Elliptical nozzles: the shape of silence?

该项目旨在利用椭圆喷嘴几何形状的气动声学特性来显著降低安装的射流噪声。该项目希望产生新的知识，以减少安装的喷气机噪音，这是航空航天工业的一个严重问题。监管限制限制了提高效率配置的实施，但仍未能消除对公共卫生的影响。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射流噪声。这将带来巨大的好处，因为飞机噪音对澳大利亚公众来说是一个严重的健康问题。该项目提供了一个机会，在提高燃油效率的同时减少其影响。

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.
