Default Rotary Engine Design

For some time I've been wanting to design a "steam" engine that runs like a WWI Gnome rotary (e.i. the crankshaft is stationary and the block rotates).

Several years ago I was partially successful with a two cylinder design. Anyways, I've become much more accomplished since then.

I've finished a design for a five cylinder version. In my CAD software, it looks like it all works out. I plan on building this this winter, but attached are the plans if anyone would want to review, improve, and/or build it.

I've deliberately left off material types because you can use whatever you feel looks good.

Great idea. I have had similar thoughts, my version was going to feed the air or steam from a ported back plate rather than through the crankshaft.

Thanks for sharing you work and ideas. Looks like a fun project

Mike

Thanks,

I'll actually start building it in early 2013. The progress will be shown here.

I have been looking at the drawings. Again thank you for sharing them.
I just see a hole through the crankshaft and assume that is the steam/air inlet. How does the engine exhaust?

Thanks
Mike

There is a port on each cylinder at the bottom of the piston stroke. The pistons are single acting and the engine is kind of a uniflow design.
