The modern standard for these simulations is to integrate with real-time flight software. For example, NASA's ARTEMIS simulation can track up to 30 different flexural modes simultaneously, ensuring the vehicle stays stable even as its mass changes rapidly during ascent. Recent studies even use fiber-optical sensors along the rocket's "spine" to measure bending in real-time, feeding that data back into the autopilot to adjust for unexpected vibrations.

Most simulations use variable-step Runge-Kutta (e.g., ode45 in MATLAB) or fixed-step solvers for real-time applications. The challenge: bending modes require small time steps (e.g., 0.001 s for a 10 Hz mode), making long-duration flights computationally expensive. This is where modal truncation is critical. dynamics and simulation of flexible rockets pdf
