To suppress excessive vibrations for Rocket engine Turbopump, the design method is focused only the rotational system to considering the dynamics for impeller, turbine, seal and bearing. We are searching to confirm the multidisciplinary optimum design method which, based on the dynamics for rotational system elements in turbopumps.
