Fluid Dynamic - Structural Interactions of Labyrinth Seals

摘要

Work is described on a continuing investigation into the fluid dynamic and structural interactions of labyrinth seals. Three major areas are considered namely, (a) design and construction of a realistic labyrinth seal test rig to measure stiffness and damping forces in seals, (b) further development of an analytic labyrinth seal test model and its characteristics, and (c) formulation of a structural dynamic rotor system model including labyrinth seal forces and their application to the High Pressure Fuel Turbopump of the Space Shuttle main engine. Keywords: Layrinth Seals; Force Coefficients; Rotor Dynamics.
