THE DYNAMIC RESPONSE OF ADVANCED VEHICLES

An analytical study program has been conducted in order to determine dynamic load conditions and governing parameters for the flight of advanced vehicles; and an assessment of the adequacy and the applicability of existing dynamic loads prediction methods has been made. A typical two stag liquid fuel boost-glide configuration is assumed for the study, thus allowing for the interaction of such variables as fuel slosh, structural flexibility, aerodynamic forces and control system forces. The report is divided into sections which discuss dynamic loads in the following areas: pre-launch, launch, boosted flight, staging, re-entry and landing or recovery. Included in the Appendices are discussions of modal determination, simplified methods of analysis, computation techniques, and ground wind criteria. Also included is a development of flight equations of motion and an extensive bibliography of reference material.
