SRC cluster in EP Incremental Line Status and Next Steps

• EPIC-SRC cluster in Electric Propulsion has supported several technologies, today we can say is a success, supported by major contracts in the US market for HET and GIT

• EPIC- SRC cluster in Electric Propulsion is well covering the gaps, it is very important to European industry

• SRC cluster will answer to LP, MP and HP PPUs future needs, clearly the next step

• PPU is the main cost contributor for a recurrent EP system:PPUs cost reduction is a key element to increase EP systems competiveness, and PPU budget in SRC

cluster shall be well balancedIts is crucial to invest on certain technologies where there is still a technology gap: HV technologies, GaN,

COTs, industrialization…

EP market is evolving, EPIC-SRC cluster in Electric propulsion is the right tool to prepare European Industry for EP future trends
