X-59 QueSST de la NASA : Exxelia est à bord

Ces dernières semaines, la NASA a beaucoup communiqué sur son programme d’avion expérimental X-59 QueSST, dont le démonstrateur arrive en fin d’assemblage chez l’avionneur Lockheed-Martin. Maillon essentiel du projet Low Boom Flight Demonstration (LBFD), le X-59 entamera ses campagnes d’essais.

Si le programme tient ses promesses, il pourrait permettre l’émergence d’avions de transport supersoniques capables de voler au-dessus des terres, sans les limitations imposées au Concorde en son temps.

Pour ce projet, Exxelia produit principalement des bobines en provenance de nos sites USA. Nos composants sont à destination du moteur de l’avion.

 

 

Avec son nez allongé, ses ailes “bossues” et ses petites surfaces portantes dispersées, le X-59 ne ressemble à aucun autre avion.

Il volera à une vitesse de 1,5 Mach (1,5 fois la vitesse du son), soit plus de 1 800 kilomètres par heure. La NASA espère que son appareil pourra, à terme, être utilisé dans le domaine de l’aviation civile.

 

Si les essais sont concluants, le X-59 QueSST pourrait donc avoir deux effets révolutionnaires sur le paysage aéronautique américain, voire mondial :

  • L’avion d’essai pourrait servir d’inspiration à de futurs avions de transport produits en série, qu’il s’agisse d’avions de ligne ou d’avions d’affaire.
  • L’ensemble du projet LBFD pourrait permettre une évolution de la réglementation aérienne actuelle. Plutôt que d’interdire tous les vols supersoniques civils au-dessus des USA, comme c’est le cas aujourd’hui, la NASA propose d’instaurer une réglementation en fonction du niveau de bruit.

Exxelia's Smart Magnetic: Breakthrough technology for more compact and powerful converters

This advance makes it possible to design more compact, lighter converters. However, the advantages of this technology are not limited to these fundamental aspects. In this article, we will explore in detail the multiple functional, economic and environmental benefits offered by Exxelia's Smart Magnetic technology.   Functional advantages for increased reliability: The Smart Magnetics project makes it possible in particular to optimize the Dual Active Bridge topology which requires the combination of a transformer and a choke. The Dual Active Bridge converter is a technology that is becoming widespread because it allows bidirectional power transmission. This meets the challenges of electrical systems (recovery + supply of energy), Integrating the Dual Active Bridge (DAB) transformer and choke into a single component has significant functional advantages. Unlike assembling two separate components, using an integrated component eliminates interconnections. The repeatability and reproducibility of the processes guarantee perfect control of the electrical characteristics, and ensure optimum performance of the converter. In addition, this consolidation reduces the number of components required, which improves the reliability of the final product.   Rationalization of the value chain for optimized production costs: The Smart Magnetic project also contributes to improving the value chain through effective streamlining. By replacing two distinct components with a single component, the management of the components of the circuit is simplified. From the customer's point of view, there is only one product to supply, one product to integrate/assemble in the system. These simplifications result in high added value and increased competitiveness on the market.   Contribution to a more environmentally friendly industry: By adopting Smart Magnetic solutions, the benefits go beyond simply improving energy efficiency. This innovation also reduces the consumption of raw materials by using less material in the Smart Magnetic component compared to standard formats requiring two separate components. As a result, this technology contributes to the preservation of natural resources. In addition, Smart Magnetic responds to the challenges posed by the electrification of vehicles, whether in air, land or sea transport, by promoting the deployment of solutions that are less dependent on fossil fuels.   Various applications: The versatility of Smart Magnetic solutions makes it suitable for many applications. For example, it can be used as a bi-directional converter between batteries and circuits, for power applications or even in resonant converter topologies. It is also useful in applications requiring high current and in Multi-output flyback converters. This diverse range of applications testifies to the flexibility of the Smart Magnetic project.   A project ? Do not hesitate to contact us.    

CUBISIC HTLP : Exxelia expands its range of low profile aluminum electrolytic capacitors

June 7, 2022 - Paris, France - Exxelia, a global manufacturer of complex passive components and subsystems for harsh environments, is expanding its CUBISIC capacitor range with a HTLP (High Temperature Low Profile) version. This CUBISIC HTLP offers, in a thin rectangular packaging, the highest energy density of capacitors in its class, combined with a high temperature resistance (-55° → +125°C).    CUBISIC HTLP, the new rectangular capacitor range that changes the game  The new range of CUBISIC HTLP by Exxelia clearly stands out! Why?  It offers up to 60% more capacity than any other rectangular electrolytic capacitor on the market, in the same volume, while having a 5,000-hour life span. Covering a temperature range of -55° → +125°C, the CUBISIC HTLP is designed to provide excellent performance in extreme temperatures, compatible with the most severe military and aerospace applications.    Engineers facing complex design requirements and looking for an easily integrated product will gain space and reliability through the use of improved materials fully REACH compliant. The CUBISIC HTLP withstands 20g vibration and is low-pressure qualified, making it compatible to 92,000 feet in altitude. It is ideally suited for integration into cockpits, actuators, and power generation in commercial and military aircraft as well as radar and laser systems.  TECHNICAL SPECIFICATIONS : Capacity from 140μF to 58 000μF Voltage from 7.5V to 350V Service life of 5,000 hours at 125°C Operating temperature -55°C to +125°C 20g vibrations and 92,000 feet altitude  RoHS versions available
