2 Nondestructive Research In Service

Innovation Track 2 

The innovation in this track is symbolized by combining the different nondestructive testing techniques plus the data sampling of the results to paint one reliable overall picture. A component of this track is performing a nondestructive scan by a robot to ensure high accuracy.


TiaT’s activities are mainly focused on the operational nondestructive evaluation (empirical research) and the University of Delft concentrates more on experimental and scientific research. In short: If empirical results can be scientifically underpinned. The final goal is to develop a reliable, fast and automated nondestructive evaluation scanning method for large surfaces. 

Parties involved: TiaT Europe, NLR, Specto, TUDelft.

Questions answered in 2018

1.     Which nondestructive evaluation methods are suitable for composite materials?

2.       Under what conditions can these nondestructive evaluation techniques be used?

3.       How does the thickness of materials, form/complexity and placing in the aircraft affect the evaluation process? TiaT is partly dependent on third parties for their composite testing materials.

4.       Which sensors for the particular nondestructive evaluation techniques are suitable for which constructions of composite?

5.       Which combination of nondestructive evaluation techniques gives an acceptable detectability? 

6. 1.       How can automated data sampling of research results with several nondestructive evaluation techniques on an object take place?

2.       Inspection of a repair of composite material.

3.       Which (under development) robot is most suitable, or can be made suitable for a universal head where several nondestructive evaluation equipment can be placed into?

4.       How accurate can the (head of a) robot follow the contour lines and therefore how accurate is the positioning and the reproducibility of a scan?


5.       Can there be permanent contact via a tool between a sensor and the surface of a jet? And can that be ensured by automatic ultrasonic inspection with the help of the robot?
