Twisted Savonius Wind Turbine Full Geometric Model (without traces/surfaces)

The Twisted Savonius Wind Turbine has promising applications for rooftop usage, but its high cost has kept it unfeasible for widespread adoption. The Twisted Savonius Geometric Modeling project explored the geometric properties of the turbine's shape, and proposed a more efficient method of construction and geometric design as a result. This is the complete side view "3d" model of the turbine. It models an extremely 3-dimensional shape by using ellipses to represent tilted circles. Changing X changes the rotation of the turbine (in operation). Theta represents the twist angle between the top and the bottom of the turbine. T controls the parametric location of the vertical surface - tracing it "fills in" the blade's surface. Learn more about this side view model.

September Problem

The radii of the small circles add up to that of the large circle. Why?

Announcing Mechanical Expressions!

We’ve just released a new program, Mechanical Expressions. It builds off of Geometry Expressions’ base, adding mechanics inputs and outputs. Its html5/Javascript app exports support dynamic simulations, so keep your eyes open for some popping up here on Euclid’s Muse. For more information about Mechanical Expressions, check out the website: http://mechanicalexpressions.com/.
