Delft University of Technology, founded in 1842, is the oldest, largest and most comprehensive university of technology in The Netherlands. It offers a wide variety of education in Science, Engineering and Design. A total of 19.000 students are enrolled in one of its 16 bachelor programs or in one of its 40 master programs including several Erasmus Mundus Masters. TU Delft has shown its responsibility towards society by focusing its research on four global themes: Energy, Environment, Infrastructures, and Health. It is a partner in two recently granted KIC’s (Knowledge and Innovation Community) Environment and ICT.

Delft University of Technology, also known as TU Delft, is the largest and oldest Dutch public technological university, located in Delft, Netherlands

The Faculty of Aerospace Engineering is a well-established Aerospace School and one of the largest in the world. It was founded in 1940 and currently has about 300 staff members and a student body of 2300. Furthermore, its unique technical infrastructure includes a flying test bed (Cessna Aircraft, jointly owned and operated with the NLR), numerous research wind tunnels and laboratories equipped with sophisticated non-intrusive measurement techniques. The Faculty is an internationally oriented organisation and participates in a large number of international networks, the European Consortium for Advanced Training in Aerospace (ECATA), and the International Council for Aeronautical Sciences (ICAS).

The Structural Integrity & Composites Group has over the past decades developed the FML concept for structural integrity and damage tolerance towards the application on the Airbus A380. Together with that, the group develops methods to predict the strength, fatigue and damage tolerance performance of metallic, hybrid and recently also composite structures.

The Aerospace Non-Destructive Testing (AeroNDT) Laboratory at TU Delft is the centre for ultrasonic and optical measurements. Our research is in measurement technology, algorithms for characterisation of materials & structures. Our vision is to develop the next generation of advanced optical & ultrasonic sensors and sensor systems which can measure more accurately, faster & with better resolution. The AeroNDT Laboratory has equipment and expertise in shearography, holography, 3D shape measurement, optical coherence tomography, fibre optic sensors, wireless and energy harvesting sensors for SHM, hyperspectral imaging, terahertz imaging, C-scan, phased array and air-coupled ultrasound and active and passive Lamb wave techniques.

The AeroNDT Laboratory is leading WP6 of the EXTREME project with research and development of new in-situ and post-impact damage characterisation SHM/NDT techniques. A new high-speed 2D optical strain measurement techniques and various embedded sensors (including optical fibre based) will be used for sensing during extreme dynamic events. The experimental results will be used for verification of the numerical models developed within the EXTRME project. New techniques for post-impact damage characterisation will be developed to support design and in-service inspection of aerostructures.

Within the EXTREME project the AeroNDT Laboratory is developing:
Advanced shearography instrument to provide accurate 3D strain measurement of composites, exceeding the state of the art capability of commercial strain measurement systems. High speed measurements at microseconds time scale will be done during the impact event using a pulsed laser.

THz imaging system for post-impact damage characterisation with sub-millimetre spatial resolution which will be used for the detailed assessment of damages in composites (as surface defects, hidden voids, delaminations, fibre pullout).
