A gas turbine engine includes a fan, a fan drive gear system coupled to drive the fan about an engine central axis, a compressor section including a first compressor and a second compressor and a turbine section. The turbine section includes a first turbine coupled to drive a first spool. The first spool is coupled at a first axial position to a compressor hub that is coupled to drive the first compressor. The first spool is also coupled at a second, different axial position to a fan drive input shaft that is coupled to drive the fan drive gear system. The turbine section also includes a second turbine coupled through a second spool to drive the second compressor. A sensor probe is operable to determine a rotational speed of the first spool. The sensor probe is located at a third axial position that is axially forward of the first axial position and axially aft of the second axial position.
A gas turbine engine comprising:
A method of assembling a gas turbine engine, the gas turbine engine including a first turbine coupled to drive a first spool, the first spool being coupled at a first axial position to a compressor hub that is coupled to drive a first compressor and the first spool being coupled at a second, different axial position to a fan drive input shaft that is coupled to drive a fan drive gear system that drives a fan, the method comprising:
