The turbine blade test cascade consisting of a tertiary gas clean-up system and a channel for blading has been installed and commissioned using a dummy channel without blades at the Grimethorpe Experimental Facility. The cascade unit was designed to allow the testing of a variety of materials used in commerical gas turbines and to evaluate the nature and extent of corrosion, erosion and deposition on aerofoil-shaped specimens, dimensionally scaled to represent first stage rotor blades. The report details the process and mechanical designs of the cascade system and provides a description of the installation and commissioning activities. The operating experience gained during the commissioning phase highlighted several areas where modifications could be undertaken to improve performance, and these modifications are discussed.
