20 Claims

1. A method of manufacturing a turbomachine including a collector, a frame, and a compressor having an impeller and adjustable shrouds, the impeller having a plurality of impeller blades, the method comprising:

providing mechanical and thermal attenuation between the collector, compressor, and frame by independently supporting the collector and compressor by the frame, to minimize, during operation, the transfer of mechanical and thermal energy between the collector and compressor,

incorporating at least one impeller bypass flow path for the direct transfer of air between ambient and a location in the collector downstream of the impeller blades; and

providing the at least one impeller bypass flow path between the collector and the adjustable shrouds.
