FIELD: transportation.
SUBSTANCE: invention relates to transport facilities on compressed airflow of high cross-country capacity. Amphibious vessel on compressed air flow with submersible screw propulsor comprises bottom made of parts at different angles, and rudder comprises shields. In the aft part of the body above the steering device there is a horizontal flow-guiding element in the form of U-shaped apron. Air pressure is created due to coaxial impeller and differentiated outlet from additional channel at output between steering devices. Bottom of the pneumatic channel in the cross section is flat. In addition, left and right screw propellers, which are controlled by speed and direction of rotation of screws, are fixed on sides of ship sides. Blade heights in each of screw crosswise sections are limited by value equal to 0.75 of hub diameter, outer edges of blades are sharpened, and before entering into section of streamlined head screws are protruded forward and closed from above with curvilinear apron. Screws are arranged with possibility of exit and contact with water medium or land with possibility of lifting and lowering screws by means of lifting mechanism in form of hydraulic drive of volumetric action and communication via hydraulic drive with small internal combustion engine, which is used to actuate all means of implementing traction force of screws in water or on land.
EFFECT: broader functional capabilities, higher efficiency and higher speed of vessel on compressed airflow.
