TRIPLE-SCREW CONVERTIPLANE Russian patent published in 2018 - IPC B64C37/00 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering. Proposed triple-screw convertiplane consists of a fuselage with a wing attached to it according to the plan of the high-wing, two-keel tail unit located on the leading edge of the engine wing with screws and a swivel mechanism allowing to change the thrust vector at 110° with respect to the horizon for changing flight regimes. There is an additional power unit with a horizontal screw arrangement, located in the tail part of the horizontal keystone and serving to stabilize the aircraft in pitch in helicopter flight mode, control the direction of movement of the convertiplane, and also equipped with a pivoting mechanism allowing the deflection of the thrust vector in the vertical plane to compensate for the torque generated by the front propulsion systems, and control the yaw of the aircraft in helicopter and transient flight modes.

EFFECT: invention is aimed at simplifying the flight control system, increasing the reliability and safety of the flight during the transition from helicopter mode to aircraft.
