Rockets are complex systems that consist of multiple components, including the structure, propulsion system, and control systems. The dynamics of a rocket are influenced by a variety of factors, including its mass distribution, stiffness, and damping properties. In traditional rocket design, the structure is often assumed to be rigid, which simplifies the analysis and simulation of the rocket’s dynamics. However, as rockets become larger and more complex, their structures become more flexible, which can significantly impact their performance and stability.
