<p>The hinge mounting is for a guidance mechanism, partic. of a missile or flying object, having folding guide fins each on a bracket. These swing out from a rest position inside a chord of the missile outline about a first axis at right angles to this chord into an intermediate position, and from the latter about a second axis into the flight position in a radial plane passing through the lengthwise axis of the missile, being controlled by a sliding member so that they remain permanently in the plane of the chord. Each bracket (2) has a pivot sleeve (31) on which the fin (1) hinges about the first axis (A) in direction P1. The sleeve turns on a bush (28) fixed to the missile body about the second axis (B), and which has a guide slot (29) centred on the second axis, causing the fin to turn on the first axis and the sleeve to turn on the bush.</p> |
