Latest Patents

Erica Holden holds a patent for a "Variable dual spring blade root support for gas turbines." This invention is an adjustable blade root spring device designed for turbine blade fixation in turbomachinery. The device is strategically placed in a rotor disk cavity adjacent to the tip of a blade root, applying a radial outward force on the turbine blade to secure its position within the rotor disk. The design features a wave spring with integral end blocks, which is compressed by a bolt and a coil spring. As the wave spring is compressed, it increases in height, making contact with both the rotor disk and the turbine blade. The force exerted by the wave spring can be adjusted via the bolt, while the coil spring offers an increased compliance range. The oblong cross-sectional shape of the device prevents it from rotating in the space between the blade and the disk.
