FIELD: aircraft engineering.
SUBSTANCE: invention relates to aircraft engineering, particularly, to vertical take-off and landing aircraft. Vertical take-off and landing aircraft (VTLA) comprises two turbojet engines, devices for gas removal from the turbojet engine, a body-wing, in which there is a hollow ring lying in the plane of the body-wing, an ejector of arcuate shape placed above it, smoothly entering from above into the hollow ring. Nozzles of the ejector are connected to the devices for gas removal from the turbojet engine. On the outer side of the hollow ring, gas removal sleeves are tangentially attached and selecting the rotating gas-air flow from the hollow ring, dividing it into rectangular jets and guiding them under the body-wing into a cylindrical recess in the lower part of the body-wing (into the cavity of the flat diffuser), formed when the lower cover is pulled into the body-wing. Said jets run parallel to the surface of the lower cover, radially to the vertical axis of the cylindrical recess and evenly from all sides.
EFFECT: low-speed vertical gas-air jet is provided in vertical take-off, landing and hovering modes.
