General Turbine Height Diagram

Scaled height comparisons of turbine systems on top of buildings and pole mountings in pedestrian areas.

Turbine Staggered Height Array

Description of turbine height array for side by side placements.  It is important to take into consideration the turbulence that each turbine will create and how it affects the placement of multiple turbines.  Each turbine needs clear airflow from each other from multiple directions.

Turbine Same Height Spacing Dimensions

Turbine spacing for ground or even surface same height installation dimensions. Spacing this way should be at 12 feet (3.65 m) or 3X the blade diameter to maximize possible power production efficiency

S322 Engineering Summary

The S322 Helix Wind turbine has undergone analysis of structural integrity when subject to aerodynamic loading. The primary failure mode is bending of the shaft.  Aerodynamic analysis of wind tunnel data was utilized to establish empirical CD values. REV F

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.
