Participation in the "Industry of the future" program by GIFAS

On Tuesday January 4, 2022, Exxelia participated in the launch of the second wave around the "Industry of the future" program for the Grand Est region at the Bologna site of LISI AEROSPACE.

GIFAS"Industry of the Future" Program

Launched in 2019, for four years, financed by the government, as well as the Regions, OPCO2i, companies and GIFAS: the "Industry of the Future" program aims to strengthen the competitiveness of the sector through the introduction of new 4.0 technologies. This program, which is the result of close collaboration between the Industrial Committee, the GEAD and the AERO-PME Committee, is a continuation of the "Industrial Performance" program. Its objective is to use new digital and production technologies in all phases of a product's life. In this respect, the Exxelia sites of Illange and Marmoutier are concerned.


Frédéric BOIS, in his capacity as Director of the Exxelia site of Illange, was able to actively participate in the exchanges. The objectives were numerous, namely : 

  • Inventory of the industrial maturity of our site of Illange.
  • Analysis.
  • Recommendation and deployment of Industry 4.0 tools best suited to the situation of each company.

 

Thanks to the Grand Est region which contributes to the financing of the program, to the partners: Cetim - Technical center of mechanical industries, BoostAeroSpace SAS, UIMM, DREETS, OPCO 2i, and of course to AERIADES as a facilitator of the aeronautical sector in the region.

Larger Batches of High Q-Factor Dielectric Resonators

Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q-factor and the possibility to get all the temperature coefficients upon request. E7000 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication. Typical applications for the E7000 series: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.  

NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM

Working frequencies in Space applications are shifting to Ka, Ku or even Q band, while cavity filters are undergoing the general trend towards miniaturization: this context calls for a much more precise and stable tuning element now offered by Exxelia Temex, daughter company of Exxelia, through their last innovative and unrivalled solution to incorporate a self-locking system into their Invar Tuning Elements. Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.
