What is it about?
When you throttle a hypersonic inlet, the buzz-frequency varies. Is there a simple way to predict this buzz frequency for a variety of inlet mach number and throttling conditions? There is a way, and in this paper, we have tried to explain.

Why is it important?
Current hypersonic vehicle design needs the characteristic large-scale frequency to develop a proper structural frame-work. The findings from the present study will help in arriving at it easily through simple correlations.
Perspectives
With my fellow researchers, it was an amazing opportunity to collaborate and write this article. Especially during the pandemic, the simulations were run in one place and analyses were carried out across the country. The data flow organization, communication, and the final drawn conclusions were all carefully discussed. Thanks to modern-day systems and online platforms which helped in streamlining the process. I believe we have made a significant contribution to the community.
