Dynamics stability of the MUSES-C sample return capsule has been assessed in the rarefied gas environments, from the free-molecular to transitional regime. Overall aerodynamic coefficients were determined by the empirical bridging method, and their accuracy was validated by a three-dimensional DSMC analysis of rarefied flows around the capsule. To obtain realistic aerodynamic coefficients in the DSMC analysis, nonequilibrium thermal relaxation and chemical kinetics were incorporated into the numerical model. The aerodynamic coefficients determined by the empirical formula are found to be in good agreement with those obtained by DSMC calculations. Rarefaction of the flow and position of the center of gravity of the capsule are found to have significant influences on pitching stability of the capsule. The six-degrees-of-freedom dynamics of the capsule was numerically simulated along the reentry trajectory to examine the effect of spin frequencies on stability of the capsule. |
