- FIG. 3 is a bottom view of the aircraft
- FIG. 4 is a front view of the aircraft
- FIG. 5 - section A-A
- fig. 6 - section B-B fig. 7 - section B-B.
- the multifunctional single-engine supersonic aircraft is a monoplane made according to the "tailless" balancing scheme with a V-tail.
- the aircraft includes a fuselage 1, developed side beams 2, a trapezoidal wing, consoles 3 of which are smoothly connected with the fuselage 1, a V-shaped all-moving tail unit, consoles 4 of which are deflected from the vertical plane of the aircraft, a single-engine power plant, including an engine with a jet rotary nozzle 5, located along the axis of symmetry of the aircraft in the engine nacelle.
- Console 3 of the trapezoidal wing is smoothly mated with the fuselage 1 and is equipped with mechanization of the leading and trailing edges, including swivel socks, elevons, flapperons.
- the mechanization of the trapezoidal wing is used to provide control in the roll and pitch channels, improve aerodynamic quality, and also to increase lift.
- Consoles 4 of the V-shaped all-moving tail mounted on pylons, deflected from the vertical plane by an increased angle, preferably 12° - 50°, and perform the functions of both horizontal and vertical tail, providing the necessary characteristics of stability and controllability of an aircraft that does not have a horizontal tail .
- an all-moving tail unit is used, which combines the functions of vertical and horizontal tail unit.

- a lower-side air intake with a channel bent in a vertical plane which changes the cross-sectional shape from U-shaped to round, makes it possible to exclude direct visibility of the inlet guide vane of the engine and further reduces the RCS of the aircraft in the front and side views, and also makes it possible to place under the lower-side air intake the central cargo compartment is large and ensures stable operation of the engine in all flight modes of the aircraft.
- the location of the niches of the main landing gear behind the side cargo compartments allows you to reduce the midsection area, while allowing you to get a significant amount of side cargo compartments, providing accommodation in them of bulky cargo. This ensures a reduction in the number of cargo compartments while maintaining the possibility of placing the same amount of bulky cargo in comparison with known analogues.
- the proposed design and arrangement of the cargo compartments and niches allows them to be made with a large volume while maintaining the small dimension of the aircraft and even reducing the geometric dimension of the aircraft.
- the presence of cargo edemas of a large volume ensures the placement of bulky cargo for various purposes, due to which the aircraft has versatility.
- the side surfaces of the lower parts of the side of the aircraft and the outer side surfaces of the all-moving tail are deflected by the same angle from the vertical plane of symmetry of the aircraft (see Fig. 4).
- Such an orientation of the aircraft elements contributes to the reflection of electromagnetic waves falling on the airframe elements from lateral angles into the upper and lower hemispheres, thereby reducing the overall level of the aircraft EPR in the lateral hemisphere.
- the claimed multifunctional supersonic single-engine aircraft is a new technical solution for volume-weight and structural-power layout and is a light tactical aircraft with high key characteristics: low weight and geometric dimensions, low visibility in the radar wavelength range, high flight performance. and maneuvering characteristics, due to which it performs tasks in a wide range of altitudes and flight speeds.
