AIRCRAFT Russian patent published in 2002 - IPC

FIELD: aeronautical engineering; manufacture of multi- fuselage aircraft. SUBSTANCE: aircraft has two fuselage located in horizontal plane at some distance from each other, three aerodynamic lifting surfaces in form of front wing, main wing and stabilizer, engines, crew cabin and compartments for passengers and/or cargo/internal lateral surfaces of fuselage, inter-fuselage lifting surfaces and engines arranged between fuselages are so located that they form semienclosed aerodynamic passage-air intake. Fuselages have straight or concave internal lateral sides. Wings (more than two wings may be provided) are located relative to each other at levels ensuring direction of air flow along passage-air intake to engine diffusers mounted at the top of lifting surface or under it. Aircraft may be provided with third fuselage located between two fuselages and provided with flat or concave lateral sides, with flat bottom and top. Aircraft may be according to "tailless aircraft" configuration with main swept-back or swept-forward wing. EFFECT: possibility of manufacture of aircraft of various modifications and purposes flying at subsonic and supersonic speeds at enhanced reliability and efficiency. 4 cl, 3 dwg
