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.

Turbine Optimization for Urban Applications

This illustration demonstrates the suggested placement of turbines in a urban or city setting and the turbulence characteristics of a building in relation to a prevailing wind pattern.

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

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.
