Good forecasts

For the year ended 2018 we are proud of having developed a good job and having achieved new milestones for the Andalusian aerospace and technology sector, but more importantly, it starts a new one, 2019, with the feeling that we have a very promising future ahead. Not only for our center, but for all those who participate in the aeronautical industry and the innovation environment and technological development linked to this sector, which boosts the economy in our community.

In our specific case, new horizons are opened with the participation in new European projects such as SAFEDRONE, DOMUS, RIB-AM or RIMA, all of them linked with the development and application of new technologies of unmanned systems (drones) for their integration in airspace or implementation of new advanced manufacturing systems (such as 3D printing) for the aerospace industry. Also with the organization of important events like the hosting of the II International Tournament on Emergency Service Robots of the European Robots League (ERL), which will take place in our facilities in Seville next February.

We must highlight another unprecedented milestone in Andalusia, such as the Presidency of Seville of the Community of Ariane cities for 2019, an event in which FADA-CATEC collaborates and which will mean that the city of Seville becomes the ideal showcase to demonstrate the potential of our sector and the focus of attracting investment and business opportunities to boost our companies and technology activities in the field of space, through the environment offered by the so-called New Space. This event will have a program full of activities that will also serve for the scientific dissemination of what the Space sector represents and the applications that the whole society enjoys today thanks to the development in this field.

We have, therefore, an exciting year ahead, full of good forecasts and new challenges and illusions for both the Andalusian and Spanish aerospace sector. Let us take advantage of this to continue working among all of us - industry, administrations, technological agents and social agents - to keep on growing and positioning it as one of the most relevant in the European and international environment.

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.
