Sorry, I’m still not seeing how the compression is achieved without the compressor stage fans. A Blended Wing Body (BWB) architecture may be easier to engineer for mach 24…

BWB is even-more like the manta ray shape, true.

Well, SR-71 design is clear, but tops out at about Mach 3.2. How’s compression achieved in existing scramjet designs?
Isn’t this done by manipulation of shock waves?

By the way, this book has a section on scramjets, that mentions how electricity assists present designs:

What we need right now is a team of Maxwell’s demons, to open the window for particles traveling in preferred directions only. 😉

I’m brainstorming, that the doppler effect will help: the emitters will be carefully tuned and focused, so that particles moving the wrong way through the engine are slowed, and particles moving the right way are accelerated.

Oh, and I like vortices, too. If we use them, then this should be a twin-engine design, for stability.
