“…In terms of aerodynamic forces and moments (Figure 17), the pressure increase induces an increase in the moment coefficient (C m,cg ), and a diminution of the normal (C N ) and axial (C A ) force coefficients. As indicated by Banyai et al in [7], the small values of C m,cg (Figure 17b) show that the vehicle is stable during the transitional portion of the reentry and the progressive increase toward a null value as it approaches the continuum regime ensures a stable transition towards the denser layers of the atmosphere. Finally, as envisioned by Banyai et al, for the altitudes greater than 100 km, the moment resulting from the aerodynamic forces might be incapable of counteracting the vehicle's possible inertia due to a disturbance.…”
