Silencing the screech tone - noise suppression in supersonic jets

这项研究的重点是进一步加深对被称为尖叫的气动声学现象的基本力学的理解。根据这一更深入的理解，预计将开发一系列量身定做的控制机制，以减少或消除高速飞机发动机中的尖叫声影响。这项研究建立在现有专业知识和已建立的实验设施的基础上。除了对基本机理的更好理解，这项研究的预期结果是更有效的主动和被动流动控制装置，以减少超音速喷射噪声。

The focus of this research is to further develop understanding of the fundamental mechanics of the aeroacoustic phenomenon known as screech. From this deeper understanding a range of tailored control mechanisms are expected to be developed to reduce or eliminate the effects of screech in the engines of high-speed aircraft. The research builds on existing expertise and established experimental facilities. As well as an improved understanding of fundamental mechanism, the expected outcomes of the research are more efficient active and passive flow control devices for the reduction of supersonic jet noise.
