VERIFICATION OF A COMPUTATIONAL DYNAMIC MODEL OF A LAUNCH VEHICLE STRUCTURE
ABSTRACT
Problems of verifying launch vehicle (LV) models are investigated for analysis of the loads due to wind disturbances and the response of control units as well as variations of the structural dynamic characteristics as a consequence of intensive fuel consumption. The paper aims to discuss the problems of verifying LV structure models used for load analyses through demonstration of their reliability in describing the unsteady processes against the variations of the dynamic characteristics. Special attention is paid to evaluation of marginal load capacity in transient processes, taking into consideration possible scatterings with respect to the structural and aerodynamic parameters.
