Airflow and spools
Follow the core airflow from intake to exhaust, then trace the separate mechanical path that returns turbine work through the concentric shafts. The airflow and torque relationships are typed separately so they cannot be mistaken for one another.
Reviewed low-pressure system
The first reviewed concept set covers the fan, low-pressure compressor, low-pressure shaft, and low-pressure turbine, with direct links into approved ATPL practice questions.
