Due to reduction of losses and optimisation in aircraft designs, aircrafts are more electrical. This perspective takes place in an environmental respect context. One main goal of CleanSky project was to improve Systems for Green Operations (SOG). Management of Aircraft Energy (MAE) was one of the most important challenges. HDSPC project took place in this context.

In these kind of specific products, EUROFARAD heritage in plastic film capacitors was fundamental. Moreover, a good comprehension in customer requirements (mechanical, electrical, thermal …etc.) was essential for the actual demand but also to understand problematic for future design. Management of aircraft energy led EUROFARAD to focus on the same goals as our customers:

• Higher working temperatures;
• Higher energy density (also means weight reduction);
• Possibility for sensing capacitors for self-diagnostics (lifetime and control).

During HDSPC project, our main goals were to improve our technology in term of working temperature and miniaturisation. Special attention was paid on material analyses and choices: both plastics polymers for capacitors but also capacitor covering materials in aeronautics environment. Moreover, R&T was done on the SMART capacitor, with the main goal of providing physically integrated (into the capacitor) solution for sensing “state of the capacitor” under electrical control signals.
