Hello Friends, I finally finished my radial engine model and renders. Of course most of you will recognize this engine as the Karl-Erik Olsryd 9-cylinder quarter scale model of the Wright J-5 Whirlwind. I modeled it from the drawings by Jan Elg, deviating a bit from the drawings only when I felt it would benefit form or function.

The Solidworks 2013 model is complete with all Mechanical Mates. You can turn the propeller and and see all the workings of the complete valve train, intake blower, gear box, distributor, planetary gears, etc. One exception is the valve springs. I have included them in the model but Solidworks could not handle the additional dynamics of 18 functioning valve springs.

Credits: The model is mine complete with the exception of the carbureator and propeller. Credit for the carbureator goes to Jan Elg and the propeller is from Grabcad user Usama. Thanks to both.

I'm uploading my complete Solidworks 2013 files, parts & assemblies, as well as STEP, IGES, STL and several high resolution renderings I created with Bunkspeed Shot. Click the Download button to see them in Hi-Res glory!
