VERTICAL TAKE-OFF AND LANDING AIRCRAFT Russian patent published in 2019 - IPC B64C27/30 B64C37/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly to vertical take-off and landing aircrafts. Vertical take-off and landing aircraft comprises fuselage, keel, two front and rear wings, two lifting power units arranged on fuselage with two axes of rotation on both sides and pylons capable of fixing the position, sustainer power plant. Axes of rotation of pylons of lifting power units by angle of yaw are inclined relative to the connected coordinate system and are made with possibility of lifting power units laying in the fuselage niche. Axes of rotation of lifting power units by pitch angle are inclined relative to pylons with possibility of providing rotation of lifting power units in takeoff-landing flight mode by pitch angle. Lifting power unit is made with possibility of folding into fuselage niche by joint rotation relative to both axes of pylon turn, at that, lifting power units are turned with screws downward.

EFFECT: higher reliability, stability and controllability of aircraft in takeoff-landing mode of flight.
