Guided journey

Core airflow: intake to exhaust

Follow the working fluid through the generic two-spool turbofan before tracing the shafts that return turbine work to the compressors and fan.

Comparison

Compare where each high-lift device sits and how it changes the wing.

Compare	Trailing-edge flap	Leading-edge slat
Location	Inboard trailing edge	Wing leading edge
Primary effect	Increases camber and often area	Opens a slot that delays separation
Exam distinction	Adds substantial lift and drag	Helps sustain attached flow at high angle of attack

Low-pressure turbine

The low-pressure turbine extracts work from the core gas stream to power the low-pressure shaft, fan and booster.

Where it is: Downstream of the high-pressure turbine and upstream of the exhaust in the core.
What it does: It supplies the mechanical work required by the low-pressure spool.
Relationship: Its torque travels forward through the low-pressure shaft to the fan and low-pressure compressor.
Common confusion: A turbine extracts work from gas. It does not directly push the aircraft forward through its shaft.

Check yourself

Without looking back, can you explain where the low-pressure turbine is, what it does, and which component drives it or is driven by it?

Scope: Generic two-spool high-bypass turbofan teaching model. Reviewed 2026-09-09.
