Abstract : Tests were conducted to determine the effect of a 2 +/- 0.5 fin cant on the excessive yaw (up to 35 deg) of Ex 10 Mod 9 bombs. The yaw, which was not discernible on the modified bombs dropped from 20,000 ft at 140 to 160 knots (IAS), was estimated to be less than 5 deg as a result of the increased spin (12 rps) at impact compared to 0.11 rps for the unmodified bombs. The reciprocal ballistic coefficients were 0.116 for time of fall and 0.086 for range. The dispersion in range and deflection was 1.5 and 1.8 mils, respectively, and the average deflection was about 3 mils to the left. Flight tests showed no unusual flight characteristics imparted by the modified bombs to an F7F-3 aircraft at speeds up to 400 knots. (See also AD10730).
