Title: Harold E Lemont: Innovator in Propulsive Thrust Technology
Introduction
Harold E Lemont is a notable inventor based in Seymour, Connecticut, recognized for his contributions to propeller technology. With a total of four patents to his name, Lemont has made significant advancements in the field of aerodynamics and propulsion systems.
Latest Patents
One of Lemont's latest patents is the Propulsive Thrust Ring System. This innovative design features a low-aspect ratio propeller system equipped with a multiple ring structure. The structure consists of various circular or non-circular, annular, narrow equivalent air foil rings, which are strategically held by rails in relation to the propeller blades. The upstream ring is positioned downstream from the tip vortex of the propeller, enhancing the overall efficiency of the system. By utilizing one or more additional downstream-located rings, the design creates at least one annular multiple ring-defined pump aperture. This allows peripheral vortices generated by the propeller or fan blades to improve mass flow. The system employs a low-aspect-ratio propeller with high blade angles of attack, ensuring non-stall capability and generating strong vortices that enhance the beneficial effects of the multiple ring structure. These vortices contribute to increased thrust by improving ring flow circulation, while also reducing noise through the destruction of tip and root vortices. Additionally, the multiple ring structure serves as a protective guard against the rotating propeller, ensuring safety for people and animals.
