Abstract: The complex mechanical gear trains and lubrication systems of conventional engine configurations are eliminated by using combinations of hydrodynamic air foil bearings, hydrodynamic solid geometry carbon seals/bearings, magnetic bearings, and electrical starter/generators that can also act as bearings to support the high speed shafts of gas turbine engines. The various bearing types and the starter/generators are arranged in such a way as to share peak loads experienced by the engine shaft during maximum aircraft maneuvers. This results in a minimal bearing and engine size.

Abstract: A ceramic finger seal for use between a housing and a combustor liner to inhibit air passage therebetween and for use in fluid sealing between a rotating shaft and a housing circumscribing the rotating shaft. The ceramic finger seal has at least two annular diaphragm members constructed of two or more diaphragm segments bonded end to end by ceramic cement or other high temperature joining compounds. The diaphragm members may be partitioned into a generally continuous inner diameter portion and a segmented outer diameter portion or the reverse thereof. The segmented portion includes finger elements spaced uniformly apart forming gaps therebetween and extend radially outward or inward terminating in a foot portion. The rolled edge on the finger is formed by laser cutting to prevent gouging of the combustor liner surface.
