Simple Steam Turbine
by matrhint, published
This is a simple three stage steam engine design that I hope to cast in aluminum sometime in the future. The design was based from the book "Model Steam Engines: How to Design and Build Them."
Print the parts out, construct the turbine (the top and bottom case parts can be hot-glued/heat gunned together, but I added some tabs so they can be tapped on the aluminum version), and then test it out (it should work with breath or compressed air).
