Title: Innovations by Michael A. Quadrini
Introduction
Michael A. Quadrini is an accomplished inventor based in Westerly, Rhode Island. He has made significant contributions to the field of marine propulsion technology. With a total of 2 patents, his work focuses on innovative designs that enhance efficiency and performance in marine applications.
Latest Patents
One of his latest patents is the "Rim-driven propulsion pod arrangement." This invention features a cylindrical housing with a duct that provides a flow path for water. It includes a rotor assembly supported by a central shaft, which contains a rotating blade row driven by a rim drive permanent magnet motor. The design incorporates an array of vanes downstream from the blade row to straighten the water flow. Additionally, radial bearing members on the rotor are designed with a hardness less than that of the supporting shaft, and soft protrusions limit rotor excursion. A thrust bearing is also included to form a water wedge during rotor rotation.
Another notable patent is the "Strut-mounted marine propulsion unit." This unit is supported by a strut from a vessel and contains an electric motor within a housing. It features a forward propeller with a larger diameter than the housing, along with hydrodynamic vanes that counteract tangential flow. The aft section includes counter-rotating blade rows driven by the electric motor, surrounded by a shroud that inhibits cavitation and improves efficiency. The shroud's rearward portions are movable, creating a clamshell effect that reverses liquid flow.
