Abstract
A gas turbine which is capable of operating in more than one pressure mode. The gas turbine, which may include a single fixed spool, multiple fixed spools, or a combination of fixed spool(s) and a free turbine, can operate in a positive pressure mode, a transatmospheric mode, or a subatmospheric mode. Valving is provided to control the particular pressure mode of operation in response to system requirements and to switch between pressure modes as required.
