Wind Harvest’s VAWT-Bird Collision Calculator

WHI commissioned UCD engineer Matt Wylder to take the Scottish Natural Heritage model for calculating bird strikes in HAWTs and redo it for VAWTs. His paper “Vertical Axis Wind Turbines and Birds: Calculating a Theoretical Collision Risk Assuming No Avoiding Action” summarizes a number of runs he made using the VAWT collision model he developed. We welcome people to use and improve upon this tool.
