This was the very first paper I published in @ASA_JASA from my M.S. work. We studied global active noise control of a small axial fan and figured out mic placement to cause large sound power reductions.

Why does the Falcon-9 booster make a triple sonic boom?

New research by myself and @KentLGee explains why this happens! Go check it out!

https://t.co/UYYVa6uoZb

Here are the three shocks:

1. Comes from the bottom of the booster near the engines. All supersonic objects make a front (or “bow”) shock. Because the rocket is falling engines first, the engine section is considered the front of the vehicle.

2. Comes from a combination of a rarefaction wave produced near the bottom of the booster (including, but not limited to, the folded landing legs) and a compression wave produced by the extended grid fins. These two waves merge and form a single shock in the middle of the sonic boom (actually, about 2/3 of the way through the boom in measurements).

3. Comes from just behind the top of the booster, where the air returns to ambient.

If you like science like this and want to support this type of research, go ahead and open the link and download the paper. That helps show that people are interested! Rockets are awesome!

Also thankful to @BYU and @BYU_PhysAstro, along with other sponsors and our friend @LaunchPhoto who let us use his photograph, for enabling this research!
