1. A thermal control module of a gas generation system comprising:

  • a turbine wheel connected to a pressurized air supply such that the pressurized air from said pressurized air supply rotates the turbine wheel and said pressurized air becomes cooled air;

    a regenerative heat exchanger receiving cooled air from said turbine wheel, receiving pressurized air from said pressurized air supply, cooling said pressurized air to generate cooled air and generating exhaust air;

    a compressor rotated by said turbine wheel, receiving the cooled air from said regenerative heat exchanger and generating compressed air; and

    an ejector connected to said regenerative heat exchanger providing said exhaust air into ram air flow;

    wherein the pressure ratio across the turbine wheel remains stable relative to altitude changes.
