Module 11A Aeroplane Turbine Practice Questions - UK CAA Part-66 AME Module 11A - Turbine Aeroplane Aerodynamics, Structures And Systems Exam

Why are vortex generators fitted to the upper surface of swept wings on turbine aeroplanes?

To re-energise the boundary layer with high-energy air from above, delaying shock-induced boundary layer separation To increase laminar airflow across the entire wing root area To reduce wingtip vortices and decrease induced drag during cruise To generate aerodynamic lift directly at low angles of attack

Correct Answer:

To re-energise the boundary layer with high-energy air from above, delaying shock-induced boundary layer separation
