This project aims to understand how acoustic loads are generated in supersonic combustion ramjets (scramjets) to control sonic fatigue in reusable hypersonic vehicles. This knowledge could make space access affordable. This project will measure acoustic waves in scramjets. The anticipated discoveries will enable reusable, hypersonic vehicles to be used for space launch systems and high-speed aircraft. These systems will dramatically reduce the cost of space launch and global travel times. Expected benefits include reduced cost for access to space and the ability to design and develop advanced aerospace technology.

该项目旨在了解超音速燃烧冲压发动机（超燃冲压发动机）如何产生声载荷，以控制可重复使用的高超声速飞行器的声疲劳。这些知识可以让人们负担得起太空旅行。这个项目将测量超燃冲压发动机的声波。预期的发现将使可重复使用的高超音速飞行器用于空间发射系统和高速飞机。这些系统将大大降低太空发射的成本和全球旅行的时间。预期的好处包括降低进入空间的成本以及设计和开发先进航空航天技术的能力。
