Abstract

Engineered spectral response turbine coatings are designed for insect repulsion in an environmentally visually unobtrusive manner for increased turbine annual energy production (AEP). The engineered spectral response of paint repels insects and is acceptable from a human perception point of view. The paint uses properties of the infrared (IR) and ultraviolet (UV) spectrums that are detectable by insects but not humans. The design patterns of the coatings are stripes or spots. Thermal impacts of coatings, such as, heat absorption properties which are known to be relevant with respect to mosquitoes are also considered.

DETAILED DESCRIPTION

In areas having a large population of insects, large masses of insects may be deposited on air foils of wind turbines. By painting air foils with colors which are less attractive to insects, insect concentration in the vicinity of the airfoil may be reduced, and of the amount of deposited insects on the air foils may correspondingly be reduced. The leading edge of an air foil is a particularly sensitive area for aerodynamic performance and therefore affects annual energy production (AEP).

An earlier des study of relative attraction of specific turbine colors and other hues was done to determine if turbine paint color influences insect numbers. The common turbine colors, such as pure white and light grey, were found to attract significantly more insects than other colors tested.

A flow-visualization technique was used to analyze airflow separation over the blades, determine whether insects are present in undesirable amount, and, if so, clean the blades.

There is a need in the art for an efficient technique to assess coatings for wind turbines.

The engineered spectral response turbine coatings disclosed herein are designed for insect repulsion in an environmentally visually unobtrusive manner for increased turbine annual energy production (AEP). The engineered sp...
