UNMANNED AERIAL VEHICLE OF VERTICAL TAKE-OFF AND LANDING Russian patent published in 2020 - IPC B64C27/22 B64C27/08 B64C39/02 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to unmanned aerial vehicles designs. Vertical take-off and landing vertical unmanned aerial vehicle is arranged in tandem aerodynamic scheme and comprises fuselage with fixed forward and rear wings of reverse boom arranged on fuselage with rear wing shifting up and up in height relative to front wing, with pitch of rear wing installation over pitch is more than front wing. Wing consoles are equipped with aerodynamic control devices configured to hang down at angle of 90 degrees, end cones, bent down perpendicular to plane of wing. On wings cantilevers there are four lifting propeller groups arranged symmetrically relative to centre of masses of said apparatus and containing electric motors and external single-blade profiled screws fixed on electric motors in horizontal hinges with possibility of self-orientation of blades along incident flow. Apparatus also comprises propulsive propulsion group made pusher, with its arrangement at end of rear part of fuselage.

EFFECT: provides for weight reduction, increased reliability.
