Title: Scott J Marshall: Innovator in Turbine Technology
Introduction
Scott J Marshall is a notable inventor based in Phoenix, AZ, who has made significant contributions to the field of turbine technology. With a total of two patents to his name, Marshall's work focuses on enhancing the efficiency and reliability of gas turbine engines.
Latest Patents
Marshall's latest patents include the "First Stage Dual-Alloy Turbine Wheel" and the "Preloaded Duplex Ball Bearing Design." The first patent describes a first-stage turbine designed to receive high-energy air directly from a combustion chamber in a gas turbine engine auxiliary power unit. This innovative turbine features a disk made from a first alloy and a unitary blade wheel formed from a second, different alloy. The blade wheel includes an annular member that is integrally formed with the disk, enhancing the turbine's performance.
The second patent, the "Preloaded Duplex Ball Bearing Design," introduces a bearing assembly that incorporates a centrifugal debris trap. This trap effectively removes contamination debris from lubrication fluid before it reaches the bearing assembly components. By forcing debris into an annular groove on the inner race, the design prevents damage to the bearing balls and races, thereby reducing bearing fatigue and extending the assembly's lifespan.
