LIGHT TWIN-ENGINED AIRCRAFT Russian patent published in 2010 - IPC B64C3/58 B64C3/32 B64C13/00 

FIELD: aircraft engineering.

SUBSTANCE: proposed aircraft represents a low-wing monoplane with engines mounted on wing (2) attached to lower surface of airframe (1). Tail unit consisting of fin (8) with rudder and tailplane (9) with elevation rudder is arranged at airframe rear. Aircraft landing gear consists of front leg (6) and main legs (7). Engine nacelles (10) feature bearing aerodynamic profile. Lower surface of engine nacelles make a continuous continuation of wing lower surface. Engine nacelles represent wing aerodynamic fence. Engine nacelle flat side surfaces (13) are arranged perpendicular to wing surface. V-like wing and flaps joint is arranged along lengthwise axis of airframe. Note the flap extension mechanism (19) is also mounted along aforesaid axis. Extending rod of aforesaid mechanism couples cranks (21, 22) of RH and LH outer wing flaps. Wing and flaps lower surface form continuous lower surfaces of the airframe that feature two-face shape with cross section equal to that of the wing and extending till aircraft tail unit.

EFFECT: higher aerodynamic properties.
