Abstract: The inherent limitations of load capacity and stability of hydrodynamic gas-lubricated bearings can be reduced by introducing external pressure and creating a hybrid bearing. Numerical computerized ...

Abstract: The dynamic analysis of gas-bearing systems are discussed from two points of view. The “Time-Transient” method which has been previously reported in a number of papers [1] [2] couples the ...

Abstract: A numerical analysis for determining performance characteristics of hydrodynamic, hydrostatic, or hybrid bearings with arbitrary clearance distribution is presented. Solution of the Reynolds lubrication ...

Abstract: Helium buffered floating-ring seals used in cryogenic turbopumps are sujbect to large temperature variations, shaft centrifugal growth, and dynamic shaft excursions. To prevent dangerous contact ...

Abstract: This paper describes the development of two types of air-lubricated foil journal bearings, designed for separate purposes; stability and load capacity. The first was a three-pad configuration, ...

Abstract: The mechanical simplicity and damping qualities of fluid-film bearings makes them attractive possibilities for spool-shaft bearings of gas turbines. The simultaneous high-speed rotation of journal ...

Abstract: The concept of a fluid-equalized, tilting-pad thrust bearing is presented. Load augmentation is introduced by external pressurization through the pad pivots. Performance characteristics were obtained ...
