Solar Turbines Incorporated sponsored a team of three Cal Poly Undergraduate Mechanical Engineering students to design, manufacture, prototype, and test a tool for the removal of turbine blades from their respective disk assembly without damaging the disk itself. The tool was developed for Solar’s industrial gas turbine engines. The tool complies with all OSHA and Solar Turbines safety and engineering constraints, and was designed for use in a shop facility. The tool was made adaptable for geometric variances in multiple turbine rotor disk stages, and requires no more than one technician to operate using a maximum of two shop resources. The tool stands alone on its own fixture, with ease of portability and disassembly in mind. A discrete process was developed to assist in the transition from the current blade removal process to the new blade removal process. In doing so, future disk damage can be prevented by developing a tool and process used to replace the current rudimentary techniques for blade removal.
