SUPERSONIC AIRCRAFT Russian patent published in 2021 - IPC B64C30/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aviation, in particular to long-range supersonic administrative aircraft. A supersonic aircraft contains a fuselage, the nose of which is deflected downwards with respect to the horizon, a swept V-shaped wing, a nacelle with a power plant located in it, consisting of two or more engines with overwing air intakes and a nozzle. At the same time, the nose part of the fuselage before the wing strake is made in the form of a profiled body of rotation with an elongation of 8-12 and is deflected downwards by an angle of 3-5° with respect to the horizon, the root part of the wing is made with a transverse V angle equal to 9-12°, and is smoothly mated with the fuselage by means of a wing influx with a leading edge of continuous curvature, the end part of the wing is made with a transverse V angle equal to 0-7°.

EFFECT: developing an aerodynamic layout of an aircraft that ensures the achievement of high aerodynamic characteristics in cruising flight, an acceptable sound impact level for flying over land without restrictions and the reduction of the noise level in the airport area at take-off and landing modes.
