METHOD FOR LANDING UNMANNED HELICOPTER ON MOVING VESSEL Russian patent published in 2021 - IPC B64F1/18 B64D45/04 G05D1/10 B64C13/18 

FIELD: unmanned helicopters.
SUBSTANCE: invention relates to a method of landing an unmanned helicopter on a moving vessel. For landing an unmanned helicopter, using the ship landing equipment, a landing zone is formed, which is a reference point for the helicopter camera. A descent maneuver is performed in a certain way, taking into account the pitching, yawing and movement of the ship. The helicopter is landed. Using the ship computing device, a landing zone is formed at a fixed height in the form of a virtual landing plane in the form of a quadrangle, as well as with the possibility of moving it in a horizontal plane with the speed of the ship on its course. The helicopter is moved along the trajectory of descent, holding the image of the virtual landing plane in the limiting field of the camera field of view until the limiting field of the helicopter camera field of view is combined with the image of the virtual landing plane. The helicopter is held at the final point of descent until the helicopter deck occupies the position with the highest elevation in space when the ship diametrical plane passes through the longitudinal central axis of the virtual landing plane, at which point the helicopter is given the command to land.

EFFECT: improved landing accuracy and safety are provided.
