Abstract

Ein Klappflügel für einen Flugkörper umfasst eine mechanische Antriebseinrichtung zur Entfaltung des Klappflügels nach dessen Freigabe. Als Antrieb wird eine vorgespannte Spiralfeder (20) verwendet, welche mit einem Zugseil (21) gekoppelt ist, welches über einen doppelten Flaschenzug (2,3) geführt wird.
Der Klappflügel besteht aus einer Flügelwuzzel (13), einer inneren Flügelfläche (12) und einer äußeren Flügelfläche (9).

A folding wing for a missile comprises a mechanical drive device for unfolding the folding wing after its release. As a drive biased coil spring (20) is used, which is coupled to a pull rope (21), which is guided over a double pulley (2,3).
The folding wing consists of a Flügelwuzzel (13), an inner wing surface (12) and an outer wing surface (9).
