4.7.5 6 DOF Monte Carlo Analysis
Atmospheric winds generated from EarthGRAM and a 3 DOF parachute model were added to the POST
II model used for the stability analysis. The dispersions given in Table 13 were used to complete a 250
run Monte Carlo analysis on the higher fidelity model. The results are given below. As seen in Figure 31,
Figure 33, Figure 35, and Figure 37 all cases are stable since the total angle of attack remains bounded.
These figures also indicate relatively low impact velocities. However a more detailed analysis is needed
