Auxiliary flotation, propulsion and steering unit for tracked and/or wheeled land vehicles

摘要

An auxiliary flotation, propulsion and steering unit for tracked and/or wheeled land vehicles, particularly cargo carriers (10) of the "Cargo Carrier M548" type. The unit comprises at least one bow flotation section (21) and one stern flotation section (22), both whereof are constituted by watertight containers filled with foamed material (MP) which are detachably connected to the hull of the vehicle. The bow section (21) is profiled so as to generate lift for hydrodynamic support and includes two propulsion and steering propellers (24) of the ducted type, which are orientated with their axes inclined downwardly, so that the jets of water generated by them have vertical thrust components which are directed upwardly whereby to provide auxiliary supporting actions for the bow section (21). <IMAGE>
