Vortex generators on the fenders help control turbulent airflow, enhancing the stability of 86.
Those little fins —
the vortex generators on the upper side of the airfoil — create vortices to enhance lift at takeoff and landing.
Not exact matches
Vortex generators operate
on a basic aerodynamics principle — that if you reduce the separation of the airflow
on the leeward side of an airfoil, you can enhance the lift and at the same time reduce the drag.
That party piece, now thinner, works in conjunction with
vortex generator strakes
on the trailing edge of the roof line, which are sandwiched by two raised «horns».
