and all those o-rings, looks like a nightmare of sealing issues. tension bolts are also too far towards the outside of the block which probably caused issues sealing the housings for any level of performance.
the one nice thing about the design is a failed inner seal wouldn't cause overheating/cooling pressurization issues for more limpability.
and yes, i bet the long block weighs in at a mere 500lbs.... but it is interesting seeing a rotary engine in a FWD format.

lol, those rotors also look very similar to mazda's down to the oil ribs and location of everything on the rotors, except the balancing mill locations are more centralized than aimed at the apex of the rotor.
i wonder if they treated the irons or just accepted a 30k mile life expectancy.

although it does seem like what happens in russia stays in russia, so who knows?

sounds like the russian engines were caught up with where mazda was when they introduced the rotary in the late 60's with carbon apex seals. equally bad ideas, at least mazda persevered but i feel sorry for anyone who bought one of those early contraptions they actually called an engine. the early owners were the guinea pigs who paid for mazda to re-engineer the actual engine we still use today.

I have a secret obsession with soviet era technology and engineering, they always seem to reinvent proven designs in the most obtuse and ghetto rigged ways. What really makes it intriguing is most of the time their craziness works. If that doesn't work out, they being communists will just copy some one elses design down to the last 1/100,000 of an inch. I'm surprised they just didn't clone a bunch of mazda units, but alas that's what made the USSR what it was.
Example of soviet R&D process
Soviet military: We need a sea fairing ship that is faster then any allied ship, oh yeah it has to be big too, maybe you guys can design a more powerful ship engine?
Soviet engineer: A more powerful engine?!? that's kinda stupid, no obviously the problem is not the glorious military cargo ship of the people, it is the water keeps it from going fast, we need to take the sea out of the whole ship equation!
Soviet military: That makes absolute perfect sense
Soviet engineer: well duh! oh btw here I designed this on my napkin during our conversation
Soviet military: I like it, but it seems kinda crazy, and this boat is still touching the water and we don't want that, got any thing else?
soviet engineer: sure how about this, this boat cruises about 550 km/h at 5 meters above the surface of the water, I even drew in some cool missle lauchers on the roof!
Soviet military: OMG! best boat ever! America is going to be sooooooo jealous!
A little while later.......
Wait a second, I asked for a better ship engine to retrofit our old fleet, how the hell did that lead to building planes that can't fly above land!?!?!

i can't envision russia being the first to implement an internal clocking mechanism for that engine, at least not a reliable one.
it does look good on paper having 4 firing chambers per revolution in a small package, but keep in mind it probably took them 20 years to even make that video... another 20 years from now you may see a working model which still will need plenty of revision to be a reliable powerplant.
sorry, but i am not seeing this coming from russia and it is no offense to their people. if they could convince the germans to do it then you might see something workable within the decade. to me that video just looks like a pipe dream someone thought up, a spherical radiused firing chamber is going to wear rapidly and also not seal very well(heat causes expansion, RPMs cause expansion also so you have 2 forces working against that outer wall not even counting friction from the seals required), but that is about par for the course. the best application for it would be based off a set RPM as say a generator where the engine can be designed for the purpose, it will simply not work well for a varying RPM powerplant.
diesel trains and some boats use a similar concept with opposing pistons sharing a single firing sequence. basically you have an engine on top facing down and an engine on the bottom facing up, 2 pistons compress in the center. even that ancient technology is still ahead of this.
also keep in mind the clocking mechanism is going to absorb more power from the engine, reducing it's efficiency already making this idea obsolete.
i have a better idea, there's a huge power source above us every day in the form of a red ball of fire in the sky which has an abundance of unharnessed energy pelted at us for 2/3 of our waking hours. but what do i know, i should be sitting at a computer making up designs like this, trying to find people to fund stupid ****....
i liked this thread more before seeing that video

I hear you Karack, I just wanted to see what kind of feed back this would get only because I was a bit impressed with that idea. By the way I tipped back quite a few before the Cotto Mayweather fight and even more after because I lost a good chunk of cash LOL.

What about these guys...?
http://www.freedom-motors.com/
2- and 3-rotors
They claim they can go to 9 rotors.
