| Abstract: | The launch of a large-size spin rocket can be modeled as the spitial binding system for a varying stiffness flexible rotor under constant thrusts,Coupled partial differential equations of longitudinal and transverse vibrations are established.The numerical solution is given for dynarnic response and parameters,behavior during launch by means of finite elementgeneralized calculus of variations. |
