Silent Service

  • Rim-driven thruster technology has emerged and demonstrated potential for compact and super-silent maneuvering propulsion.

     

    Silentdynamics customized rim-thruster-based propulsion solutions applications include tunnel thrusters, and Silentdynamics ERT thrusters can be configured to be retractable and/or azimuthing. Major benefits include low noise emissions and compact dimensions. This is achieved by utilizing carbon-fiber blades, water-lubricated hydrodynamic bearings and a hubless propeller design. www.silentdynamics.de
