In a single-spool engine, the high-pressure turbine drives the entire compressor. In a dual-spool engine, the compressor and high-pressure turbine are both split into two segments.
Difference between Two Spool Engines and Three Spool Engines
A two-spool engine has two concentric shafts that rotate at different speeds: one connects the high-pressure turbine stages to the high-pressure compressor, and the other connects the low …
