无人机共轴双旋翼气动特性分析

Analysis on the Aerodynamic Characteristics of the Coaxial Twin Rotors of the UAV

航拍无人机作为一种新式无人机,通常由多旋翼无人机机架、飞行控制系统、推进系统、遥控器、接收机和云台组成。本文针对航拍无人机的推进系统研究分析,主要研究了航拍无人机共轴双旋翼装置的气动特性,利用CFD对推进系统进行模拟,采用动量叶素理论分析共轴双旋翼推进装置上下旋翼的气动特性,对装置实际运用优化改进有着重要意义。

As a new type of drone,aerial drone usually consists of a multi-rotor drone frame,a flight control system,a propulsion system,a remote controller,a receiver and a gimbal.This article focuses on the research and analysis of the propulsion system of aerial drones,mainly studies the aerodynamic characteristics of the aerial UAV′s coaxial two-rotor device,simulates the propulsion system with cfd,and analyzes the aerodynamic characteristics of the upper and lower rotors of the coaxial two-rotor propulsion device by using the momentum blade theory,which is of great significance to the optimization and improvement of the actual application of the device.
