advanced. Taking advantage of the coaxial dual-rotor reverse rotation to eliminate torque, with the help of battery technology and DC motor drive technology, ...
