F-0219 Study on gas bearings for micro gas turbines : Proposal of multilayered foil bearing

Abstract

Recently, it's recognized as a common knowledge that natural resources are exhaustible. From viewpoint of consuming limited resources, it is expected for cogeneration system to supply heat and electric power. This system keeps the possibility that CO_2 emission can be reduced. Though the majority of the working system is occupied with the large-scale system, introduction of a small-scale system is begun, so that high-performance and maintenance-free micro gas turbine generators (30-100[kW] class) are expected in it. In this study, the author conducts research and development of self-acting gas bearing, in which a multilayered foil bearing is roposal.
