ACTUATING MECHANISM FOR TRAILING EDGE FLAPS AND LEADING EDGE SLATS

摘要

An actuating mechanism for a trailing edge flap and/or a leading edge slat, comprising of pivot arms (4,20), a slide panel (8), an engine (1) actuating the movement of the trailing edge flap or the leading edge slat, and a screw mechanism (2). Due to a simpler construction, the devices described in this specification are more reliable and can be used on various aircraft from large UAVs and sailplanes to commercial airliners. The production costs of the described devices may be two times smaller and maintenance costs two to four times smaller than those of the devices used at present. By employing the devices provided in this invention, fuel consumption may be reduced, which also significantly reduces the operating costs of an aircraft. In addition, the weight of the leading edge slats and trailing edge flaps is reduced substantially compared to the devices known in the art.
