MECHANISM FOR KRUGER-FLAP DRIVING

摘要

The invention relates to a Kruger-Flap driving mechanism which determines the increase of the buoying force or protects the laminar flow on the wing rear, being used in aeronautic field for driving the hypersustentation devices and in any situation in which the rotation axis cannot be materialized. According to the invention, the mechanism consists of an electric or hydraulic actuator (5) which drives the arm (1) about an axle (9) integral with the rib (6) and drives the arm (2) by means of the axle (10) integral with the shaft, the arm (2), by means of the axle (11) drives the Kruger-Flap (3), the arm (7) which is symmetrical to the arm (1) as against the plane of rib (6), is rotated about the axle (13) and entrains the arm (8), by means of the axle (14), which, by means of the axle (12) drives the Kruger-Flap (3), the pairs of arms (1 with 7, 2 with 8) and of axles (9 with 13, 10 with 14 and 11 with 12) being symmetrical, and upon reversing the rotation direction of the actuator (5) there takes place the reverse movement of the Kruger (3).
