The Effect of a Shrouded Tail Extender on the Flight Characteristics of Bluff 500-Pound-Class Conformal Bombs.
Abstract
A fineness-ratio two cylinder with modified box fins (called star fins) was proposed as a 500-pound class general purpose bomb suitable for conformal carriage on aircraft. Model and full-scale free-flight tests of the proposed shape showed that it was subject to pitch-yaw-roll interactions that developed into large-angle (45 degrees) coning motions. The configuration was modified by extending the fin assembly 1.3 diameters aft with a shroud and removing a front tending the fin assembly 1.3 diameters aft with a shroud and removing a front spoiler plate. The modified shape flew much more smoothly and with much less angular motion (generally 7 degrees or less). Both the original and modified shapes separated cleanly from the carriage aircraft (ejected by an Aero 7A rack from level flight near 3000 feet).
