Project overview

This project aims to improve the safety of rocket launches by predicting and ultimately controlling the intense sound waves generated by a rocket’s exhaust. These sound waves are so loud they can damage the structure of the rocket, leading to catastrophic failure on the launchpad. In some cases, the sound becomes amplified by a feedback loop, making it even more dangerous.

By better understanding the source of these soundwaves and feedback loops, this project will facilitate the design of safer, more reliable, and more efficient rocket nozzles. The project will also develop Australian capability in an important component of space launch, via a small-scale launch testing facility suitable for the Australian context. These developments will benefit Australia through the embedding of links with major space agencies and will enhance the competitiveness of the emerging Australian space industry.
