Abstract
U.S. Windpower (USW) and the National Renewable Energy Laboratory (NREL) are conducting a comprehensive cooperative test program to perform full-scale blade tests at NREL's Structural Test Facility (STF) under a Cooperative Research and Development Agreement (CRADA). During Phase I of the CRADA, photoelastic measurements, modal analysis, and load-to-failure destructive tests were conducted on USW 56-100 blades. These tests will measure a variety of blade characteristics including the strain fields at critical blade areas, dynamic blade properties, and ultimate blade strength. Information from this testing will be used to help USW better understand the blades' structural properties and to help quantify blade strength degradation with time and loading during normal operation. NREL will use this information to develop improved methods for testing wind turbine blades.
