Application of Gas Foil Bearings in China

Gas foil bearing has been widely used in high-speed turbo machinery due to its oil-free, wide temperature range, low cost, high adaptability, stability and environmental friendliness. In this paper, state-of-the-art investigations of gas bearings are reviewed, mainly on the development China. After decades development, progress achieved field Small-scale applications have realized a variety machinery. The prospects markets very broad. Various turbomachines with developed. Due different application occasions, higher reliability requirements imposed technology. Therefore, design principle, theory, manufacturing technology should be adaptive new occasions before mass production. Thus, there still number inherent challenges that must addressed, for example, thermal management, rotor-dynamic wear-resistant coatings.
