The formula for calculating the change in lift (ΔL) produced by slats on an aircraft depends on various factors, including the angle of deflection (θ), the air density (ρ), the reference area (S) of the wing, the coefficient of lift (Cl) of the wing without slats, and the slat effectiveness factor (K).
- ΔL represents the change in lift due to the deployment of slats.
- ρ is the air density.
- S is the reference wing area.
- Cl is the coefficient of lift of the wing without slats.
- θ is the angle of deflection of the slats.
- K is the slat effectiveness factor, which accounts for how effective the slats are at changing the lift.
