For each mode ( i ), the forced oscillator equation is: [ \ddot\eta_i + 2\zeta_i\omega_i \dot\eta_i + \omega_i^2 \eta_i = Q_i(t) ] Where ( Q_i(t) ) is the generalized force: [ Q_i(t) = \int_0^L \phi_i(x) \cdot p(x,t) , dx ] ( p(x,t) ) includes distributed aerodynamic loads and concentrated engine thrust.
Imagine this scenario:

The equations of motion for a flexible rocket can be derived using the following steps: For each mode ( i ), the forced
Let us walk through a high-level simulation logic. Note: This is the type of pseudo-code you would find in an appendix of a good simulation PDF.
