Abstract
Liquid propellant engines are widely used in satellite launching vehicles for providing a high level of energy and the ability to control the thrust intensity. These engines require efficient propellant pumping systems. High-powered engines operate under high pressure in the combustion chamber and thus, fuel and oxidant must be injected at high enough pressures. Turbo pumps can pump propellants with the required pressure level. The rotor of a turbopump rotates at thousands of revolutions per minute and is subject to the vibrations inherent to its operation and also to the dynamic loads arising from the launch vehicle's trajectory. In this work, the effect that flight maneuvers of a satellite launching vehicle have on the transverse vibrations of a turbine pump rotor is analyzed. A rotor dynamics model with flexible shafts and hard disks was modeled and implemented in numerical computing software to perform the analysis.
