SUPERSONIC CONVERTIBLE AIRCRAFT Russian patent published in 2011 - IPC B64C30/00 B64C39/12 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Multipurpose supersonic convertible aircraft has airframe with low W-shaped wing smoothly conjugated with fuselage, power plant, wing nacelles, three-leg retractable landing gear with front and main legs. Proposed aircraft represents aerodynamic canard configuration with three pitch control surfaces. front horizontal tail, flaperons of center wing section and all-moving boards. Power plant comprises main and two extra turbojet bypass engines. It incorporates variable-sweep wings. Airframe is equipped with tail and wing boards, front horizontal tail and all-moving boards arranged on outer sides of two tail beams for braking, each provided with vertical tail fin. Fuselage features rhomb-shaped cross section, V-like truncated bottom and has belly flat air intake for engine. Wing has U-like extensions with swept fairings that form torsion box with suspension of three pitch control surfaces, central section with flaperons extending to wing nacelles and deflecting swept end sections mounted on nacelles. Top surfaces of tail and wing boards are coated with heat-resistant heat-absorbing material to reduced infrared radiation.

EFFECT: increased lifting capacity and flight range.
