Deliverables
The innovative step required within this Project, was to establish an effectual link between the NDT field and the other engineering disciplines used during the aircraft life cycle. To achieve this goal, the main industrial objectives were as follows:
-To standardise the NDT workshop architecture and to provide software tools aimed at:
-Improving communication and data exchange between NDT and other engineering disciplines working within the life cycle;
-Supporting the preparation of the inspection procedures, reducing the experimental work and contributing to increase the reliability and optimisation of the inspections;
-Allowing the design of appropriate transducers for a wide variety of specific applications;
-Expanding the exploitation of the NDT technologies, sustaining their application as characterisation methods for materials, structures and defects;
-Developing advanced non-destructive techniques and/or analysis methodologies;
-Enabling the detection and quantitative analysis of anomalies presently subjected to destructive evaluations to address repair intervention;
-Introducing fast non-contact inspections;
-Linking the results from different inspection techniques, which have been applied to the same structure thus solving doubtful inspection results and therefore reducing the amount of scrap on what could potentially be �acceptable� parts.
-To increase EU competitiveness, both from a technological and economical point of view, through the following achievements:
-More powerful model-based NDT techniques;
-Coupling of NDE data to CAD files for more efficient diagnosis;
-Availability of new powerful software tools for automatic defect recognition and classification;
-Availability of a set of tools which allow designers and manufacturing engineering specialist access to NDT information in terms of inspectability of parts;
-New tools for aircraft maintenance based on the possibility to compare production and in-service inspections data;
-Validation of the NDT methods performance by combining data coming from real and virtual defects;
-Developing NRT inspection techniques for corrosion detection and characterisation;
-Air-coupled US techniques for the measurement of viscoleastic properties;
-Optimised probes and signal processing algorithms for pulsed eddy current inspections;
-Optimised test coils and inspection parameters for electromagnetic techniques;
-Moiré based prototypical system for external defect detection and monitoring.
The detailed objectives are summarised in the following. After the assessment of the state-of-the-art and the definition of the industrial requirements, modelling and technique developments have been carried out. Finally, the outputs of modelling and technique developments have constituted the inputs for the integration activities.
The objectives for the modelling activities were the development of:
-The simulation of the physics of the ultrasonic inspections (testing media, test object characteristics, test geometry) applied to the investigation of composite structures (bulk waves). The aim is to predict amplitude and pulse shape of signals detected in a hypothetical scan over a defined component. Moreover, the models shall be adaptable for changes in probes, scanning patterns and/or data recording procedures.
-A model of automated visual Shape from Shading techniques, enabling reliable non-contact, full field inspections on metallic structures and furnishing software tools to characterise surface flaws
-Models of thermographic techniques applied to composite structures, with the aim to predict the detectability of particular defect/material configuration thus reducing practical experimentation.
-The simulation of electromagnetic NDT to replicate the physics of the testing media, the characteristics of the test object, and the geometry of the test.
