MODERATORS
Yup
This article is bullshit: they're reporting that a blueprint was made. No demonstration, no proof of it working.
Rotary detonation isn't a new concept and GE has demonstrated a rotary detonation scramjet for 0 - Mach 5.
If you really think that 0 to Mach 16 is within reach with current technology RDEs I have a bridge to sell you.
Darpa has all the money of God and they've been throwing billions at the exact problem of rotary detonation. Everybody knows that detonation is more fuel efficient than deflagration and that turbine engines are holding jet aircraft back from hypersonic flight.
When they make a Mach 16 demonstrator I'll believe them. Until then I'm still very excited for the demonstrated and actual capabilities of RDE Scramjets.
That's nice...
...when I see it in production.
Yeah, no. Just no. Absolutely no. Faster than everything else.and higher than everything else and all of that by burning less energy? Come on people, stop falling for this kind of crap.
I'll wait until other countries validate the findings, or until someone makes a working prototype, before getting excited. Seems like it's one of those "too good to be true" stories like the LK-99. Hype in tech and science almost always leads to disappointment.
If that engine actually works, it would be cool to see it on a space plane. Mach 16 is nearly 2/3rds of orbital velocity. If you could go that fast on an air breathing engine, you wouldn't need to carry nearly as much oxygen to get into LEO.
I imagine that theoretical speed could only be used for drone planes.
You could ride on it, but you’d need a cowboy hat.
If a space suit is needed, would the hat go inside or outside the suit?
it pokes through like a space marines pony tail
Outside, why wear a hat if no one can see it ?
Aerodynamics.
That's why cowboy hats have folded brims.
I imagine you would need a cowboy hat that would also supply oxygen.
