HYDROCONVERTI GROUND-EFFECT CRAFT Russian patent published in 2005 - IPC

FIELD: aeronautical engineering; building hydroconverti ground-effect craft.

SUBSTANCE: proposed hydroconverti ground-effect craft has low-wing monoplane, mid-wing monoplane and high-wing monoplane arranged in tandem. Mounted on their outer panels are annular channels equipped with turning units and cantilever propellers for creating vertical and horizontal thrust; they are provided with propeller gearboxes mounted on stiffening ribs; front and rear ones are combined by means of transversal and longitudinal transmission shafts located at different levels with two intermediate T-shaped gearboxes driven by power plant. Power plant is provided with at least two main engines mounted in gondolas on either side from longitudinal axis of fuselage-gondola on upper part of high-set wing. Vertical tail is mounted on tail boom. Three-leg landing gear is retracted into fore compartment. The proposed hydroconverti ground-effect craft is built in three-boom pattern. High-set wing is additionally provided with two booms at level of tail boom. Mid-set wing is made in form of stabilizer and its two propellers are just inter-boom propellers; they are provided with units for turning the annular channels which are mounted coaxially relative to single transversal axis of horizontal stiffening ribs located in stabilizer plane. Hermetic side compartments smoothly change to aft compartment behind aft section of fuselage-gondola. Aft compartment is provided with two C-shaped cuts under inter-boom propellers without shading them in creating the vertical thrust. Aft compartment is made under tail boom along its longitudinal axis in form of streamlined aft float of longitudinal stability.

EFFECT: improved service characteristics.
