Title: Innovations by James E. Sidenstick
Introduction
James E. Sidenstick is a notable inventor based in Cincinnati, OH (US). He has made significant contributions to the field of turbine technology, holding a total of 3 patents. His work primarily focuses on enhancing the efficiency and performance of hot gas turbine engines.
Latest Patents
One of his latest patents is titled "Shroud means for turbine rotor blade tip clearance control." This invention involves a hot gas turbine wheel shroud ring that is designed to be concentrically positioned around the periphery of a row of turbine blades. It aims to provide a predetermined small sealing and running clearance between the tips of the turbine blades and the shroud ring. The shroud ring is characterized by unique warping or deflection properties that differ from those typically found in shroud rings under high-temperature operating conditions.
Another significant patent is related to "Clearance control." This system is integrated into a turbomachine to manage the operational clearance between a turbine rotor and its surrounding shroud. It consists of multiple control rings within the turbine casing that expand and contract thermally to adjust the radial positioning of the turbine shroud. By directing compressor air through internal passages in the rings, the system effectively utilizes the pressure and temperature of the compressor air to match the thermal growth of the control rings and turbine shroud with that of the turbine rotors, thereby controlling clearance.
