METHOD OF CONTROLLING PITCH OF CONVERTIPLANE Russian patent published in 2024 - IPC B64C37/00 

FIELD: aviation.

SUBSTANCE: in tail part of convertiplane, directly behind rotary fan, there is a rudder plate, and there are also hatch and shutters interacting with fan. During takeoff/landing, as well as during transition from vertical flight to horizontal flight and vice versa, fan is installed in horizontal position, wherein the curtains are closed and the hatch is opened, thereby providing a downward air flow when thrown by the fan to create an aerodynamic force acting on the arm from the center of mass of the aircraft to the axis of rotation of the fan and creating a moment from the aerodynamic force on this arm. During horizontal flight, the curtains are opened, the hatch is closed, air is forced onto the rudder plate by means of a fan, at the same time creating moment from aerodynamic force with arm from center of mass to center of pressure of plate-rudder arising at flow around plate-rudder.

EFFECT: higher maneuverability, longitudinal stability and safety of convertiplane during takeoff and landing, during transition from vertical flight to horizontal flight and vice versa, as well as throughout the flight.
