The Simple Stirling 1 Plans are done !
May 19, 2008 – 12:45 amThe plans all drawn up. You can see a 3D pdf model that gives you the ability to look at every single part from any angle. If you haven’t used this Adobe 3D view make sure to try both mouse buttons and the mouse wheel for navigating the drawing. There is a directory tree that lets you highlight parts or hide them. I’ve put up a second page that has a sample drawing for one of the parts. I’ll be getting the remainder of the drawings up in the next few days plus some directions on building the engine.

Beautiful work – Thanks.
An observation – since you have to extract power in quadrature – and the power is extracted over what appears to be an elliptical curve, perhaps a mechanical coupling that mimics a pantograph that would produce the desired ellipse, would allow a better match and increase the coupling efficiency. (this is from an EE, not an ME … so take it for what it’s worth
)
Other Ideas –
1. a transmission made of a cone and a wheel off axis to each other
2. a transmission made of two cones, off axis to each other
3. a planetary gearing system.
I would like to know if these ideas are useful.

On my engine 3D I think I am using what you refer to as a pantograph-type coupling (see http://www.solarheatengines.com/photos/engine-3-photos/img_1836/ ) For the simple engine I’m avoiding as much complexity as possible. For an elegant solution the rhombic drive (see http://en.wikipedia.org/wiki/Rhombic_drive ) is hard to beat–but it isn’t simple to make. Feel free to apply your creative energy to developing a simple mechanism to closely approximate the ideal Stirling cycle (see http://www.solarheatengines.com/2008/05/07/the-stirling-cycle%e2%80%94ideal-and-practical/ )
