Analysis of radial gaps changing dynamics of the pump and turbine rocket engine turbopumps

Abstract

The paper considers the factors influencing the change in the clearance of high-speed turbomachinery seals have been proposed for approximating the dependence of the gap analysis of changes in the operation of the unit. It is shown that for high-speed machines is undesirable during the design and analysis of turbomachinery using the assumption of constancy of the gap in all operating modes.
