9:00 will get you past a lot of defense, etc. crappola.

Extend the centre into an aerospike and you are golden.

[@-danR]

Aerospikes always lead to a dead end.

@@-danR so do rde's, the 2 are perfect for eachother

[@173muppet]

Aerospikes have trouble cooling the spike and preventing it from warping and melting. This problem would be amplified by the heat issues posed by detonation waves.

why no turbopump required? they have to mix them. how coling is going? how generate more thrust? can i see the wave propagation? i mean from explosion to the next detonation. to see how that waves expand in to the chamber.

[@craighalpin1917]

From what I understand detonation produces a compression ratio x1000 where as conventional jet turbines produce compression ratio in the x100... producing much higher efficiencies reducing your need for the volume of fuel air mixture as compared to conventional jet turbines.

@@craighalpin1917 nice info but i dont ask that. I ask how that compresion it expand. because circle have 3 why to go. Sides, backward and forward and outside(let say up). The thurst is generat when is go all that compresion "x1000" or "x100" Up. And if go frontward it help the next detonation get more compresion, but if go back ward (counterclockwise) it lose compresion.

[@craighalpin1917]

@Proto_HeXagon I believe the wave moves across/around the circular chamber and out forming an angle... The angle Shown at 21:25... Maybe close to 45°. The expansion will mostly occur once the gasses exit the chamber, they told us in the video that there was no nozzle equiped on this engine. If and when the detonation wave moves in reverse I think it causes the engine to become less efficient but it still operates. It's clear that the engine would operate better when the wave moves in a single direction around the circle and this is what I believe one of the major engineering challenges they are trying to overcome, wave stability.

this is exciting

[@thomasciarlariello3228]

Similar to how late 1960s Lockwood had Patented a valveless pulsejet engine or blast wave engine and how Frank Rom from late 1960s to early 1970s Patented uranium gas core fission fragment rocket engines essential for orbital launch since a vintage brute force mentality of semi disposable multistage vertical flight into orbit by chemical reactions cannot meet future needs.

Show us how THRUST results from all this wizardry.

[@jeravincer]

1st!

[@bussi7859]

Just Blablablablabla, no results what so ever
