HIGH-SPEED HYBRID DRONE COPTER-PLANE Russian patent published in 2012 - IPC B64C27/22 B64C37/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to drones. Proposed hybrid plane represents a monoplane with all-moving front horizontal empennage, twin-fin tail secured to outer wings secured to nacelles, all-moving tailplane and fin extensions above and below nacelles. All-moving tailplane can deflect spaced apart outer wings. Lift surfaces are located in lengthwise plane without shadowing each other to composed triplane lengthwise arrangement. Torque of two tandem gas turbine engines is transmitted via transmission to tractor and pusher propellers to produce horizontal and vertical thrust. Airplane transmission consists of main reduction gearbox, nose and tail reduction gears, lengthwise shafts arranged on both sides of the plane of symmetry and parallel therewith and equipped with fixed-angle reduction gears. Nose and tail cones are provided with top and bottom lengthwise opening apertures furnished with guides for displacement of casing of rotary shaft with propeller of appropriate reduction gear.

EFFECT: better stability and controllability.
