| 1. A gas turbine engine system, comprising:
a compressor section;
the compressor section comprising a first compressor stage and a second compressor stage;
a turbine section;
the turbine section comprising a first turbine stage and a second turbine stage;
one or more pressure sensors located within the turbine section;
a first flow path connecting the first compressor stage and the first turbine stage;
a second flow path connecting the second compressor stage and the second turbine stage;
a crossover flow path connecting the first flow path and the second flow path; and
an ejector positioned about the crossover flow path and the first flow path;
the ejector comprising a mechanically variable motive nozzle ejector with a movable ram positioned therein operable by an
actuator in communication with the one or more pressure sensors;
wherein the actuator varies the position of the movable ram based upon a sensed pressure.
