6.3.1 Optimum Mode-5 Shaping Constants The percentage of Delta vehicles that break up during simulated random-attitude turns Atlas IIAS calculations were used here. It can be seen from the figure that over 50% of the vehicles break up, either immediately or eventually, if a turn begins between about 10 and 115 seconds. 100 Delta-GEM 90. q-alpha in deg-Ib/ft* 80 q-alpha = 5,000 Breakup Percent (%) 70 q-alpha = 10,000 60 : q-alpha = 20,000 50 40 30 20 10 0 0 40 80 120 160 200 240 280 Failure Time (sec) Figure 23.
