Abstract: The present invention relates to the checking of turbomachine blades having a profile comprising a centerline, a suction face, a pressure face, a leading edge and a trailing edge, consisting in: measuring geometrical coordinates of a plurality of points located on the profile of at least one blade section; calculating at least one aerodynamic parameter of the blade section as a function of the measured coordinates; verifying whether the value of the calculated aerodynamic parameter departs from a validity range defined by a value of the nominal aerodynamic parameter of a reference blade and an associated tolerance; and validating the blade if the value of the aerodynamic parameter falls within the validity range or rejecting the blade if the value of the aerodynamic parameter lies outside the validity range. The present invention also relates to a computer program, which can be loaded directly into the memory of a computer, intended to implement the method according to the invention.

Abstract: A device for controlling variable-pitch vanes in a turbomachine comprises links connecting the radial pivots of the vanes to radial fingers carried by semicircular elements and bridges of a control ring, the links being mounted in ball-and-socket manner on the radial fingers which are fixed to the control ring. This form of mounting enables all the vanes associated with the control ring to be set to the same angular pitch.
