What is the main purpose of a frise aileron?
- Increase drag on the up going aileron.
- Decrease drag on the up going wing surface.
- Help the pilot overcome aerodynamic hinge loads.
Explanation from PART66Online
A Frise aileron is hinged so that when it deflects up its leading edge protrudes into the airflow beneath the wing, increasing drag on the up-going aileron (the rising-wing side). This added drag balances the higher induced drag on the descending wing, reducing the adverse yaw that would otherwise oppose the turn.
