The simple method is based an a solidity to be specified and on relative flow angles at leading and trailing edge 1 and β2). These angles will be estimated in the automatic mode or on request (by pressing calculate) based on zero incidence and deviation as well as on the Euler equation (β2). The geometric profile parameters stagger angle γ and chord length l will be determined by:

γ = 0.5 (β1 + β2),

l = l/t * π·d/z.
