A fan blade automatic modelling and design technique is proposed. Starting from axial flow fan nominal head H, flow rate Q and revolution speed ω, a numerical constrained optimization procedure is proposed. Fluid-dynamic, as well as geometrical, structural and vibration constraints are taken into account in the evaluation of the optimal objective function. Details of the numerical implementation, as well as results concerning a real application example, are reported and discussed.
