Badland Part 103 Pilots and Builders Forum

Lots of great ideas for engines and this one is in line with the rest - great idea, but will it work? This engine is very light (is titanium), very small for the amount of power produced and might be the future of ICE design. The one big difference the engineers of this company have over just about every other new engine design I've seen is, they actually have a prototype run at the end of this video. It's not a long run, but does show that the engine does in fact run.

Looking at how it runs I have a concern about carbon buildup in the expanding combustion chamber. The top roller and bottom roller (the one that contains the combustion cup) simply rotate around on each other. What happens when buildup accumulates on the top and bottom rollers? Is there a scraper that cleans this off as the roller is rotating? Even a very clean fuel will have some sort of carbon buildup.

I'm sure there are technical engineering problems with this engine. So the question is, can those issues be overcome? Wait and see.
