Abstract
A gas turbine engine has a fan driven by a fan drive turbine through a gear reduction, a low pressure compressor and a high pressure compressor. The high pressure compressor is driven by a high pressure turbine and the low pressure compressor is driven by a low pressure compressor drive turbine through a mechanical transmission that increases the speed of the low pressure compressor relative to the low pressure compressor drive turbine. A tap taps air from the low pressure compressor and delivers the tapped air as cooling air to the high pressure turbine.
