Patent Images
1. A frangible tail boom for a gun-launched projectile, comprising:
- a tail boom housing having a central longitudinal axis, a forward end configured to engage a projectile body and a through bore;
the tail boom housing having a forward portion and a rear portion, the forward portion having the general shape of a conical frustum, an outer diameter of the forward portion decreasing from the forward end toward the rear portion;
the through bore in the forward portion including a large diameter segment and a small diameter segment located rearward of the large diameter segment;
the forward portion including a circumferential groove extending from an outer surface radially inward toward the small diameter segment of the through bore wherein after the projectile impacts a target the tail boom is designed to fracture at the circumferential groove.
