AIRCRAFT VERTICAL TAKE-OFF SYSTEM Russian patent published in 2016 - IPC B64D3/00 B64C29/02 

FIELD: aviation.

SUBSTANCE: aircraft vertical take-off system (AKVV) consists of unmanned heavy carrier aircraft (BTSN) and two towed on wing tips light multipurpose aircraft (BLMS), each of which has fuselage with front arrangement of engine and two coaxial pull screws mounted in non-retractable landing gear with wheels mounted at cowls on ends of keels of tail fin. AKVV is made based on concept of distributed thrust of different-size rotors (RTRV) at X2+4 scheme, ensuring possibility of transformation with joining flight configuration for proposed and horizontal cruising flight in separate three twin-screw flight configurations for horizontal flight, coupling/uncoupling in air. BTSN and BMLS are made on based on concept of “tailless aircraft” and biplane scheme and is equipped with two top and two bottom keels. Each nacelle has screw with front arrangement inside arched cantilever of first wing. To perform coupling/uncoupling via “wing - in pylon fairing” each BLMS is equipped with corresponding decomposable catcher, having a system of emergency detachment by explosive bolts.

EFFECT: simplified longitudinal controllability at hovering, improved transverse controllability at towed flight.
