In aircraft design, spoilers are aerodynamic control surfaces used to reduce lift and increase drag on an aircraft. They are typically located on the wings and can be raised or extended into the airflow to disrupt the smooth flow of air over the wing. Spoilers serve various purposes, including assisting in controlling the aircraft’s descent rate during landing and providing roll control
- ΔL represents the change in lift.
- ρ is the air density.S is the reference wing area.
- Cl is the coefficient of lift (without spoilers).
- Cd is the coefficient of drag (without spoilers).
- θ is the angle of deflection of the spoilers.
- K is the spoiler effectiveness factor, which accounts for how effective the spoilers are at changing the lift or drag.
