Figure 30 shows the percentage of malfunction-turn impacts in 5° sectors for no breakup, and for breakup qa’‘s of 20,000, 10,000, and 5,000 deg-Ib/ft’. The three breakup qa‘s produced impact distributions that were surprisingly similar, possibly due to the vehicle’s higher acceleration. Theoretical Mode-5 impact distributions are also plotted in the figure for B = 1,000 and 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. For all except the no-breakup case, values of A were found that produced good fits between the malfunction-turn and Mode-5 impact distributions in the sectors from +60° to +180°. 100 Percent in 5-deg sector (%) 0.01 i | _t al i i i i 0 20 40 60 80 100 120 140 160 180 Angle From Flight Path (deg) Figure 30.
