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.

该提案汇集了空气声学，空气动力学和飞行车辆设计的专家，以直接解决这一主要差距，以理解旨在实现高效且安静的未来多转机推进系统的设计和开发。该提案描述了最先进的设施中的详细流动和噪声测量值，以对重叠的螺旋桨系统的空气动力学和空气声学有基本的了解。高保真流和噪声数据将用于建立新的设计原理和高效率低噪声多旋转配置的半分析预测模型。在项目的最后阶段，该项目的结果将被利用，以开发全面的低噪声多旋转演示器。
