| Helix Turbine Noise Assessment |
|
This document is a statement from Helix Wind's engineering department on the sound or decibel levels of the turbine at typical operating speeds.
Decibel is a unit of measure for expressing the relative intensity of sounds on a scale from zero for the average least perceptible sound to about 130.

| 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. |
