Advanced Integrated NDT concepts for unified Life-Cycle

Record Control Number : 30642
Quality Validation Date : 2003-05-13
Update Date : 2003-10-15
Abstract : 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.
