SKROGKONSTRUKSJON FOR OVERFLATEFARTOEY MED SLINGREKJOELER OG FARTOEY BASERT PAA SLIK KONSTRUKSJON.

摘要

The present invention relates to hull forms for a surface-effect ship including a buoyancy structure of the catamaran type equipped with two lateral keels 100, joined by a central structure, adapted to sail either in Archimedean sailing on its hull, or lifted on a cushion of air, the lateral keels 100 delimiting, with two closing devices, the central lifting air cushion C. The forms are characterised in that each of the two keels 100 includes a floor plate section 110, an inner side wall 120, turned towards the cushion C, and an outer side wall 130, the floor plate segment being inclined outwards with respect to the horizontal and rising from the rear forwards on the keel up to a deep V at the extreme front, the inner wall 120 being substantially vertical at the front and at the rear and having a swelling in its upper central part 170, the outer wall 130 changing from the rear forwards from a concave curve to a convex curve, so that the optimal performance is achieved for the two modes of buoyancy and Archimedean sailing.
