This proposal brings together specialists in aeroacoustics, aerodynamics and flight vehicle design to address directly this major gap in understanding aimed at enabling the design and development of efficient and quiet future multi-rotor propulsion systems. This proposal describes detailed flow and noise measurements in state-of-the-art facilities to gain a fundamental understanding into the aerodynamics and aeroacoustics of overlapping propeller systems. High fidelity flow and noise data will be used to establish new design principles and semi-analytical predictive models for high-efficiency low-noise multi-rotor configurations. In the final phase of the project the results from the project will be exploited to develop a full-scale low-noise multi-rotor demonstrator.

这项提议汇集了空气声学、空气动力学和飞行器设计方面的专家，以直接解决这一重大的理解差距，旨在使设计和开发高效和安静的未来多旋翼推进系统成为可能。本建议描述了在最先进的设施中进行详细的流动和噪声测量，以获得对重叠螺旋桨系统的空气动力学和空气声学的基本了解。高保真流动和噪声数据将用于建立高效、低噪声多转子构型的新设计原则和半解析预测模型。在该项目的最后阶段，将利用该项目的成果开发一台全尺寸低噪声多转子演示机。
