Large scalE Integration demonstrator of hybrid electrical Architecture (LEIA)

LEIA is fundamental in the context of Clean Aviation’s strategic goals to reduce greenhouse-gases emissions and advance green aviation technologies. This challenge is often associated with propulsion technologies or disruptive wing configurations, but it is not limited to that, and both pathways are enabled by novel system technologies and architectures.

LEIA is essential for preparing the future short-medium-range aircraft more/hybrid electric non-propulsive energy architecture. It aims at designing and integrating non-propulsive electrical systems to enable an increased engine off-take efficiency together with a more flexible energy management, while minimizing the overall system sizing.
