  • Leontiev M.K., Davidov A.V., Degtiarev S.A., Ivanov A.V., Modeling and analysis of dynamic characteristics of turbopumps with annular seals
    Turbopumps with annular seals The general methodology of analysis of turbopumps with annular seals at linear and non-linear statement is presented. For annular seals with floating rings the algorithm allowing consideration of hydrodynamic forces, rings inertia and friction forces is developed. The results of analysis of the turbopump rotor system with annular seals and their influence on vibration characteristics of the rotor system are presented.
