A microturbine engine core with gas bearings used to support a rotating group is provided, including methods of optimizing the engine core's performance. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to ascertain quickly the subject matter of the technical disclosure. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.


1. A method for cooling and for optimizing the operating pressure of gas bearings used to support a rotating group that includes a shaft and a compressor, the method comprising the steps of:(a) supplying a portion of compressed air from the compressor to a cooling circuit, thereby creating an air flow in the cooling circuit; (b) splitting the air flow in the cooling circuit, thereby creating at least a first separate flow path and a second separate flow path in the cooling circuit; (c) flowing the air in the first separate flow path through at least one ...
