New Alternate Engine ???

[RV6_flyer]

Van is smarter than I am so I follow his recommendation on engines for RVs.

I know there are many people that do not like to follow recommendations of successful designers.

Here is something I found in a car forum that I read. Talk about a NEW design that has potential. Wow!

The MYT™ (Massive Yet Tiny) Engine

I know it is too light weight and too much HP for an RV.

Great idea, great design. It would be even better if they had a running model.

I see in this video http://www.youtube.com/watch?v=kGlUZg2pC0Q&NR=1 that Raphial is talking about scaling the engine for lower horsepower (200 hp was mentioned). C of G issues would still need to be resolved for application to existing light aircraft designs. A whole new aircraft designed around this engine would be very interesting to see. I'm guessing you would also see some pretty unusual propeller designs to take advantage of the torque output, as well. I'm curious as to what kind of power pulse and vibration characteristics this engine might have at direct drive operating RPM's.

Seconded. Looks like a cool concept, but I'm sceptical about the numbers. I'm calling shenanigans until I see one running.

I like the concept, it may be very workable, but I've got more questions than answers. I don't see any real detail on the site at all - it appears the two rotating vane sets are in a TV-like mode with respect to each other, driven by pressure pulses. I'd like to know how they are entrained to maintain that motion, how do they couple power to the crankshaft, how do they seal to the face (outside edge) of the chamber as they rotate.

Also, from the animation it's apparent that the combustion always takes place at the same two places on the outside radius of the case - those will be intense hot spots and cooling will be a very interesting animal to tame. With a round case and localized heating at opposed points, you'll oval out that case in a heartbeat, defeating a perfectly circular rotor(s), so a novel sealing system (or a kick-butt cooling system) is needed. The rotors will not be coolable by water jacket, so some heavy oil cooling from a ported crankshaft will be needed.

I like the concept - I want to see one run in a test cell.

How can they make all these claims without a functioning prototype?

I agree. But isn't this just a re-vitalized steam engine concept from way back?

You can claim anything you want but as the direction of this thread is taking your credibility is suspect until proved otherwise. Leonardo DaVinci's flying machine probably looked pretty impressive when first drawn up but we all know how well it couldn't fly. Our mechanisms have become so sophisticated a quantum improvement is difficult. I'm cheering for it anyway. Love to see innovation.

Speaking of credibility, here is a quote the inventor, Mr. Morgado:

"By replacing an 800 pound V-8 engine with a 25 pound MYT and running it on biodiesel, we can achieve 150 miles per gallon in an otherwise conventional vehicle -- plus, you're going to have better take-off and stopping power by removing that 800 pound engine. That's what we can do. It is achievable." - Raphial Morgado

I'm going to need a little convincing that an 800 cubic inch diesel will get 150 MPG in an SUV. He would have had my attention if he had just said something about the mileage improvement due to lower weigh of the powerplant. It is new "monkey motion" connected to what is a two-stroke diesel. It won't change the laws of thermodynamics. I am, however really interested is seeing how he seals the "slot" in the cylinder wall that connects the pistons to the system.

The concept is great and not being reciprocating should/would provide turbine link smoothness and high torque at low RPMs with piston efficiencies. The mechanics of "locking" the magenta "pistons" in place so that the combustion can react against the blue "pistons" would be the challenge.
