Abstract
A platform for a turbomachine is fitted to a variable-setting stator blade to repair a worn area on a plate of the blade. The worn area may be caused by contact between the plate and a part of a casing during operation of the turbomachine. The plate may be machined before the platform may be properly fitted to the plate. The platform may include an anti-rotation tab to prevent the platform from rotating relative to an axis of rotation of a pivot of the blade. The platform may also include a collar to cover an outer diameter of the plate. After the platform has been fitted to the plate, the case may contact the platform instead of the plate.
