| Zusammenfassung: | 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).
Invenţia se referă la un mecanism de acţionare Kruger-Flap, ce determină creşterea coeficientului de portanţă sau protejează curgerea laminară pe extradosul aripii, fiind utilizat în domeniul aeronautic, la acţionarea dispozitivelor de hipersustentaţie şi în orice situaţie în care axa de rotaţie nu poate fi materializată. Mecanismul conform invenţiei este constituit dintr-un actuator (5) electric sau hidraulic, ce acţionează braţul (1) în jurul unei axe (9) solidare cu nervura (6), şi acţionează braţul (2) prin intermediul axei (10) solidare cu axul (1), braţul (2), prin intermediul axei (11), acţionează Kruger-Flap-ul (3), braţul (7), care este simetricul braţului (1) faţă de planul nervurii (6), se roteşte în jurul axei (13) şi antrenează braţul (8), prin intermediul axei (14), care, prin intermediul axei (12), acţionează Kruger-Flap-ul (3), perechile de braţe (1 cu 7, 2 cu 8) şi de axe (9 cu 13, 10 cu 14 şi 11 cu 12) fiind simetrice, iar la schimbarea sensului de rotaţie a actuatorului (5) se produce mişcarea inversă a Kruger-ului (3). |
