ABSTRACT:
An arrangement for aerodynamically braking the rotational movement of a body, especially a secondary or subordinate ammunition member which is ejected from its carrier, through the utilization of flexible braking surface elements which are articulated to the wall of the body so as to be swingable outwardly. A flexible braking surface of that type can be simply configured as a sheet metal plate or fabric which is pliantly bendable in every direction, which allows it to be slung about the wall of the member so as to closely lie thereagainst, and thereby protrudes only slightly; but which, on the other hand, because of its weight (and at times through a weight exerting a centrifugal force, which is additionally attached at its end) will dependently and rapidly unfold when there is released its restraint from its initially rolled-up condition; for example, when the member is to be expelled from its built-in position within a carrier.
