摘要： A method of checking turbomachine blades is presented that may be implemented using a computer and a measuring device. Turbomachine blades compatible with embodiments of the method have a profile including a centerline, suction face, pressure face, leading edge and trailing edge. The method measures geometrical coordinates of many points on a blade section profile, calculates an aerodynamic parameter of the blade section as a function of the measured coordinates, verifies whether the calculated aerodynamic parameter value departs from a valid range of parameters from a reference blade, and validates or rejects the blade depending upon whether the value of the aerodynamic parameter falls within the valid range.

摘要： 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.
