VERTICAL TAKEOFF AND LANDING AIRCRAFT Russian patent published in 2020 - IPC B64C29/00 

FIELD: aircraft engineering.

SUBSTANCE: vertical takeoff and landing aircraft comprises fuselage (1) having nose part, tail part and middle part located between them, wings (2) located in tail part of fuselage on sides, made in such a way that lifting force is created at movement of fluid medium in direction along fuselage, keel (4) located in tail part of fuselage (1), horizontal tail unit (3) located in fuselage nose on sides, recesses (7) located in fuselage middle part (1) on sides, turbojet (8) with drive shaft (9) located in tail part of fuselage, fans (14) installed in mid part of fuselage (1) so that they can create fluid flow from hole in upper part of fuselage to recesses (7), in direction from fuselage to sides. Drive shaft (9) is kinematically connected with fans axes through disconnecting clutch (10). There is a reducer, lifting wings (18) pivotally mounted on brackets (15) in recesses (7) and motors (17), made with possibility to rotate wings (18) relative to hinge axis so that in one of extreme positions wings (18) are recessed inside niches (7), and in other of extreme positions are oriented along fluid medium flow from outlets of fans (14). Lifting wings (18) are made so that in takeoff and landing position lifting force is created by fluid flow in direction from fuselage to sides.

EFFECT: aircraft of vertical take-off and landing is described.
