7:20 The space shuttle's ceramic tiles were not ablative. Ceramic tiles in general are not ablavive, though they may erode with repeated use. ablative heat shields are generally not reuseble and are usually made of a polymer resin.
If a propeller spins fast enough it's possible that the wing tip break the sound barrier. I wonder if it's possible to build an engine on this principle. It would consist of a spinning disk with openings to allow supersonic airflow to enter the inlet. Combustion would create thrust and keep it spinning. I would angle it slightly so that the intake isn't sucking in exhaust and a portion of the exhaust can create thrust
There have been some designs with supersonic tip speeds, but usually they create such loud noises that it knocks out the ground crew. It also introduces instabilities in the propeller and huge loadings.
@@PremierAerodynamics getting it to spin at mach 3 without tearing itself to shreds probably isn't possible with current materials either unfortunately
@@PremierAerodynamics another idea I do have though as far as normal turbine engines go is having canular combustion chambers mounted on the shaft angled at 45°. That does away with the need for turbine blades which means you can run the engine as hot as you please. Also reduces weight and cost

Ah, you're right. For some reason I thought the leading edge tiles were ablative. Thanks for the correction!
As someone looking to eventually specialize in hypersonics I found this video to be amazing! Keep up the good work 🙏
Thanks! Happy you liked it!
Remember, you can't spell Hypersonic without ype.
i love how this chanel is growing bigger and better every time i see it
Likewise 🤝
Thank you so much! Happy that you like it and that it is growing too.
Thank you!
I am *shocked* that laminar flow is even possible in supersonic flow, given it has to travel through shockwaves even before the boundary layer begins.
Hypersonic and supersonic flows are wacky!
@@PremierAerodynamics yes absolutely, I've been learning aerodynamics on my own the last couple of years but I stay faaaar away from that stuff
