The holy grail of flexible rocket simulation is the nonlinear coupled ODE:
In this post, we are going to strip away the dense math and look at the core concepts: Why rockets bend, why that is dangerous, and how simulation saves the day. dynamics and simulation of flexible rockets pdf
A simulation is only as good as its captured physics. In flexible rockets, several elements are highly coupled and must be modeled together: Dynamics and Simulation of Flexible Rockets - Perlego The holy grail of flexible rocket simulation is
