a little bit of eye candy with this little rotary steam engine. A few prototypes were build around 1900 by Ljungstroem.
This engine would produce approx 2BHP at 1500rpm and 7bar steam pressure. Piston diameter 40mm and size of the disk casing roughly 200mm.
Piston stroke is approx 21mm.
Little exercise for me to get accustomed to the placing, attaching and rotating of bodies in FreeCAD.
