The formula for calculating the effectiveness of wing slotted flaps can vary depending on factors such as the specific design of the flap, the aircraft’s characteristics, and aerodynamic principles. Generally, engineers use complex equations and computational fluid dynamics (CFD) simulations to determine the performance of wing slotted flaps.
Where:
- = Incremental lift coefficient due to the flaps
- = Flap area
- = Total wing area
- = Maximum lift coefficient increment due to the flaps
- = Maximum deflection angle of the flaps
