Title: Innovations of Stephen Arthur Anderson
Introduction
Stephen Arthur Anderson is a notable inventor based in Verdun, CA. He holds a total of 5 patents that showcase his contributions to the field of engineering, particularly in gas compression technology.
Latest Patents
One of his latest innovations is the Hybrid Compressor, which features at least one rotor and shroud that define a compressor gas path extending from an inlet to an outlet. This 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 positioned between the compression stages. The design allows for controlled blade aerodynamic loadings, particularly in the last stage, to achieve desired compression characteristics across the compressor. Additionally, a bleed outlet is optionally located between the inlet and outlet for bleeding from the gas path.
Another significant patent is the Gas Turbine Braking Apparatus and Method. This device serves multiple functions, including impeding the rotation of a shaft decoupled turbine rotor and selectively impeding the rotation of a first spool of the engine. This functionality allows for a second spool to generate power for use in ground operations, facilitating reduced aircraft ground speed.
