The Development of High speed Gas Bearings for Aviation turbo-refrigerator

Some high Speed gas bearings for aviation turbo-refrigerator with high performance parameters were introduced. Concerning the necessity, feasibility and specificity of substituting roller bearings with gas bearings on turbo-refrigerator which work under severe conditions,some special tests and research work in the course of developing gas bearings (such as, gas bearing design,material selection ,manufacture and adjustment),aviation environment adaptable tests and application of the turbo-refrigerator retrof-fited with gas bearings were described.
