    Hi everybody interested in the flapping foil propulsion.
    Please see my small boat experiment:

    Thanks for posting! Congratulations.

    What advantages does this system offer over a propeller driven system? What applications do you see this being used in?

    Thank You!
    Thay say that such system has the following advantages:
    - are relatively low-frequency systems,
    - possess sufficiently high efficiency,
    - are multi-functional in the sense of being capable of
    operating in different regimes of motion,
    - can combine the function of propulsor, control device
    and stabilizer,
    - can provide high maneuverability,
    - possess more acceptable cavitation characteristics
    than conventional propellers,
    - have relatively low aerodynamic drag in the
    switched-off position, etc...

    The closest analogue, as I think, is the Voith Schneider Propeller
    that combines propulsion and steering in one unit.
