SUBSTANCE: invention relates to long-range executive aircraft. Proposed aircraft comprises airframe, sweptback wing, vertical tail unit, running gear and power plant made up of engines, air intakes and nozzles. Airframe front has flatted nose cone smoothly aligned with cockpit and passenger cabin with circular sections. Wing root front edge is rounded and smoothly aligned with airframe. Wing root rear edge has a break. Vertical rudder integrated with horizontal tail unit is arranged on tip of vertical tail extension. Wing features crosswise V angle. Supersonic air intakes are arranged above wing top surface on both sides of airframe, while, ahead of air intakes, both wing and airframe are a bit contracted. Ahead of air intakes, there are perforated sections for intake of boundary layer. Supersonic air intakes comprise mechanism of controlled air cross flows from boundary layer discharge channel into channel feeding air into engine. Supersonic nozzle critical section is arranged above airframe top surface between two vertical tail fins. Flat nozzle has rotary top flap. Airframe tail section changes into flat surface to smoothly terminate in elevation rudder. Tail elevation rudder comprises mechanism of down-displacement in take-off-landing conditions. Reverse rotary panel is arranged ahead of elevation rudder above airframe top surface. Channels for reverse lower jets are arranged below said panel.
