METHOD FOR OBTAINING ADDITIONAL COMPRESSED AIR PRESSURE OF AMPHIBIOUS SHIP ON COMPRESSED AIR FLOW

摘要

FIELD: vessels and other watercrafts.;SUBSTANCE: invention relates to the field of the dynamic air cushion using vehicles development. Disclosed is a method of producing additional compressed air for an amphibious ship on a compressed airflow having a body with a propulsion unit, generating air pressure under the bottom and propelling the ship. Bottom is made with side skegs and closed pneumatic channel with rectangular bottom equipped inside by rotary vertical shields with their axes of rotation with reversible geared motors-angular gearboxes. One end of rotary shields is connected with axis of rotation, and other end - through hinge with cantilever vertical shield. Axes of shields are located near side walls of skegs in closed pneumatic channel, and they are connected by straight rods arranged on deck, with ship control system, vertical planes of rotary shields are made with holes of perforation, external surface of which towards the stern is made with curved plates in form of finning, as a result, air fills the formed space between skeg side walls and angle-curved flaps, each pivot flap can be located inside closed pneumatic channel in one vertical plane with walls of closed pneumatic channel, at which they form free passage from closed pneumatic channel to open pneumatic channel with diffuser side walls, made to provide common jet draft of air jet outlet towards coma with steering devices, where, mixing, forming common outflow of water-and-air flow between rotary steering shields.;EFFECT: higher speed of movement, improved controllability.;1 cl, 4 dwg
