GROUND-EFFECT CRAFT Russian patent published in 2007 - IPC B60V1/08 

FIELD: hovercraft; manufacture of hovercraft.

SUBSTANCE: proposed ground-effect craft has fuselage, hydrofoil, horizontal and vertical tails, cruising (air propeller) and booster propulsors with respective engines and landing gear. Engine, turbo-jet engine for example, is located in nose section of fuselage in passage provided with air intake with doors, as well as with nozzle and flap which is provided with doors which form slit at deflection. Trailing edge of lowered flap is located in front of leading edge of hydrofoil. In raised position, flap forms extension. Propeller is mounted in front of horizontal tail and is connected with airframe for rotation about axis passing through axis of rotation of propeller and center of mass of engine and engine nacelle which are connected with propeller.

EFFECT: reduction of aerodynamic drag at cruising speed; enhanced controllability of ground-effect craft during motion at supercharging.
