Turbomachine blades checking method, involves calculating aerodynamic parameter of blade section, and validating blade if value of aerodynamic parameter falls within validity range or rejecting blade if value lies outside validity range

摘要

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.
