SHORT TAKEOFF AND LANDING FLIGHT ON THE BASIS OF AN-148 AIRCRAFT

摘要

The utility model relates to aircraft that differ in the placement of power plants, in particular, with jet engines attached with the possibility of rotation to the wings, and can be used, for example, in civil aviation. The objective is to provide a shorter runway for take-off and landing. The short take-off and landing aircraft based on the AN-148 airplane (hereinafter referred to as the airplane) (Figs. 1, 2) contains the fuselage 1, a highly located articulated wing 2, two turbojet engines 3 'and 3' 'mounted on the wings 2 near the fuselage 1 , side doors 4, performing in the open state the function of a ladder, chassis 5, control system and navigation equipment (6). Moreover, each of the turbojet engines 3 is attached to the wing 2 by means of three movable supports, connected to the control system 6, in front of two hinge supports 7 ', 7' ', behind the third support 8, made in the form of a telescopic hydraulic cylinder connecting the lower part of the body engine 3 with the lower plane of the wing 2 near the fuselage 1, providing the ability to rotate the engines 0-90 ° relative to the plane of the wing, where 0 is horizontal, 90 ° is vertical. At the ends of the wings, floats 9 can be removably mounted to allow for landing on water. Turbojet engines are attached to the wings by means of three movable supports - two hinged supports in front, connecting the middle part of the engine bodies with wings, and a third telescopic support in the back, connecting the lower part of the bodies engines with the lower surface of the wings, in conjunction with the connection of all the supports with the aircraft control system, the ability to rotate turbojet engines relative 0–90 °, which makes it possible to reduce the length of the strip for takeoff and landing. 1 s.p. f-ly, 2 ill.
