Engineering Summaries
The Savonious R1 and Savonious C2 Helix Wind turbines have undergone analysis of structural integrity when
subject to aerodynamic loading. The primary failure mode is bending of the shaft in both
models. Aerodynamic analysis of wind tunnel data was utilized to establish empirical CD
values.
