AI Technical Summary

Technical Problem

Current methods for monitoring materials in turbomachine component production lack real-time prediction capabilities, as hyperspectral measurement data in its unprocessed form does not provide sufficient conclusions about material quality, leading to potential component failures and increased production costs.

Method used

A method involving a hyperspectral camera system that sequentially measures powdered material, using AI-based evaluation to predict metallographic and mechanical properties, allowing for real-time assessment of material suitability and operational reliability, and integrating spectral, angular, and time information to detect deviations such as contamination or particle size issues.

Benefits of technology

This approach enhances the operational reliability of turbomachine components by reducing scrap during production, optimizing the production process, and ensuring component quality through continuous material testing, thereby reducing time and costs.

Abstract

The present invention relates to a method for testing a material for producing a component for a turbomachine, in particular an aircraft engine, comprising the following steps: i) providing the material in powder form; ii) sequentially measuring in each case a portion of the pulverulent material using a hyperspectral camera system; iii) determining the suitability of the pulverulent material for the production of the component based on the measurement results ascertained in step ii).
