MULTI-PURPOSE VERTICAL TAKEOFF AND LANDING AIRCRAFT Russian patent published in 2006 - IPC B64C29/00 B64C27/28 

FIELD: aeronautical engineering.

SUBSTANCE: proposed aircraft is made according to flying eing configuration. Aircraft has fuselage 1, wing 2, power plant with two engines located in nacelles 3, three tilt propellers in channels 10 equipped with tilt units and V-shaped tail unit 4. Wing 2 has W-shaped form in plan with outer panels of different sizes: swept-forward outer panel 7 and swept-back outer panel 8. Two tilt propellers are mounted in front of V-shaped bends in plan of leading edge of swept-forward outer panels 7 of wing 2 and one tilt propeller is mounted between nacelles 3 in rear part of wing 2. Lateral sides of trapezoidal form in plan of control surface 17 are made in form of extension of trailing edge of swept-forward outer panel 7 of wing 2.

EFFECT: reduction of induced drag of propeller-wing system; enhanced aerodynamic property; improved takeoff and landing characteristics; ease in longitudinal control.
