Title: Innovations by Lisa Shirley Rathbun

Introduction

Lisa Shirley Rathbun is an accomplished inventor based in Scotia, NY (US). He has made significant contributions to the field of turbine technology, particularly with his innovative designs that enhance efficiency and performance.

Latest Patents

Rathbun holds a patent for a "Rotor bore and turbine rotor wheel/spacer heat exchange flow circuit." This invention involves a turbine that features closed-circuit steam-cooling passages around the rotor's rim during steady-state operation. The design allows compressor discharge air to be supplied to the rotor bore, facilitating radial flow into the wheel space cavities between the wheels and spacers. The invention includes communicating slots and channels in the spacers and wheels, enabling the egress of compressor discharge air into the hot gas flow path. During turbine startup, cooling air flows through the closed-circuit steam passages to cool the rotor's outer rim, while compressor discharge air pre-warms the wheels and spacers. At steady-state, cooling steam is supplied in the closed-circuit steam-cooling passages, and compressor discharge air is directed through the bore into the wheel space cavities to cool the rotor.
