ABSTRACT:
A gas turbine engine cooling airflow pickup and delivery system which radially inwardly traverses the torque transmittal path of the compressor section at a relatively large radius location, then extends substantially farther inwardly to a significantly smaller radius location, all with minimal static pressure loss to the cooling airflow. Pressurized, substantially non-swirling air from the compressor stage is supplied to a collector, and from the collector thru pickup holes arranged at an angle of 45 degrees reversely to the direction of rotation of the shaft. The pressurized air is then lead into a vortex spoiler which has a plurality of blades smoothly curved reversely to the direction of rotation of the shaft, the radially outer end of each blade being inclined in matching relation to the pickup holes.
