Definitions

  • a simple means of correcting these deviances is to provide the munition with a means of altering its air resistance in flight in response to a deviation from some measured trajectory parameter
  • the GPS (Global Positioning System) receiver and logic unit can locate the position of the munition by triangulation with GPS satellites in known orbits around the earth as is well known in the art and can compare the evolving trajectory of the munition against a stored nominal trajectory.
  • This nominal trajectory can be based on a standard range and need not be programmed for separate firing locations although specific target locations could be chosen if required. Range corrections are effected by deploying the drag plates at differing times.
  • the munition is a spin stabilised munition and the deployment means comprises at least two retaining pins, the retaining pins being arranged so that at least one retaining pin passes through each drag plate in the undeployed configuration.
  • a retaining pin removal means is provided for removing the retaining pins from the drag plates on receipt of a control signal and the drag plates are freely slidable between the undeployed and deployed configurations such that, in use, removal of the retaining pins allows the centrifugal forces on the munition to cause the drag plates to slide to the deployed configuration.
  • Figure 1 shows a projectile having a drag means according to one embodiment of the invention
  • a spin stabilised projectile has a fuze 2 located forward of the payload volume 3
  • a drag means consisting of a forward base plate 20, two pairs of drag plates 22, 24 and a rear base plate 26.

Abstract

Moyen servant à augmenter la traînée d'un projectile, afin d'effectuer une correction de course, et possédant des paires de plaques de traînée (24, 26) à verrouillage réciproque situées dans le même plan et pouvant s'étendre latéralement depuis une configuration non déployée, sensiblement contenue à l'intérieur du projectile, vers une configuration déployée. Ces plaques de traînée (101, 103) sont pourvues de saillies (34, 38) et de fentes (36, 40), les saillies (34, 38) de l'une des paires de plaques de traînées étant conçues de façon à loger dans les fentes (36, 40) de l'autre plaque de traînée dans la configuration non déployée et à s'étendre à mi-course à l'intérieur du projectile. Un moyen de déploiement (60, 62, 70, 72) retient les plaques de traînée en configuration non déployée jusqu'à la réception d'un signal de commande, puis effectue le déploiement des plaques de traînée, la distance parcourue entre les configurations déployée et non déployée étant déterminée par la longueur des saillies (34, 38).
