MULTI-FUNCTIONAL TWO-SEAT STEALTH AIRCRAFT Russian patent published in 2023 - IPC B64C30/00 

FIELD: aviation.

SUBSTANCE: multifunctional two-seat stealth aircraft with an integral aerodynamic layout contains a complex of on-board equipment, a fuselage with an overflow, wing consoles with mechanization of the leading and trailing edges, including flaperons, ailerons and rotating wing tips, consoles of an all-moving horizontal and two-fin vertical tail unit mounted on the side tail booms of the fuselage, a two-seat a cockpit with a canopy, a garrot and a radome of the locator antenna, located in the forward part of the fuselage, a power plant with two engines spaced horizontally and equipped with air intakes, located in engine nacelles, the axes of which are oriented at an acute angle to the plane of symmetry of the aircraft in the direction of flight. The aircraft is characterized by the fact that the wing consoles are smoothly coupled with the fuselage, the fuselage overhang is located above the engine air intakes and includes controlled rotating parts, the aircraft engines contain a jet nozzle with a deflectable thrust vector and thrust reverser, the all-moving vertical tail is installed at an acute angle to the vertical plane of the aircraft, the console the wings are trapezoidal in plan with a large sweep along the leading edge with a sweep angle of 49° along the leading edge and with small values of relative wing thicknesses ranging from 3% to 5%, while the area for placing the cockpit, garrot and radar antenna fairing is formed by orienting the tangents to the contour of the cross sections of the fuselage at an angle to the plane of symmetry of the aircraft, and the shape of the surface of the cockpit canopy is formed with angles of inclination of the side tangents to the vertical plane of the aircraft in the range of 20°-30°, in the middle part of the fuselage between the engine nacelles there are payloads, as well as additional fuel tanks. On the upper surface of the cargo compartments there are attachment points for ejection devices for aviation weapons, while the complex of on-board equipment is designed with the possibility of information interaction between different types of aircraft of the group, including in terms of receiving and transmitting data via high-speed communication channels and group communication, including via satellite communication channels, as well as analyzing information coming from its own systems and external sources with the subsequent issuance of recommendations to the crew and/or commands to a group of aircraft, and the cockpit is equipped with controls to transfer control priority from one pilot to another and, according to at least two multifunctional panoramic indicators for controlling the aircraft and weapons.

EFFECT: invention makes it possible to reduce the level of visibility of an aircraft in the radar range, increase the maneuverability of the aircraft, increase the level of aerodynamic characteristics of the aircraft, expand the functionality of the aircraft in terms of information and communications interaction, including in the absence of satellite and long-distance short-wave communications, expand the range of weapons used, increase the flight range of the aircraft, as well as expand the range of altitudes and flight speeds.
