A tail fin assembly for a guided projectile which is capable of withstanding the high pressures experienced during launch, which is also capable of stabilizing the projectile during initial flight shortly after emergence from the cannon or large gun barrel and which is also capable of freely spinning relative to the projectile front section for the remainder of the flight to minimize projectile roll to accomplish all of these capabilities sequentially during a single launch. The assembly includes the projectile and a rotatable member, preferably a tail f...
[ What is claimed is:] [19.] An apparatus comprising:a projectile;a member;a bearing structure supporting said member on said projectile for relative rotational movement about an axis which extends approximately parallel to a direction of travel of said projectile, and for relative axial movement;a locking structure operable to prevent said member from moving axially or rotationally with respect to said projectile in a locked mode of operation which is effective prior to and during a launch of said projectile, and operable to permit said member to move r...
