Title: Innovations by Gary Weir in Compressor Technology
Introduction
Gary Weir is an accomplished inventor based in Markham, Canada. He has made significant contributions to the field of compressor technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and performance of gas compressors, particularly in applications related to gas turbine engines.
Latest Patents
One of Gary Weir's latest patents is for a hybrid compressor. This innovative design features at least one rotor and shroud that define a compressor gas path extending from an inlet to an outlet. The hybrid compressor includes at least two compression stages and one diffusion stage between the inlet and outlet. The compression stages consist of respective circumferential arrays of blades extending from the rotor, while the diffusion stage includes a circumferential array of vanes. This design allows for controlled blade aerodynamic loadings, particularly in the last stage, to achieve desired compression characteristics. Additionally, a bleed outlet is optionally located between the inlet and outlet for bleeding from the gas path.
Another notable patent by Weir is for a mixed flow and centrifugal compressor designed for gas turbine engines. This two-stage compressor features a mixed flow first stage and a centrifugal second stage, connected by an intermediate duct. The mixed flow stage includes a mixed rotor with a circumferential array of mixed flow blades, while the downstream centrifugal stage has a centrifugal rotor with radially extending centrifugal flow blades. The intermediate duct is designed to direct airflow from the mixed rotor radially inwardly and axially rearwardly toward the centrifugal rotor, optimizing performance.
