Elliptical nozzles: the shape of silence?

该项目旨在利用椭圆形喷嘴几何结构的气动声学特性来显著降低安装的喷嘴噪声。该项目预计将产生有关减少安装的喷气噪声的方法的新知识，这是航空航天行业的一个严重问题。监管限制阻碍了提高效率配置的实施，但仍然无法消除对公共健康的影响。预期结果包括一套优化喷嘴设计的工具，能够显著降低安装的喷嘴噪音。这将带来巨大的好处，因为喷气式飞机噪音对澳大利亚公众来说是一个严重的健康问题。该项目提供了一个在提高燃料效率的同时减少其影响的机会。

This project aims to leverage the aeroacoustic properties of elliptical nozzle geometries to significantly reduce installed jet noise. This project expects to generate new knowledge regarding methods to reduce installed jet noise, a serious problem for the aerospace industry. Regulatory constraints inhibit the implementation of efficiency-increasing configurations but still fail to eliminate public health impacts. Expected outcomes include a set of tools for optimizing nozzle designs capable of significantly reducing installed jet noise. This will provide significant benefits, as jet noise is a serious health issue for the Australian public. This project represents an opportunity to reduce its impact while improving fuel efficiency.
