TRANSPORT VEHICLES WITH TRANSPORT BODY, TAXED TRANSPORT BODY AND AIRCRAFT BODY

摘要

The ferry boat has a rectangular main deck with superstructure above and hull structure below. The superstructure is essentially rectangular in all views and has one or more decks with a plurality of traffic lanes on each deck in addition to those on the main decks with optional passenger carrying compartments. The lanes are straight and parallel and there are no deck-to deck ramps. The hull structure has two sidewalls, one along each of the long sides of the main deck and two skirts, one at each end of the main deck. The skirts extend between the sidewalls and have vertical aft surfaces and front surfaces which slope downward and aft. The lower extremities of the sidewalls are further from the main deck than the apexes of the skirts. The volume enclosed by the sidewalls, skirts, main deck and water surface is filled with entrapped air which will compress to provide a major part of the support of the boat. There are two hydrofoils, one forward, one aft and extending between the sidewalls. Each foil is supported from the deck structure by several struts. The struts and foils have blunt trailing edges ventilated by air ducted down the struts. The foils are submerged about one chord length below the lower edges of the sidewall and the lower edges extend below the apexes of the dams.
