INTEGRATED AIRCRAFT Russian patent published in 2009 - IPC B64C5/12 

FIELD: aeronautical engineering.

SUBSTANCE: proposed aircraft comprises a "wing-fuselage" assembly, cockpit, vertical and horizontal tail units, control surfaces, power plant, landing gear, aircraft and engine systems, equipment and instrumentation. The integrated aircraft tail part is formed by three movable surfaces arranged so that, in initial position, all said surfaces form a required geometry of the tail part. In the operating position two surfaces form a straight wing with elongation of at least λ>4 and feature symmetrical profiles with relatively great thickness of C=11 to 13%. The third surface is made up of sections with a negative concavity and extends for a distance equal to the maximum chord of this surface. All the said surfaces are articulated with the common pneumatic drive.

EFFECT: preventing spin stall.
