  2. Voith Schneider Propeller - Wikipedia

    en.wikipedia.org/wiki/Voith_Schneider_Propeller

    The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...

  3. Rim-driven thruster - Wikipedia

    en.wikipedia.org/wiki/Rim-driven_thruster

    Rim–driven thruster, presented at SMM 2010 A rim-driven thruster mounted on a swing-out unit (design by silentdynamics GmbH) Voith rim thruster at SMM 2010 in Hamburg. The rim-driven thruster, also known as rim-driven propulsor/propeller (or RDP) is a novel type of electric propulsion unit for ships.

  4. Marine propulsion - Wikipedia

    en.wikipedia.org/wiki/Marine_propulsion

    Voith Schneider Propeller. A Voith Schneider Propeller (VSP) is a practical cyclorotor that provides instant thrust in any direction. There is no need to turn a propulsor. Most ships with VSPs do not need or have a rudder.

  5. Marine thruster - Wikipedia

    en.wikipedia.org/wiki/Marine_thruster

    [clarification needed] The choice between using thrusters or traditional propellers to propel marine vessels is a compromise between versatility and efficiency. Propellers are designed to work in-line with a propulsion plant and produce one-directional thrust while thrusters are more customizable and have a more versatile application.

  6. Protector (fireboat) - Wikipedia

    en.wikipedia.org/wiki/Protector_(fireboat)

    Protector is propelled by a pair of Voith-Schneider propellers, an advanced propulsion system that bears some resemblance to helicopter propulsion, and enable instantaneous changes in the propeller thrust. [1] She is 108 feet long, with a maximum speed of 13 knots.

    2 × 3,800 kW (5,096 hp) Voith Schneider Propellers VSP 36R6EC/300-2 ; 1 × 1,350 kW (1,810 hp) Rolls-Royce TT2400 DPN CP azimuth thruster (retractable)

  8. Advance ratio - Wikipedia

    en.wikipedia.org/wiki/Advance_ratio

    It helps in understanding the efficiency of the propeller at different speeds and is particularly useful in the design and analysis of propeller-driven vehicles.It is the ratio of the freestream fluid speed to the propeller, rotor, or cyclorotor tip speed. When a propeller-driven vehicle is moving at high speed relative to the fluid, or the ...
