    Air-breathing spin detonation ramjet, video of test and link to website.

    PS, lots of other VERY interesting projects on that website, from liquid breathing apparatuses to super polymers to new forms of 3d printing, ooh la la.

    So is this a scramjet minus the waverider design? Then again it looks like it could be the lower portion of the Kh-90 design:

    It could be, TKMDB Soyuz was supposed to make the engine for Kh-90 and they're the same people behind this, but I mainly wanted to point out the spin detonation part of this engine, I'm not aware of any other project in the world at this size and power, really pointing to Russia's leadership in this.

    This plus the kerosene and liquid oxygen detonation engine shown a while ago bodes quite well for the Aerospace industry. I wonder if their will be a detonation engine for subsonic aircraft or if that will be handled by HTSC electric motors that are being made with SuperOx.

    What would be the actual advantage? It couldn't be speed (subsonic obviously), could it be range? The Foundation for Advanced Studies has promising advanced prototypes of electric engines for aircraft, and considering the Federation has the most cost-competitive Graphene production (apparently by a factor of 75).

    If they 3D print Li-ion batteries made from Graphene, combined the electric engines, it should make a real impact on the world of aeronautics....especially because the 737 Max has caused Boeings shares to nose dive, and the current pandemic has put commercial airliner industry in to the shitter!

    Well, detonation engines make their distinction as being detonation rather than deflagration, which is outright more efficient and more powerful, nothing says you couldn't make one for subsonic usage or even turboshaft setup like for powering helos, ground vehicles, ships and other things and there are concepts and programs for exactly such engines.


    And yes, Russia's advantage in graphene and other material sciences will be the winning factor in the future arms/tech race going on, but with regards to electric aircraft I don't see fully electric widebodies coming soon, requirements are too severe for even future battery concepts, current trend for larger electric aircraft compared to the ones we have now is a electric drive setup, with a turbine powering a generator and then using that for an electric motor, which is where SuperOx's HTSC tech comes in, and where a detonation shaft engine with far superior characteristics come in(lighter, smaller, more powerful, less fuel usage) make it another winner for something like CR929, or another potential widebody from Russia.

    There was a Sukhoi paper project with partial folding wings and a double decker setup that didn't go anywhere to the glorious 90s and general expense of the project. It was called KR-860 and looks stunning. With future detonation engines and HTSC, along with new super materials coming along, such as graphene and super polymers/composites that are being worked on, you might see Russia going on it's own for a widebody without China holding it back. I honestly feel that CR929 is just a guaranteed way of making money of Chinese market.

    Jet engines are pretty standard on most subsonic large aircraft like airliners and cargo transport planes... a more efficient much cheaper simpler engine design is always interesting and potentially useful... and of course if this offers potential for scramjet propulsion having an engine type that can operate from a standing still start to mach 20 plus in the high atmosphere would mean the goal of an aircraft that could take off from a runway and accelerate fast enough to launch a satellite into orbit could be achieved...

    Currently you need a significant rocket from something like a MiG-31 to get something in to low earth orbit but imagine an aircraft that climbed to 60km altitude at mach 20... you are well above most of the atmosphere so a rocket could then take a sizable payload into low earth orbit or a smaller payload to a much higher orbit without needing to be enormous and therefore expensive...

    That plane could also deliver things around the world at astounding speeds... whether it is humans or critical cargo.... imagine a 3 hour flight from London to Sydney...
