Abstract: Transition of composite laminates for a modular blade. The real load distribution per element F2 is flattener, overlapping with the theoretical load distribution per element F2theor by a non-homogeneous hybrid laminate across the width of the same, with an area at the ends having a very high modulus of elasticity E2′ext and an area in the centre having a lower modulus of elasticity E2′int. Furthermore, the transition has a variable length with respect to the width of the cap, to the width of the joint and to the angle of optimal design for transferring the lead α, all according to the formula Ltransition=0.5(Wjoint−Wcap)tan−1(α).
