A cooling airflow compressor system and methods for reducing a cooling airflow is described. The cooling airflow compressor system utilizes a primary high pressure compressor in combination with a secondary high pressure compressor to further compress a primary airflow. The secondary high pressure compressor includes a rotor driven by a high pressure turbine connected by a high pressure turbine shaft to the primary high pressure compressor. A heat exchanger is connected to the secondary high pressure compressor to further cool the cooling airflow. The cooling airflow is utilized to cool the turbine and a high pressure turbine vane.
