Thought I'd post an informative video about the RevolverCam or "DynaCam" engine. One of the most highly developed and tested axial engine designs. It's pretty neat!

That was really cool. Thanks for sharing.

Also, from the recommended videos links off that... Holy mother of WTF!

That last engine would shake itself to bits. He only balanced the rotational mass about the axis of rotation... The angular vibrations along the axes perpendicular to rotation are free to go about their business unabated.

I know, its like he thinks the air-spring of the split-compression cycle is going to magically make up for the mass of the piston!

Watching the animation again, it DOES have a hearty counter-weight on the flywheel, but there would still be all kinds of side-loading on that complex, compound bearing...

But wouldn't the 6 hydrocoptic marzel vanes so fitted to the amberficient lunar wayne-shaft effectively prevent side fumbling?

only if the turbo encabulator has been correctly serviced.

The counterweight on the flywheel balances the straight line vibrations, which is good. You need that in an engine. But you also need to make sure it doesn't vibrate angularly. As the pistons go back and forth, they will try to rotate the entire engine by way of conservation of angular momentum. Those masses need to be balanced equally on the opposite side of the center of mass of the engine.

ah, yes, if he had tweaked the crank shaft so that each member of the group of piston pairs was 180° out it would smooth right out...

Of course, that would then require longer transfer ports for the split-cycle compression... Yeah, that thing is fun to look at, but as a functional engine idea, its kinda a mess.
