Detailed description
Hull and superstructure. Material of hull and superstructure – aluminium-magnesium alloy. The connection elements of the hull and superstructure are rivets and argon-arc welding. Riveting of impermeable seams is made with sealants.
Air-cushion consists of longitudinal inflatable side and central balloons, transverse bow, stern and central skirts. The bottom surfaces of the air cushion are protected against wear and damages with polyurethane coating. The pressure regulation system in the lower balloons allows you to change the pressure in motion and during parking. Engine systems. Four diesel engines drive air cushion charging and propulsion systems.
Two engines drive propulsion system and two engines drive charging system via via clutch, toothed belts and drive shafts.
Engines. Six diesel engines are installed on the ship to drive the lifting and propulsion systems.
Two engines drive the lifting system and four engines drive the propulsion system via clutch, toothed belts and cardan shafts.
Propulsion system consists of four counter-rotating adjustable pitch propellers in rings. Hydraulic control system enables to change the angle of the blades and provides the reverse thrust by means of the main propellers.
The hovercraft is steered via air rudders installed behind the main propellers. Air rudders are driven by means of the hydraulic system.
Lifting system consists of 6 centrifugal superchargers. Each supercharger charges air into corresponding part of the air cushion.
Interior layout and equipment. A 19.5 x 7.5 m cargo deck a bow ramp for loading wheeled and tracked vehicles are provided for cargo placement.
Propulsion and steering system is located in the aft part of the vessel, the lifting system with air cushion superchargers is located in compartments on the left and starboard sides.
Wheelhouse is located in the bow on the port side.
Passengers are stationed in the bow compartments on the port and starboard sides.
