Fluid Dynamic - Structural Interactions of Labyrinth Seals.

reportActive / Technical Report | Accession Number: ADA174780 | Open PDF

Abstract:

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 Labyrinth Seals Force Coefficients Rotor Dynamics.
