Abstract
In order to provide that the braking elements (16), 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 (12) 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 (14) for accommodating the braking elements (16) is radially covered by a hood (22) which is fitted on to the projectile fuse (11) in the afflux direction and is axially fixed between a recess (24) in the rear wall (25) of the stowage space and a front-end holding ring (26) connected to the ogival head. To release the braking elements (16) the more solid front annular region (28) of the hood (22) is blown off radially by means of pyrotechnic force elements (19) and therewith the hollow-frustoconical hood wall is broken open rearwardly, over the stowage space (14), 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 (24) by the afflux flow and are finally flun…
