摘要： A method for monitoring the torsion of a rotary shaft on an aircraft turbomachine based on the measurements from at least three sensors distributed along the rotary shaft to divide the shaft into at least two shaft segments, the method comprising: a step of measuring, for each sensor, a parameter dependent on the rotation of the shaft, a step of calculating, for each achievable pair of sensors, a parameter related to the torsion of the shaft, a step of comparing the different calculated parameters related to the torsion of the shaft with references, a step of detecting damage on a shaft segment at the end of the comparison step, and a step of indicating the localization of the damage on the shaft from the shaft segment for which damage has been detected.

摘要： A platform for a fan of a turbomachine that will be mounted on a hub of the fan between two adjacent blades, the platform comprising a principal wall with a longitudinal principal orientation, that has a curved shape along the longitudinal direction, and a stiffener that is mounted on a lower face of the principal wall, of which the section of the stiffener, in a plane perpendicular to the longitudinal direction is globally in the form of a U open towards the principal wall. The stiffener comprises at least two straight segments inclined relative to each other and inclined relative to the longitudinal principal direction.
