Auxiliary flotation, propulsion and steering gear for multipurpose vehicles with amphibian functions

摘要

The gear comprises at least two auxiliary flotation sections, respectively a forward section and a stern section, which can be detachably associated with the hull of the vehicle, each section being constituted by a profiled metal container. The forward section has immersed surfaces which are profiled so as to produce lift for hydrodynamic support, and the stern section includes two thrust propellers of the ducted type, arranged symmetrically with respect to the longitudinal centerline plane of the vehicle; auxiliary motor means being provided in order to simultaneously or selectively turn said propellers both for propulsion and for steering.
