ABSTRACT:
In order to move a textile braking element (16) which is in the form of an annular disk and which is deployed radially under the effect of centrifugal force rapidly into a contour which is stable in respect of shape and which is always properly defined even under afflux flow conditions, a cloth (33) which is cut in the form of a circular ring is provided by virtue of radially extending tucks or darts, with a reduced outside periphery (32) in such a way that the opening movement is thereby limited to the shape of a flat obtuse-angled hollow truncated cone which, by means of reinforcing bands (34) which are sewn on along generatrices of the frustoconical surface, is pivotably mounted to the holding ring (15) at the inside periphery (31) while along the outside periphery (32), it is provided with a peripherally extending accumulation of mass (29) for increasing the centrifugal deployment forces; wherein in the front end region of the stowage space (14), the ring (15) is axially fitted into the contour of the fuse (12), in such a way as to temporarily slip relative to the projectile spin.
