Further development of eddy current corrosion sensor for aerospace applications

Functie

The internship assignment

The costs of corrosion maintenance of military aircraft are roughly 25% of the total maintenance costs. The down-time for corrosion maintenance adds to this high costs. A more efficient corrosion maintenance concept, where maintenance is performed when it is required instead of preventive based on educated guesses, would improve availability of aircraft. To implement such a maintenance concept tools are required that enable the monitoring of corrosion and thereby enable an early warning for corrosion maintenance.

A first prototype of an eddy current corrosion sensor is developed in a PdEng project. A number of sensor elements is made and the proof of principle is shown. Now the characteristics of the sensor elements, including their sensitivity and the applicability on non-planar surfaces needs to be investigated.
The work will consist of selecting the best equipment to be used with the sensor elements, analysing the signals and interpretation of the signals in term of the damage detected and the sensitivity of the sensor.

Enthousiasm to fully understand an analysis technique and to find the optimum parameters is needed for this assignment. In return a high-tech environment with sparring partners with different backgrounds is offered.

Result

Eddy current corrosion sensor with known accuracy and applicability for corrosion monitoring of aircraft components.

Duration of the assignment

To be agreed, at least 3 months.

Profiel

Informatie

Your internship company

Royal NLR has been an ambitious knowledge organisation for more than 100 years. We aim at being innovative and make air transport safer and more sustainable, efficient and effective. We are at the base of breakthrough technologies. Plans and ideas may become reality when given the right appreciation. More than 600 enthusiastic professionals are working on research and innovation. Specializations range from aerospace engineers to psychologists and from mathematicians to application engineers. Our site in Amsterdam has been renovated recently, while a brand-new building is realised in Marknesse.

The work will be a cooperation between NLR Marknesse and TUDelft (chair of Corrosion Technology and Electrochemistry).
