项目摘要

The global interest in small multi-rotor drones, unmanned aerial vehicles and remotely pilotedaircraft systems (RPAS) is growing rapidly. It is now widely accepted that noise is one of the mainfactors that could limit the public acceptance and adoption of drones. Drones are currently designedfor performance, with relatively little consideration given to noise.This 3.5 year PhD studentship aimed at an experimental and analytical investigation into the effecton single-propeller noise due to its installation. It is well known that the noise due to propellersoperating in the vicinity of solid objects, such as wings, booms and other propellers, can besignificantly modified and amplified. The tones and broadband noise are known to be highly sensitiveto the degree of in-flow distortion caused by these objects.In this project, extensive noise and aerodynamic measurements will be performed using the thrustand torque load cells integrated into the propeller main body. A systematic parametric study will beperformed aimed at assessing the sensitivity on both tonal and broadband noise to the nearbystructures such as the boom or an aerofoil. Extensive pressure measurements will be made on thesurface of the boom to quantify the relative contribution of noise due to the obstacle and that fromthe propeller. Current analytical models will be extended to capture these installation effects.

全球对小型多旋翼无人机、无人驾驶航空器和遥控飞机系统的兴趣正在迅速增长。现在人们普遍认为，噪音是可能限制公众接受和采用无人机的主要因素之一。目前，无人机的设计主要是为了提高性能，而对噪音的考虑相对较少。这项为期3.5年的博士研究旨在通过实验和分析研究来研究其安装对单螺旋桨噪音的影响。众所周知，由于螺旋桨在固体物体（如机翼、吊杆和其他螺旋桨）附近工作而产生的噪声可以被显著地修改和放大。众所周知，音调和宽带噪声对这些物体引起的入流畸变程度非常敏感。在本项目中，将使用集成到螺旋桨主体中的推力和扭矩测压元件进行广泛的噪声和空气动力测量。将进行系统的参数研究，旨在评估音调和宽带噪声对附近结构（如吊杆或机翼）的敏感性。将在吊杆表面进行广泛的压力测量，以量化障碍物和螺旋桨噪声的相对贡献。目前的分析模型将被扩展，以捕捉这些安装效果。
