Zero running clearance centrifugal compressor
A turbine engine includes an engine housing enclosing: a centrifugal compressor having a rotor; at least one centrifugal compressor bore mounted to the rotor; at least one blade mounted to each of the at least one centrifugal bore and disposed proximate to at least one static wall; a turbine disposed in connection with the centrifugal compressor; a thrust bearing disposed in connection with the rotor; and means for moving said rotor with reference to the at least one static wall attached to the thrust bearing.
1. A turbine engine, comprising:
an engine housing enclosing:
a centrifugal compressor including:
a rotor;
at least one centrifugal compressor bore mounted to said rotor;
at least one blade mounted to each of said at least one centrifugal bore and disposed proximate to at least one static wall;
a turbine disposed in connection with said centrifugal compressor;
an innermost static wall;
a seal disposed between and in contact with the innermost static wall and said at least one static wall for allowing thermal expansion and axial movement of the innermost static wall with respect to the at least one static wall;
a thrust bearing disposed in connection with said rotor; and
means for moving said rotor with reference to said at least one static wall attached to said thrust bearing, said means for moving said rotor comprising a first gear attached to a bearing mount, a second gear for engaging the first gear, and means for driving the second gear.
