Abstract
A field deployable, portable structured light measurement (SLM) apparatus, together with a structured light measurement process to manage part to part variation in production and in the field, to support both rotor airfoil mistuning and rotor airfoil repair limits.
Claims7
A method of assessing a component of a gas turbine engine while disposed on the gas turbine engine using a field deployable, portable structured light measuring apparatus including at least a portable base structure and an articulating arm member, the method comprising the steps of:
- deploying the field deployable, portable structured light measuring apparatus relative to a gas turbine engine containing the component, the component including at least one of an airfoil of a compressor rotor or blisk fan of the gas turbine engine to be assessed while the gas turbine engine is disposed within its field of use installed on an aircraft;
- using the field deployable, portable structured light measuring apparatus to generate structured light measurement data of the airfoil;
- generating a model of an entire operational portion of the airfoil using the structured light measurement data representative of at least one operational characteristic data of the airfoil at least including a natural frequency of the airfoil;
- and
- assessing a condition of the airfoil based upon the airfoil operational characteristic data and at least one comparison data.
