Abstract (en)
[origin: EP1749969A1] The method involves measuring geometrical coordinates of multiple points located on the profile of a blade section (10) of a turbomachine. An aerodynamic parameter of the blade section is calculated based on the measured coordinates. A blade is validated if the value of the aerodynamic parameter falls within a validity range or the blade is rejected if the value lies outside the validity range. The validity range is defined by a value of a nominal aerodynamic parameter of a reference blade and associated tolerance of the nominal parameter. Independent claims are also included for the following: (1) a computer program directly loadable in a memory of a computer for implementing a turbomachine blades checking method (2) a turbomachine blades checking system.
