dual-spool gas turbine engine dual-spool gas turbine engineAn axial-flow turbine engine with two independent axial-flow compressors, each driven by its own stage(s) of turbines. The high-pressure, or N2, compressor is speed governed by the fuel control system. The speed of the low-pressure compressor, or N1, is not governed; it seeks its own speed as the ambient air density changes. See dual compressor. |
