Abstract
Abstract A wreck-resistant, lightweight vehicle, adapted to traverse water and optionally to travel also in air or space, comprising: a barrel-curved, preferably rigid-walled cabin; resilient fluiddynamic foils or wings above and spaced from the cabin; fluiddynamic foils below and spaced from the cabin (serving in travel thru water as hydrofoils that lift the cabin clear of the water''s surface); resilient fluidfoil supports, strongly connecting the ends of each pair of the upper and lower fluidfoils, fitted and bonded to the vertical curves of the cabin sidewalls; and, optionally and preferably, vehicle-stabilizing balloon means, comprising a series of balloon bags in a streamlined skin, fitted between and bonded to the top of the cabin and each upper fluidfoil. The invention includes lightweight, strong, cabinwall, endless ribs, comprising curved, thin-walled tubes that are strongly inflated with gaseous material and surrounded by integral, strong insulation which comprises substantially rigid foamed plastic, or very lightweight concrete, or similar material. The ribs are epoxy bonded together in a fore-and-aft series, and sheathed in a waterproofed skin.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
288 words
A vehicle, adapted to transverse water, comprising: a cabin, having: a longitudinal, fore-and-aft axis; top and bottom walls; and sidewalls, having vertically curved outer surfaces which form in intersection with cross-sectional planes normal to said axis vertical, arcuate, outwardly convex curves; strongly resilient fluidfoil means, below and spaced from the bottom of the said cabin, functioning as a hydrofoil when traveling in water, comprising at least one fluidfoil, with spaced ends that are below spaced side portions of the cabin, having: a plurality of fore-and-aft-arranged fluidfoil tubes that are annular in cross section and have different diameters, with at least one tube of a smaller diameter being positioned aft of a tube of larger diameter; gaseous material in the interiors of said tubes; foamed plastic, surrounding the tubes; and a waterproof, fluid-dynamically shaped fluidfoil skin, tautly positioned around said foamed plastic and tubes; and resilient fluidfoil-support means, comprising support structures on the sides of the cabin; each of said structures having an upper end located generally above one of said fluidfoil ends, and comprising: support tubes, each of which has substantially the same diameter as a matching tube of the fluidfoil tubes and is fixed to said matching tube; gaseous material in the interiors of said support tubes; foamed plastic surrounding the support tubes; and a waterproof support skin, shaped to reduce drag from the relative flow of fluid in travel, tautly positioned around said last-named foamed plastic and tubes; and in which each of the said structures has a portion that is closely adjacent to and is curved to fit against one of said vertically curved outer sidewall surfaces, and comprises means securely and strongly fastening said adjacent portion to said one of the vertically curved surfaces.
Claim 2
Dependent Claim
288 words
A vehicle, adapted to transverse water, comprising: a cabin, having: a longitudinal, fore-and-aft axis; top and bottom walls; and sidewalls, having vertically curved outer surfaces which form in intersection with cross-sectional planes normal to said axis vertical, arcuate, outwardly convex curves; strongly resilient fluidfoil means, below and spaced from the bottom of the said cabin, functioning as a hydrofoil when traveling in water, comprising at least one fluidfoil, with spaced ends that are below spaced side portions of the cabin, having: a plurality of fore-and-aft-arranged fluidfoil tubes that are annular in cross section and have different diameters, with at least one tube of a smaller diameter being positioned aft of a tube of larger diameter; gaseous material in the interiors of said tubes; foamed plastic, surrounding the tubes; and a waterproof, fluid-dynamically shaped fluidfoil skin, tautly positioned around said foamed plastic and tubes; and resilient fluidfoil-support means, comprising support structures on the sides of the cabin; each of said structures having an upper end located generally above one of said fluidfoil ends, and comprising: support tubes, each of which has substantially the same diameter as a matching tube of the fluidfoil tubes and is fixed to said matching tube; gaseous material in the interiors of said support tubes; foamed plastic surrounding the support tubes; and a waterproof support skin, shaped to reduce drag from the relative flow of fluid in travel, tautly positioned around said last-named foamed plastic and tubes; and in which each of the said structures has a portion that is closely adjacent to and is curved to fit against one of said vertically curved outer sidewall surfaces, and comprises means securely and strongly fastening said adjacent portion to said one of the vertically curved surfaces.
