AIRCRAFT WITH LIFTING FUSELAGE Russian patent published in 2001 - IPC

FIELD: aviation; designing wide-fuselage aircrafts. SUBSTANCE: aircraft has lifting fuselage, wing and engine. Width of fuselage exceeds its height and their ratio may be equal to or more than 2. Lower surface of main and tail sections of fuselage has concavity inside fuselage in cross section. Lower surface of flatted from section of fuselage is mounted at an angle of attack relative to longitudinal horizontal plane which is equal to or more than 4 deg, but angle of attack of 5-7 deg, preferably. Forward fuselage has curvilinear shape in plan which may be close to S-shaped form changing from narrow nose section towards wide main section of fuselage. Tail unit is made in the form of two fins spread in width of fuselage away from longitudinal vertical plane of aircraft mounted at angle relative to said vertical plane. Longitudinal vertical sections of fuselage may have configuration of aerodynamic profiles mounted an angle of attack equal to or more than 2 deg in each section. Tail fuselage may have surface deflectable relative to horizontal axis of rotation. Angle of each fin relative to vertical plane may be equal to or more than 10 deg, but angle of 20 dwg is preferable. EFFECT: improved characteristics of wide-fuselage aircraft. 7 cl, 5 dwg
