OPTIMIZATION OF THE SUPPORTING SURFACES BEARING USING PRESSURIZED AIR
In perspective multi-mode aircraft will use the combined direct-flow turbo and turbo-rocket engines. Application of the technology of air bearings will significantly improve the life of the important parts, like compressors and turbo pump assemblies. At this point in the world in the aerospace engineering the most common gas-dynamic bearings, not bearing with pressurized air. Gas-dynamic bearings are characterized by the backing of various designs, which provides performance rotors for starting and stopping. The main problem of this type of bearing, in addition to the complexity of design, is the limited durability of the backing layer. Bearing using pressurized air has no such defect, since physical contact between solid surfaces are missing. This article consists calculation results of the supporting surfaces bearing using pressurized air. The dependences of the main parameters of the configuration supporting surfaces of the shaft are considered as well as aerodynamic resistance of pads for different modes of operation.
