Abstract
The present invention relates to a method and a device designed for use with such shells ( ) that are equipped with a base-bleed unit ( ) for extended range and which during the first phase of their trajectory are spin-stabilised but which in the subsequent phase are subjected to spin deceleration by fins ( ) that deploy from the shell body and take over the stabilising function. More exactly the present invention is a method and a device that enables the said shells ( ) to achieve an effective and functional deployment of the fins ( ) at the desired point in time with simultaneous ejection of the base-bleed unit ( ) which at this point in time either no longer performs any useful function since it is burnt-out and solely constitutes a dead-weight or its function is no longer required. The basic idea behind the present invention is that the base-bleed unit ( ) and the fin protector ( ) that initially surrounds the fins ( ) shall be permanently integrated with each other and thereby can be removed/ejected as a single unit.
