Abstract

An experimental investigation is carried out to reveal ultimate load-carrying capability for leaf-type axial air foil bearings intended for low-sized high-speed turbo-machines. A new nondestructive technique is suggested to estimate this characteristic essentially simplifying experimental work. A test rig is described, which is aimed to evaluate ultimate load-carrying capability for axial air foil bearings. Some test results are presented for axial air foil bearing with 37 mm outer diameter and maximum rotation per minute up to 90000.
