CONFIGURATION OF AIRCRAFT WITH IMPROVED AERODYNAMIC CHARACTERISTICS Russian patent published in 2007 - IPC B64C1/00 B64C23/06 

FIELD: aviation.

SUBSTANCE: aircraft (10) has fuselage (12) connected with wings, air intake (46), nose section (52) of fuselage of varying cross section and vortex generation control unit (72) located on leading-edge wing extension whose shape makes it possible to make symmetrical break of vortices on said extension and medium and large angles of attack; it is engageable with tail sections (44 and 38) spaced apart so that leading edge (36) of vertical fin (38) gets beyond trailing edges of each wing for maintenance of stability in transversal direction. Ratio of area of leading edge extension and height of vortex generation control unit is equal to 2.35 m and tolerance range changes from +100% to -50% of this magnitude.

EFFECT: improved aerodynamic properties at large angles of attack.
