AIR-CUSHION SELF-PROPELLED PLATFORM FOR OPERATION IN ARCTIC REGIONS Russian patent published in 2007 - IPC B60V3/06 

FIELD: shipbuilding.

SUBSTANCE: invention relates to air-cushion platforms for operation in polar regions. Proposed air-cushion platform has carrying body with air cushion guard arranged around and provided with receiver installed on side crinolines attached to body, pressure complex with engine, drive and centrifugal blowers of air cushion, control house with control station of pressure complex. Carrying body of air-cushion self-propelled platform is made in form of pontoon. Its upper surface is cargo deck with possibility of through passing. Platform is furnished additionally with pressure complex, propulsion complex with main engines with drives and aircraft air variable-pitch propellers in nozzles, and auxiliary gas-turbine engines for starting main engines, and system to control main engines of propulsion and pressure complexes of air cushion, fuel system, fire system and platform control system whose control stations are arranged in control house. Propulsion complexes are located in cargo deck in stern part of platform on either side. Pressure complexes are arranged on cargo deck in middle part of platform along its length on either side, being system of centrifugal air blowers located on one axle with the same drive as propulsion complexes. Steering complex of platform consists of aerodynamic rudders arranged vertically behind screw propellers and thrusters installed on either side in bow part of platform communicating with receiver of flexible guard. Aircraft gas-turbine engines type TB3 are used in drives of propulsion and pressure complexes, engines whose service life has expired can be used for this purpose.

EFFECT: provision of ecologically safe air-cushion self-propelled platform of simplified design at reduced cost of its manufacture and operation.
