Flexible rockets exhibit coupled structural and flight-dynamics behavior that can degrade stability and control if not properly modeled. This article reviews modeling approaches for structural flexibility, fluid–structure interaction, actuator/servo dynamics, and sensor placement; derives equations of motion for a flexible multibody launch vehicle; describes linearization and modal reduction techniques; details typical simulation workflows; and presents example results illustrating stability margins, bending modes, and guidance–control interactions. Recommendations for validation and guidance for software implementation are provided.
introduces complex interactions between the vehicle's elastic modes, its control systems, and external forces. This report explores the mathematical formulations required to model flexible rockets, the critical coupling phenomena involved, and the modern computational methods used to simulate their flight. 2.
