Abstract

A fluid-film foil bearing has a resilient bearing insert assembly disposed between a rotatable and a stationary member. The insert assembly comprises a plurality of resilient corrugated spring pad supports separated from each other to provide a series of spaces and a compliant, unitary foil mounted on the pad supports, the foil having a plurality of perforations aligned across its entire width and over the spaces which are operative under dynamic conditions both to initiate foil deflection and to cause uniform replenishment of fluid lost through side leakage.
