15. Gas turbine engine

A free turbine is

  • not directly connected to the power output shaft.
  • connected directly to the propeller and compressor.
  • connected directly to the power output shaft.

Explanation from PART66Online

A free turbine is not mechanically linked to the gas-generator/compressor spool; instead it is connected to the power output shaft, extracting energy from the gas stream to drive the propeller or load. This independence lets the output shaft turn at a speed unrelated to the gas-generator speed.
