Braking arrangement for a correctable-trajectory spin-stabilized artillery projectile

Abstract

In order to provide that the braking elements ( ), which are to be deployed radially under the effect of centrifugal force, of the braking arrangement in the region of the ogival head of a spin-stabilized artillery projectile ( ) are secured in the rest position and can then be released in a defined manner when reaching the braking point of the ballistic trajectory, the stowage space ( ) for accommodating the braking elements ( ) is radially covered by a hood ( ) which is fitted on to the projectile fuse ( ) in the afflux direction and is axially fixed between a recess ( ) in the rear wall ( ) of the stowage space and a front-end holding ring ( ) connected to the ogival head. To release the braking elements ( ) the more solid front annular region ( ) of the hood ( ) is blown off radially by means of pyrotechnic force elements ( ) and therewith the hollow-frustoconical hood wall is broken open rearwardly, over the stowage space ( ), along desired-rupture locations, to form shell portions which are approximately parallel to the axis and which are then firstly pivoted outwardly in a rotational movement hinge-like in the recess ( ) by the afflux flow and are finally flung away. In that way the solid or textile braking elements ( ) which are fitted into the stowage space ( ) can now be deployed out of the stowage space into their radial operative position under the effect of centrifugal force, pivoting about their pivotal mounting to a ring ( ) in the front region of the stowage space ( ).
