Abstract
An amphibian vehicle having a vehicle body, and at least a pair of floaters attached to the vehicle body, each of which floaters consists of a cylindrical body having a buoyancy, and a helical blade fixed to the outer circumferential surface of the cylindrical body. This amphibian vehicle is formed such that the water line of the amphibian vehicle at a front end surface of each of the floaters is not higher than the center line thereof, with the water line of said amphibian vehicle at a rear end surface of each of the floaters not higher than a level which is higher than the center line of each of the floaters by 30% of the diameter thereof.
Claims6
An amphibian vehicle for use in ice-forming water areas having a vehicle body, and at least a pair of floaters attached to said vehicle body, each of which floaters consists of a bouyant cylindrical body having a tapered forward end, and a helical blade fixed to the outer circumferential surface of said cylindrical body including said tapered end, characterized in that the waterline of said amphibian vehicle at the front of each of said floaters is not higher than the centerline thereof, with the waterline of said amphibian vehicle at the rear of each of said floaters not higher than 30% of the floater diameter above the centerline of each of said floaters.
