FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to VTOL aircraft lift increasing systems. Proposed device comprises rotary power plant with propellers, turn drive, load damping automatic devices, retention locks, fuel system with pipeline turning branch and control system for engine with propeller extending through turn assembly. Note here that engine nacelle turn drive is arranged at the pylon end cross-section, pylon being fitted ay wind tail section, ahead of the flap articulated with suspension bracket and via drawbar lower link fastening assembly and flapping link is articulated with engine nacelle. Flap drive screw mechanism is articulated with flap assembly arranged at its top leading part. Lower drawbar link at the flap as-retracted position makes the part of pylon tail compartment.
EFFECT: higher efficiency of lift increase device, simple device, decreased weight.
