Title: Calvin A. Gongwer: Innovator in Jet Propulsion and Outboard Motor Technologies
Introduction
Calvin A. Gongwer, based in Glendora, CA, is a prolific inventor with an impressive portfolio comprising 36 patents. His innovations primarily focus on advanced propulsion systems, showcasing his expertise in the field.
Latest Patents
Among his latest contributions, Gongwer has patented a jet propulsion device that features a unique method for controlling movement. This device incorporates liquid inlets strategically positioned at a distance from its surface, specifically within the stabilizing fins. When the device attains a certain velocity, a Riabouchinsky cavity is formed around it, with the cavity's radius closely matching the distance between the inlets and the device's longitudinal axis. Additionally, he developed a safe and efficient outboard motor assembly designed for external propulsion of watercraft. This assembly consists of a drive assembly, shaft assembly, and an impeller-jet assembly. The impeller-jet assembly enhances water flow through the inclusion of an inlet stator, exit stator, impeller, and surrounding housing. The tapered exit stator design creates a circular array of nozzles, improving water flow efficiency by removing any twisting motion.
