Patent 8641377 was granted and assigned to Florida Turbine Technologies Inc. on February, 2014 by the United States Patent and Trademark Office.
A turbine rotor blade for an industrial gas turbine engine with a platform cooling circuit that flows from the suction side of the platform and around both the leading edge and trailing edge of the platform, and then along the pressure side platform to cover the entire platform surface. The cooling air flows along smaller diameter cooling holes that cover substantially the entire pressure side platform surface and is then discharged out through openings onto the pressure side mate-face.
