Figure 27 shows the percentages of malfunction-turn impacts in 5 sectors for no breakup and for breakup qa's of 20,000, 10,000, and 5,000 deg-lb/ft. For B = 1,000, theoretical Mode-5 impact distributions are also plotted in the figure using best-fit values of A. This value of B was chosen since it is currently used by RTI in making launch-area risk studies for 45 Sw/SE. Within the sectors from 60 to 180, where most population centers are located, data fits are reasonably good. As seen in the next figure, the divergence for the no-breakup case can be greatly reduced by selecting other values for B and A.. 100 TitanlVRandom-AttitudeFaitures.through.300:sec Breakup g-atpha in deg-lb/ft ..no.breakup 20,000 10,000 Percent in 5-deg sector (%) 5,000 10 B=1000 A=2.00 A=2.95 A=3.25 A=3.50 0.1 0 20 40 60 80 100 120 140 160 180 Angle From Flight Path (deg) Figure 27.
