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 .
