Latest Patents

Sandy holds a patent for a "Base excitation testing system using spring elements to pivotally mount wind turbine blades." This system is designed for fatigue testing wind turbine blades through forced or resonant excitation of the base of a blade. The system includes a test stand and a restoring spring assembly mounted on the test stand. The restoring spring assembly features a primary spring element that extends outward from the test stand to a blade mounting plate configured to receive the base of the blade. During fatigue testing, a supported base of a blade may be pivotally mounted to the test stand via the restoring spring assembly. The system may also include an excitation input assembly that is interconnected with the blade mounting plate to selectively apply flapwise, edgewise, and/or pitch excitation forces. Additionally, the restoring spring assembly may include at least one tuning spring member positioned adjacent to the primary spring element to tune the spring constant or stiffness of the primary spring element in one of the excitation directions. Sandy has 1 patent to her name.
