WebThe wing chord distribution, or planform, is partially given by equation (1). This now becomes c(y)cℓ(y) = 2Γ0 V ∞ s 1− 2y b 2 which states only that the c × cℓ product must be elliptic. How c or cℓ vary individually is not determined, but rather must be chosen by the designer. The possibilities are unlimited, WebMar 12, 2024 · The airfoil shape is non dimensional, but real blades have a specific size, or chord length, at each location along their length. E.g. the airfoil at 10’ radius will have a 1.1’ chord. This chord distribution or taper must be selected to provide enough thrust at the design rotor speed.
