6.3.1 Optimum Mode-5 Shaping Constants
The percentage of Delta vehicles that break up during simulated random-attitude turns
are plotted against failure time in Figure 23. The same breakup qa's used in the
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.
