AIRCRAFT HORIZONTAL STABILISER SURFACE Russian patent published in 2015 - IPC B64C5/02 B64C1/26 

FIELD: transport.

SUBSTANCE: surface (8) of aircraft horizontal stabiliser is made so that sweep angle (40) of surface (8) is the angle formed by projection of base line of points located on 25% of horizontal stabiliser surface (8) local chord (19) on a plane being perpendicular to aircraft symmetry plane (21). The plane contains aircraft flight direction relative to aircraft symmetry plane (21) and makes an angle of less than 90 degrees. The angle (40) is measured in direction of aircraft flight. Structural connection of horizontal stabiliser surface (8) with aircraft fuselage (1) is located on closing stiffening ring (13) of fuselage (1). Structural connection between horizontal stabiliser surface (8) aircraft fuselage (1) contains additional connection (14) attached to central structure (16) of surface (8) which connection provides structural stability of this surface (8).

EFFECT: invention is focused on enhancement of horizontal stabiliser efficiency.
