Rim-driven thruster technology has emerged in recent years, demonstrating its potential for compact and silent maneuvering propulsion.
Early development for this technology performed in Rostock, Germany at the company AIR. The project was then taken over by Voith, and the development of the Voith Inline Thruster and Voith Inline Propulsor was then continued.
After the Voith factory was shut, the development team decided to offer its experience in rim-driven thrusters on its own through the newly established brand, Silentdynamics.
According to the developers at Silentdynamics, possible applications include, but are not limited to, tunnel thrusters. The brand’s ERT thrusters can also be configured to be retractable and/or azimuthing. Additionally, individual solutions for reduction of weight and dimensions are possible.
The rim-driven thruster concept offers the low noise emissions and compact dimensions achieved by utilizing carbon-fiber blades, water-lubricated hydrodynamic bearings and a hubless propeller design without any obstacles in the flow path.
