Marty_d Posted March 21, 2014 Share Posted March 21, 2014 Looks damn impressive to me, although that may just be the pretty graphics and 3D CAD renderings. Link to comment Share on other sites More sharing options...
farri Posted March 21, 2014 Share Posted March 21, 2014 Thanks Marty! Impressive it is but will it ever make it to the market place? Frank. Link to comment Share on other sites More sharing options...
Marty_d Posted March 21, 2014 Author Share Posted March 21, 2014 Don't know, but I like their stats... http://www.dukeengines.com/application/aviation/ 103Hp at 3300 RPM on 2.0 litre engine weighing 46kg with no need for a gearbox, and the rotating engine partially cancels out gyroscopic effects. Plus it's got a nice cylindrical shape making it easier to cowl nicely! Link to comment Share on other sites More sharing options...
facthunter Posted March 21, 2014 Share Posted March 21, 2014 You will have to fit a radiator somewhere. It is designed like a swashplate variable output hydraulic pump. Nerv Link to comment Share on other sites More sharing options...
Marty_d Posted March 21, 2014 Author Share Posted March 21, 2014 True. Chin mounted radiator perhaps. I think the general idea is very clever though. Link to comment Share on other sites More sharing options...
Old Koreelah Posted March 21, 2014 Share Posted March 21, 2014 Why do we have two threads on this engine? http://www.recreationalflying.com/threads/the-duke-axial-engine.115231/ Link to comment Share on other sites More sharing options...
spacesailor Posted March 21, 2014 Share Posted March 21, 2014 But I missed how the head gasket fits, if the cylinders are moving. spacesailor Link to comment Share on other sites More sharing options...
Ultralights Posted March 21, 2014 Share Posted March 21, 2014 thats what im thinking, how do you keep the compression and combustion gas pressures in check with a moving cylinder and fixed head? Link to comment Share on other sites More sharing options...
Old Koreelah Posted March 21, 2014 Share Posted March 21, 2014 My Ducati had no head gaskets. Compression relied on a good overlap fit between head and barrel. Some of the sealing technology developed for Wankel rotaries might have been adapted to this engine. Link to comment Share on other sites More sharing options...
