Figure 39: GT <strong>RASCAL</strong> Mission Profile.<br />
The trajectory plots for the GT <strong>RASCAL</strong> vehicle follow as Figure 40 and Figure<br />
41. As these plots show the trajectory of the GT <strong>RASCAL</strong> is very similar to that of the<br />
baseline. The major differences are, as already noted, that the first stage releases the<br />
upper stages with much more energy and that the third stage puts the fourth stage and<br />
payload in a lower transfer orbit, where fewer losses incur. These plots also show the<br />
tendency of the MIPCC engines to peak in thrust when the fuel flow rate of the LOX and<br />
water is at its highest (~94% of SLS thrust). When this occurs the Isp of the MIPCC<br />
engines plummets due to this same increased flow rate.<br />
