(57) Abstract: The invention relates to aeronautical engineering. The aircraft includes a fuselage, a wing, means of mechanization, designed to adapt the wing to the flight conditions by changing the geometry of the wing, horizontal stabilizer and controls the flight. The fuselage is equipped with a guide with lock, booster and sash, allowing to cover the mentioned guide, the wing is designed as a trapezoidal wing with a small extension, consisting of a fixed arrow-shaped parts with high aspect ratio and triangular parts with high aspect ratio, having a spar at the root portion, made with the possibility of rejection by the booster down and back. Trapezoidal wing is equipped with a hinge, designed for connection near the tips mentioned arrow-shaped and triangular parts. The spar is made with the possibility of telescopic extensions when moving the booster along the guide retainer. The invention is aimed at improving the efficiency of adaptation of the aircraft to the various flight modes. 3 C.p. f-crystals, 5 Il. The invention relates to the field of aircraft, namely the aerodynamic characteristics of supersonic aircraft on RA is e is intended for effective braking maneuvers, in particular in the field of military aviation. On take-off and landing modes, it is possible to create a powerful wing configuration that will allow the aircraft with good thavarungkul or accelerating the engine to safely fly at low speed, almost without changing the angle of attack of the entire plane. Now for supersonic flight effective is trapezoidal wing almost right angle rear edge and for subsonic - swept wing. Best so far is a compromise trapezoidal wing with a swept trailing edge that is used on such aircraft as the MIG-29, SU-27, F-15 and. so on, as a prototype of the selected aircraft of this class, in particular the invention (patent RU 2140376. Subbotin centuries, Blinov A. I.) related to multimode, maneuverable aircraft, able to adjust aerodynamic surfaces to different flight modes. However, minor changes mentioned surfaces is no longer enough to create next-generation aircraft. Known circuit braking of the aircraft in the air, by rejecting triangular wing tips offered on a small sports plane (application of UK 2237254. Barnard Richard). However, the greatest is their corkscrew. On take-off and landing modes are known with the idea to use two rectangular wings, one of which is rotary mounted below the front stationary, to create a single landing circuit (patent of Russia 2121940. Kiriakidi S. K., A. Panov Century, Chistov S. Century). A small plane is not effective due to the complexity of the design and weight, as well as the ability to reach for aircraft of this class is similar TOLC conventional methods. The invention has the above-mentioned possibilities of adaptation of the aircraft to the various flight modes on a higher and more effective level. The invention is explained in the description with reference to the accompanying drawings and graphics. Fig. 1 - type of aircraft in subsonic flight mode, moved down triangular part of the wing. The dashed line shows the supersonic configuration. The arrows indicate the possible relocation of a triangular wing. Fig.2 - type of aircraft in landing configuration. Fig. 3 is a diagram of a telescopic extension spar triangular part in the area of the swivel with swept part of the wing. Fig. 4 is a diagram version of the aircraft with articulated joint is of disobedience CX wing with different movements of the wing at subsonic and supersonic Mach numbers. On the plane normal aerodynamic scheme (Fig. 1) has a trapezoidal wing, consisting of the arrow-shaped front fixed part 1 and the triangular movable rear part 2, which can move down and back along the sidewall of the fuselage, being pivotally connected with the swept part of the wing in the area of the ends. This is ensured by the fact that the side member 5 (Fig. 3) triangular wing made telescopic, i.e., extends in the lower position, where the fixed and at the same time can serve as a brace for the swept portion of the wing, which increases the rigidity of the whole structure in subsonic, most maneuverable, the areas of the flight. Guide triangular wing is located on the side of the fuselage across the air flow, so it is covered by the shutter-plate 4 (Fig.2) advanced forward on the wing changes. On the graph (Fig.5) shows the dependence of the lift coefficient of the su from the resistance coefficient CX wing, changing its extension in flight withkr= 4.3 subsonic regimes tokr= 3.3V at supersonic (thesis Abdykarimov M. A., head, I. Shatalov And MAI, 1986). From the graph we see that the polar when t;1 exceed the ratio su/Sh in subsonic configuration. Approximately theoretical background and constructively manage to implement the present invention. Triangular part of the wing can be rotated a positive angle around the axis of the spar, floating along with it inside the fuselage for the common rail pivot mechanism. When a sudden this turn, as in the one with the arrow-shaped part of the wing, and in the lower position, it is possible to achieve a sharp deceleration of the aircraft to compensate for the work of the horizontal tail the resulting torque. The landing configuration (Fig.2) may be carried out without turning the triangular portion of the wing 2, but with the released flap 3 with swept wing 1, for example, for large type aircraft "Concorde" and turning, then guide the triangular part of the wing should reject it down and back a little, to create a single path: the swept part of the flap was rotated triangular part of the wing, which contributes to a significant increase in the lifting force without a major change in the angle of attack of the entire plane. In the case of combat aircraft, this circuit creates unlimited possibilities for tactics and combat use in combination with other vozmojnostyami each other, a compact and technologically similar to some systems housekeeping issue of the chassis. Therefore, this adaptive wing can be placed on the existing MIG-29, SU-27-37, F-15. In the circuit of Fig.4 shows a variant of aircraft on which to place the Aileron hinge connection parts of the wing are made at some distance from the ends of the swept wing. In civil aviation, aircraft type, "Concord", you can use this wing in the above embodiment, that is, without turning triangular part of the wing, thereby simplifying the design to improve the reliability of system adaptation. The transition of the wing with supersonic regime at subsonic happens here on a large, close to the cruising altitude of flight, which also affects the safety of the flight. Subsonic configuration contributes to the landing not on such high angles of attack, as the "Concorde, Tu-144, which promotes the use of aerodromes different classes and reduces restrictions on pogodnosti. Increases thus, flight safety, which may indirectly lead to higher projected passenger capacity. All these factors will lead to the most cost-effective passenger versuses, wing, means of mechanization, designed to adapt the wing to the flight conditions by changing the geometry of the wing, horizontal stabilizer and controls flight, characterized in that the fuselage is equipped with a guide with lock, booster and sash, allowing to cover the mentioned guide, the wing is designed as a trapezoidal wing with a small extension, consisting of a fixed arrow-shaped parts with high aspect ratio and triangular parts with high aspect ratio, having a spar at the root portion, made with the possibility of rejection by the booster down and back, trapezoidal wing is equipped with a hinge, designed for connection near the tips mentioned arrow-shaped and triangular parts, the said spar is made with the possibility of telescopic extensions when driving booster guide with lock. 2.
