FIELD: aeronautical engineering. SUBSTANCE: proposed aircraft has fuselage, wing, high-lift devices for adaptation of wing to flight conditions through change of wing geometry, horizontal tail and flight control devices. Fuselage is provided with guide fitted with retainer, booster and door for partial closing of said guide; wing is tapered in shape at small aspect ratio; it consists of fixed swept portion at considerable aspect ratio and triangular portion at considerable aspect ratio; it has spar in wing root for up and down deflection by booster. Taper wing is provided with articulation for connection of tips of swept and triangular portions. Spar is telescopically elongated at motion over guide. EFFECT: enhanced efficiency of adaptation of aircraft. 4 cl, 5 dwg
