Abstract: A profile for a trailing edge of an airfoil, the trailing edge including flanges, and the profile is U or V shaped, is made of composite material and includes: sections joined at a first profile end and defining an inner space, and recesses arranged along the two sections towards the inner space and complementary to each other between the two sections; wherein the profile is configured to follow a theoretical aerodynamic contour of the airfoil so that the two sections partially cover the trailing edge and the flanges are housed inside the inner space, and wherein each of the plurality of recesses defines at least two joining points through which the two flange of the trailing edge and the two sections are configured to be joined each other.
