spool
/spuːl/
noun5
- One of the rotating assemblies of a gas turbine engine, composed of one or more turbine stages, a shaft, and one or more compressor or fan stages.
- The high-pressure spool rotates faster than the intermediate- and low-pressure spools, as the high-pressure turbine is driven by superheated combustion gases straight out of the burners, while the high-pressure compressor has to spin very fast to compress air that has already been compressed and heated by the low- and intermediate-pressure compressors.
