摘要:

為了提高多旋翼無(wú)人機氣象探測的準確度,基于CFD方法對偶數槳旋翼無(wú)人機的流場(chǎng)進(jìn)行分析,比較了不同旋翼數和不同旋翼間距離的無(wú)人機的流場(chǎng),分析了流場(chǎng)的特點(diǎn)。同時(shí),結合大氣探測設備對溫濕度、氣體濃度及顆粒物濃度測量的基本原理,分析了多旋翼無(wú)人機擾流場(chǎng)對探測設備測量精度的影響及其原因。由此確定了進(jìn)行大氣探測的多旋翼無(wú)人機盡量根據情況選擇旋翼數較多、翼間距較大的機型,探測設備安裝位置應當靠近無(wú)人機中心軸靠近旋翼旋轉平面處的相對靜風(fēng)區,經(jīng)實(shí)驗對比,通過(guò)優(yōu)化可以有效減小測量的誤差。并提出可利用多旋翼無(wú)人機流場(chǎng)特點(diǎn)設計多旋翼無(wú)人機專(zhuān)用探測設備的構想。

Abstract:

In order to improve the accuracy of multi-rotor UAV meteorological detection, CFD method is used to analyze the flow field of even-rotor unmanned aerial vehicle (UAV). The flow field of UAVs with different rotor numbers and distance between different rotors is compared. The characteristics of the flow field are analyzed. At the same time, the influence of the multi - rotor UAV on the measurement accuracy of the detection equipment is analyzed based on the basic principle of temperature and humidity, gas concentration and particle concentration measurement. It is determined that the multi-rotor unmanned aerial vehicle (UAV) for atmospheric detection should choose the number of rotors with large number of windings as far as possible. The installation position of the detection equipment should be close to the relative static wind at the axis of rotation of the unmanned aerial vehicle Area, by experimentation, through optimization can effectively reduce the measurement error. And put forward the idea of using the multi-rotor unmanned aerial vehicle flow field in the future to design the multi-rotor unmanned aerial vehicle special detection equipment.
