Review of the fifth edition of the SPEC symposium

An essential bi-annual meeting for all the key players in the “more electric aircraft”, the fifth edition of SPEC (Safran Power Electronics Center) was a great success.

Almost 240 people (customers, industrial partners, research laboratories and PhD students, official departments, representatives of Safran companies) took part in the 5th edition of the SPEC symposium, Safran's power electronics hub for a more electric aeroplane on 3 and 4 December 2013 at the Palais des Congrès in Versailles (near Paris).

These two very intense days were punctuated by ten sessions led by Safran experts during which forty Safran engineers, researchers and PhD students talked about their work on all the issues of R&T electrical systems. The following issues were covered:

  • environmental constraints,
  • the architecture of networks and related issues in the area of energy management, stability, protection, cabling and storage,
  • components and converters,
  • training architectures,
  • electrical generators.

Alain Coutrot, Safran Deputy Director of R&T, says this edition reflected Safran's great technological advances towards the more electric aircraft, and made particular reference to the appropriation of academic work by Safran technologists: SiC technology converter (silicon carbide power components), improvement of motor windings, improvement of cabling taking into account the effect of lightning, as well as electro-magnetic compatibility (EMC) constraints.

SPEC5 was also marked by the traditional posters session. With over 75 posters and a large number of exhibitors and prototypes on show, researchers, industrial partners (suppliers of components and packaging solutions, and also groups such as Renault and Valeo) and Safran specialists presented and discussed new directions in ground-breaking technologies. Very appreciated by customers, this posters session provided participants with an opportunity to talk to representatives of Airbus, Boeing, EADS and Dassault Aviation, potential users of the technological solutions presented.
