The project is led by the 3 main aerospace industries present in Wallonia: Sonaca, Sabca and Techspace Aero. It aims at developing composite structures for various aeronautics applications. CSL leads the non-destructive inspection task, benchmarking different emerging non-contact techniques for aeronautics, such as shearography, thermography and ultrasonic laser. During the related timeframe, CSL carried out the benchmark for the three selected techniques and identified the ultrasonic lasers as the most innovative and promising. By 2013, CSL designed a specific robotic test bench in order to assess the ultrasonic laser control capabilities.
Full-Field Advanced Non Destructive Testing Technique for Online Thermo-Mechanical Measurement on Aeronautical Structures (2009-2012) Funded by European Union - FP7. CSL coordinates the FANTOM project, with a total of 6 partners. The FANTOM project aims at developing an innovative non destructive testing based on association of thermography and holographic techniques, using lasers in the thermal infrared spectrum (around 10 μm). The applications are mainly the thermomechanical behaviour assessment of aeronautical composite structures but also the flaw detection in such structures. The project has proven so far that it was possible to combine holography and thermography in a single sensor. A transportable set-up is currently under investigation for various non destructive testing applications. Tests are scheduled at Airbus premices in 2012.
In the frame of the Guide2Dye project we developed a new design concept for solar concentration based on wave guiding and spectral splitting of light. Planar solar concentrators allow guiding incident light onto spatially separated solar cells. Our idea consists in spectrally assign parts of the incoming flux to solar cells with suited spectral responses. By comparison with MJ cells, it has the advantage of enabling the independent control of output power of each junction.
The goal of the project is to develop a novel digital holographic technique targeted at space reflector deformation measurement. It consists of a long wave infrared (LWIR) digital holographic interferometer (DHI) to measure relatively large displacements, typically 250 µm, of complex surfaces, shapes and structures under both ambient and thermal vacuum condition with a measurement uncertainty of 0.25 µm. This LWIR digital holographic interferometer provides a new measurement technique to fill the gap between holography/interferometry in the visible and techniques based on structured light illumination.
This project is led by OPEN ENGINEERING and aims to develop new CAE tools that integrate in a coupled way methods and simulation in different field: aerodynamic, thermal, structural, optical, electrical and acoustical fields. CAE is presently used in all the industries for analysis and prediction of their own products. The goal of these simulations techniques are :
Reduction of the optimization time (time to market)
Increase the liability of the predicted models
Use of design optimization methods on parametric model to increase the performances.
Due to the increase power capacities of the computer, there is a demand from the industry to produce simulations as close as possible from the reality.
First France-Belgium consortium on this subject, PLASMOBIO is a multidisciplinary project grouping biologists, physico-chemists, physicists and micro-technology experts, investigating several scientific issues. To facilitate an efficient valorization of the project results and communication, Eurasanté (economic development agency) was also be part of the consortium. Chemistry and topography of sensing surfaces play a major role in SPR instruments performance. Therefore, one of the objectives of PLASMOBIO was to improve surfaces characterization and functionalization. Using micro-structures, micro-patterning techniques, localized SPR (LSPR), this research project aimed to create new plasmonic sensitive interfaces adapted to clinical applications. Optical Integrated Circuits in SPR systems are investigated to create particular sensing arrangements and therefore enhance analysis performances. This project also proposes to design new microcantilever-based biosensors which can assay analytes in low concentrations. By combining these technologies, PLASMOBIO allowed to create fully integrated SPR-based biosensors dedicated to medical applications
Radiation shielding of composite space enclosures
Composite structures show potential for significant mass savings. Composite constructions can meet the structural and thermal constraints set for the traditional aluminum spacecraft electronics housings. However, radiation protection capabilities of composite structures provide considerable challenges. Energetic particles, mainly electrons and protons, can destroy or cause malfunctions in spacecraft electronics. Therefore, adequate protection for the electronics has to be provided by the electronics housing together with local shields. Space electronic systems employ enclosures to shield sensitive components from space radiation. The purpose of shielding is to attenuate the energy and the flux of ionizing radiation as they pass through the shield material, such that the energy per unit mass (or dose) absorbed in silicon is sufficiently below the maximum dose ratings of electronic components. The standard practice in space hardware is the use of aluminum as both a radiation shield and structural enclosure. In SIDER project, a technology based on nanomaterial is proposed as an alternative for the radiation shielding. A second strategy based in the incorporation of a high density material foil is also being considered. The adhesion of the foil to the CFRP laminate is an issue to be solved.
