Exploitable results
Aeronews' overall result was to provide an enhanced, reliable and integrated prototype measurement system and protocol for microcrack diagnostics of selected aircraft components and structures, through the development and preliminary verification of an innovative NEWS-based non-destructive testing (NDT) technology and its engineering applications in aeronautics. Several intermediate results were used:
Aeronews identified and selected critical parts and structures of interest to aeronautics NDT and on identifying several of the most common failure scenarios. This work led to an extensive database of available testing material. In so doing, Aeronews also built an extensive database on the type of damage (failure scenarios), from weak bonding to single cracks, localised and extended micro-cracked regions, and corrosion.
Aeronews developed diagnosis techniques, including non-linear wave propagation, non-linear wave modulation, impact modulation, and non-linear reverberation spectroscopy. The results were promising, showing both global and local signatures of damage. To prove the increased sensitivity of non-linear techniques in NDT evaluations, an extensive monitoring experiment was planned and executed on a field test site. Moreover, the experience gained using the NEWS techniques allowed for the setting up of a database of the most important characteristics, requirements and limitations of the various techniques.
Aeronews provided numerical support for the experiments, and developed, through intensive NEWS modelling, two methodologies for a NEWS technology-based imaging system: Newimage and 'Multi Mode Non-linear resonance acoustic spectroscopy (Mumonras). The main conclusion from this third result is that numerical simulations have indeed supported the developments on the experimental level for NEWS-based imaging techniques of micro-damage.
Concerning the design of smart transducer/sensing systems, Aeronews conducted a survey on current and emerging sensor and transducer technologies and a mapping of these technologies to the specific demands of NEWS and Newimage. The conclusion of this study made clear that no single transducer/sensor would be the answer for all techniques since the techniques themselves are different in nature and have different requirements.
The project developed prototypes for transducer/sensing systems, including specific hardware design (ceramic elements, cheap optical/piezoelectric transducers, smart surface contact transducers and systems, etc.).
Finally, the consortium analysed and studied wireless airport communication systems, in order to investigate the development of a microcontroller-based integrated system that would provide hand-held monitoring and display of the data provided by the sensors.
Technical implications of results by theme
The conclusion of the 'experimental week', in which the field tests were carried out, was that, although the various techniques were not yet optimised for the use on extended and complex samples, results were overall positive and provided useful guidance as to how the technique can be improved.
Due to the increased sensitivity of the technology, it is expected that this development will result in a significant increase in aircraft and passenger safety while contributing to substantial cost savings through a decrease in maintenance and operating times. The long-term goals are the engineering of a standard measurement system based on NEWS for continuous health monitoring and early-stage damage diagnosis.
However, all developments (software and hardware) carried out under the Aeronews framework and successfully tested will finally lead to commercial exploitation. Therefore, Aeronews developments fully comply with current standards and regulations, with the aim of being installed in airborne systems.
