Abstract: The invention relates to multimode aircraft operated at supersonic and subsonic flight speeds in a wide range of flight altitudes. The invention is particularly applicable in multimode super-maneuverable aircraft capable of cruising at supersonic speed and having low radar signature. The technical effect to be achieved by the invention is to provide an aircraft which has low radar signature, is super-maneuverable at high angles of attack, has high aerodynamic efficiency at supersonic speeds while keeping high aerodynamic efficiency at subsonic modes, and can accommodate bulky cargo in its internal compartments. The integral aerodynamic configuration aircraft comprises fuselage (1) with strake (2), wing with panels (3) smoothly blended into fuselage (1), all-moving horizontal tail (AMHT) (4), and all-moving vertical tail (AMVT) (5). Mid-fuselage is flattened and formed longitudinally by a set of aerodynamic profiles.

Abstract: The invention relates to aeronautical engineering and, more specifically, to air intakes for supersonic aircraft propulsion systems. The technical result to be achieved by the invention consists in ensuring stable operation of the engine in all flight regimes up to the maximum Mach number of M=3.0 by adjusting the apex angle of stages of one of swept wedges and minimum area of the flow passage of the air intake. An adjustable supersonic air intake comprises an entrance in the form of a flow deceleration system—a supersonic diffuser (22) consisting of two multi-stage swept decelerating wedges (7) and (20) which form a dihedral angle; a shell, which also forms a dihedral angle, all edges of the entrance lying in the same plane; an air intake throat situated downstream of the deceleration system, and a subsonic diffuser (23), downstream thereof. As seen from the front, the entrance of the air intake has the shape of a rectangle or a parallelogram.
