Title: The Innovations of Frederick C. Herzner
Introduction
Frederick C. Herzner is a notable inventor based in Fairfield, OH (US). He has made significant contributions to the field of engineering, particularly in the design and functionality of components used in gas turbine engines. With a total of 4 patents to his name, Herzner's work has had a lasting impact on the industry.
Latest Patents
One of Herzner's latest patents is the "Stress-relieved rotor blade attachment slot." This invention aims to eliminate stress peaking at the bearing surface interface of the blade and disk slot dovetails in a gas turbine engine. The design features an undercut slot dovetail that removes disk material from contact with the blade dovetail's radially inner edges, where surface stress peaking would otherwise occur. The undercut contour is determined by analysis based on each engine design, ensuring a substantially uniform distribution of surface stress along the dovetail slot fillet radius.
Another significant patent is the "Coolant pressure regulating apparatus." This apparatus includes a predetermined number of coolant pressure regulating valves that rotate against a spring bias to divert coolant flow and excess pressure from the coolant air fan duct into the engine core exhaust flow. The pressure regulator valve effectively regulates the pressure within a closed cavity suppressor to match the pressure level within the core, without affecting the upstream fan duct pressure.
