Modern launch vehicles are designed to be as lightweight as possible to maximize payload capacity. As a result, rockets are inherently flexible structures, characterized by long, slender bodies and large liquid propellant tanks. When these flexible systems undergo rapid maneuvers or experience intense aerodynamic loads during ascent, they exhibit structural bending that directly interacts with the flight control system. dynamics and simulation of flexible rockets pdf

High-fidelity simulation architectures use a co-simulation approach to solve these coupled governing equations. Meeq̈+Ceq̈+Keq+Merẍr=Fecap M sub e e end-sub q double

As space missions become more ambitious—requiring taller, more slender launch vehicles and heavier payloads—the assumption that a rocket is a perfectly rigid body is no longer sufficient. Modern aerospace engineering must account for , where the rocket bends, vibrates, and deforms under extreme aerodynamic and propulsive loads. where the rocket bends
