HYBRID QUADCOPTER Russian patent published in 2019 - IPC B64C27/08 B64B1/34 

FIELD: aviation.

SUBSTANCE: invention relates to rotorcraft. Hybrid quadcopter comprises a gas-filled shell in the form of a biconvex lens with a soft horizontal-folded surface, resting on an inner central axial telescopic column with embedded links, a nacelle with onboard control equipment, which is lowered to the shell, accumulator battery, crosswise-extended brackets and reversible air-screw aircraft engines of variable thrust at their ends. Axial embedded link of telescopic column is extended upwards from coaxial embedded link and housing of column, part of which extends beyond shell, having plug and fasteners on end. Shell support on the telescopic column is carried out due to connection of the rigid convex cover of the shell to the upper end face of the enclosed axial link, and also through connection of the hard flat bottom of the shell to the column body. Bottom has two automatic valves for supply and bleeding of light gas from the shell.

EFFECT: invention is aimed at improvement of streamlining of horizontally-folded surface.
