LIGHT AIRCRAFT Russian patent published in 2007 - IPC B64C23/00 

FIELD: aviation; light multi-purpose aircraft.

SUBSTANCE: proposed aircraft has fuselage with tail unit and landing gear, engines with propellers and sectionalized wing formed by outer-wing panel and center-wing section. Aircraft fuselage is made in form of center-wing section at aspect ratio lesser than 0.5. At the bottom, fuselage changes to sectionalized wing with central part of low aspect ratio. To the right and to the left from fuselage, engines with propellers are mounted over chord of coupling of outer wing panels. Side surfaces of fuselage form propeller duct together with wing surface. Axes of rotation of propellers are located at distance relative to tail unit plane not exceeding 0.15 of propeller diameter.

EFFECT: improved aerodynamic characteristics of light aircraft; simplified construction; increased internal useful volume of fuselage.
