Typical flaps/slats extension chord ratios?

Fowler flaps for example extend the chord of the airfoil by about 25%. So their chord ratio is C'/C = 1.25. Does anyone know similar values for other types of flaps, like double/triple slotted Fowler ...

Comparison between Split and Slotted Flaps

Question 4: As we know, the more complicated design of high lift systems, gives us more maximum lift @ takeoff, such as slotted (single - double) or fowler flaps type. Beside the point of view of ...

Is pitch-flap coupling an aerodynamic effect or an intrinsic property of a delta 3 offset?

I am modelling a propeller, in particularly the equations of motion of the various pitch/lag/flap angles as the propeller is turning around. The blade includes a $\delta_3$ angle, which provides pitch-...

I have a wing with an airfoil s1223 which is an airfoil with a lot of camber. the take off distance is limited so I want to implement flaps for this issue but I have the doubt if this is a good idea.
