Vertical taking-off and landing rack structure of fixed-wing aircraft, and vertical taking-off and landing fixed-wing aircraft

The invention belongs to the technical field of aviation, and particularly relates to a vertical taking-off and landing rack structure of a fixed-wing aircraft and the vertical taking-off and landing fixed-wing aircraft. The vertical taking-off and landing rack structure comprises a fuselage and wings, the fuselage is of a hollow structure formed by a shell supported by transverse keels and longitudinal keels, the fuselage is provided with a front opening, a rear opening, a left opening and a right opening, engines are respectively arranged on the front opening and the rear opening, and the two wings are respectively fixed at the positions of the left opening and the right opening; and the airflow is ejected from the left and right openings, acts on the two wings, and forms an upward lift. The vertical taking-off and landing rack structure of the fixed-wing aircraft and the vertical taking-off and landing fixed-wing aircraft aim to mutually compensate the advantages of a vertical taking-off and landing techno
