BSU-11A/B Conical Fin IOT and E (Constant Bracket).

摘要

The BSU-11A/B Conical Bomb Fin was designed as a replacement for the MAU-93/B Fin currently used on the MK 82low drag general purpose bomb. The purpose of this evaluation was to determine the operational suitability,effectiveness,and limitations of the BSU-11A/B,with emphasis on comparing it to the MAU-93/B. Testing,consisting of manual deliveries of inert MK 82bombs with BSU-11A/B and MAU-93/B fins,was made at dive angles of 15, 30,and 45deg on the Nellis ranges,and a dynamic stability study was performed. Additionally,all aspects of ground handling and buildup were evaluated,including a timed build-up test and an F-111aircraft fit check. It was concluded that the quickattach bolt and clamp mechanism of the BSU-11A/B was unsatisfactory for field use. Statistically,there were no significant differences in dispersion and accuracy of the BSU-11A/B and the MAU-93/B;however,variation in ballistics may become significant in high-time-of-flight deliveries. Stability characteristics were the same;and a 44percent build-up time was saved with the BSU-11A/B.
