AGRICULTURAL UNMANNED AERIAL VEHICLE - AMPHIBIA Russian patent published in 2025 - IPC B64U10/70 B64C35/00 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering. Agricultural unmanned aerial vehicle – amphibia includes a body consisting of a fuselage nose part, a fuselage middle part and a fuselage tail part. On the sides of the middle part of the fuselage there are two rectangular slots with a symmetrical arrangement relative to each other, wherein each rectangular slot contains a waterproof steering mechanism, to which a hollow rod is fixed, and at its free end there is an air duct made in the form of a ring, in which a waterproof engine with a six-blade propeller is installed. On the free end of the hollow rod in its cavity there is a bushing with an internal toothed surface protruding beyond the edge of the hollow rod with the possibility of fixing the air duct on it. Bushing is installed in bearing assemblies fixed to the inner upper surface of the hollow rod. Gear wheel is engaged with inner toothed surface mounted on shaft of servomotor fixed to inner lower surface of hollow rod. On the bushing on the side of the air duct attachment there is a gland installed in an annular groove made at the end part of the free end of the hollow rod, where the gland is fixed by a cover bolted to the end part of the hollow rod.

EFFECT: higher manoeuvrability and reduced power consumption during flight.
