METHOD FOR MANUFACTURING A TURBOMACHINE FAN HAVING A REDUCED NOISE LEVEL AT MULTIPLE ROTATIONAL FREQUENCIES OF SAID TURBOMACHINE

摘要

The invention relates to a method (100) for manufacturing a turbomachine fan comprising a plurality of blades mounted on a disc extending along a longitudinal axis, said method comprising the following steps of: - measuring (102) at least one structural parameter of each of the blades in the cold state, and, for each of the blades, estimating (103) at least one structural parameter in operation relating to a blade from the structural parameter(s) measured on said blade in the cold state, - determining (104) an optimal sequence of the blades around the disc from the structural parameters estimated in operation for each of the blades, and - mounting (105) the blades on the disc in the optimal sequence thus determined.
