Abstract
A method for correcting the radial moment weight of a vane, includes the step of providing a vane extending along an axis of elongation (Z) between a free end and an opposite root, the vane having a blade made of composite material and having a leading edge. The method further includes the steps of measuring the radial moment weight of the vane and comparing the measured radial moment weight to a reference value and adjusting the radial moment weight of the vane according to the result of the comparison. The vane has at least one adjustment cavity extending along the leading edge and opening into the free end of the vane. The adjustment is carried out by inserting a first material into the adjustment cavity.
