Abstract:

The wind induced responses of the Saturn C-5 without fins are calculated with three aerodynamic representations. The most accurate representation uses unsteady aerodynamics and accounts for penetration into the gusts. The second uses pseudo steady aerodynamics and accounts for penetration. The third uses pseudo steady aerodynamics and assumes equal wind cross flows over the missile length. The responses, which include two sloshing and two bending modes, are affected by penetration to a detectable but insignificant degree. The use of unsteady aerodynamics causes very little change. The conventional, third aerodynamic representation provided in these cases slightly conservative large responses.
