With steady pace to Le Bourget

We are practically in the half-way point of the year fulfilling with a firm step the strategic line that marks the course of our team, that is none other than to continue driving the R&D in the aerospace sector, for its real application in the industry, and to help our business to increase its technological competitiveness that is so important in a global market, like aviation is. In these months we have started new projects of national and international state-of-the-art, we have worked with companies to move forward in the improvement of its technological innovation, we have participated in conferences and meetings with companies and organizations in the sector and we have even supported administrations to help diagnose and define strategic plans for the development of the aerospace industry and the economy for the next few years.

With this good work, and backed by our trajectory in the last decade, FADA-CATEC is attended Paris Air Show Le Bourget, the largest aerospace world meeting in which big companies, contractors and agents involved in the development of new technologies in this field meet together in just a few days. And we have participated in the Andalusian official delegation that travelled to the neighbouring country in order to bring value to the evolution and growth of our industry, but also to project the great potential for the future.

As we have been doing in recent years, we went to Le Bourget with the aim of presenting our latest technologies, services and advances in R&D for the sector, to strengthen our ties with the companies and assisting organizations (partners or potentials), as well as to detect and analyze opportunities for technological collaboration that they can capture in new projects for our team, but also involving the participation of Andalusian and Spanish companies.

The work and cooperation between research institutes and companies continues to be fundamental in order to contribute greater added value to our products and services, and that is why we must not neglect to take advantage of this type of events in order to reinforce our position as a point of reference in the international aerospace outlook, and, above all, continue to be the driving force.

SHM is a set of techniques aimed to minoring the health of structures during their useful life. This monitoring detects some changes in the material or in the geometric conditions of the system that may negatively affect their qualities.

This process is organized in four levels:

1) Determination the presence of damages in the structure.
(2) Geometric location of the damage.
(3) Quantification of the intensity.
(4) Prediction of the remaining life of the analyzed element.

In order to perform all these actions it is required a network of sensors distributed on the structure under examination and connected to a central system that provides real-time information on the state of the component, such as fiber optic technology and FBG sensors.

The FBG (Fiber Bragg Grating) sensors basically consist of a "marking" that is included directly on the lines of optical fiber (marked of Bragg). The behavior of the Bragg sensors is analogous to that of a filter, that is, it reflects a certain wavelength of light that illuminates the optical fiber and lets the rest pass. By changing the wavelength reflected by the sensor it is possible to determine the deformation state to which the structure is subjected. In addition, the same fiber optic line can contain up to about 40-60 sensors, drastically reducing the number of lines to be used to monitor various points on the structure.

CATEC is a specialist in this technology and has developed some solutions and tools for its implementation in service. The technology is available for both the sensing and monitoring of various structures and for the monitoring of structural tests.
