Aerospace Technology 2010, Stockholm,

Towards a High maturity

 Demonstrators definition close to the market needs: the demonstrator is the last R&T phase, before starting a development

 Schedule is key to keep this link (be neither too early, nor too late)

 A large part of this downstream research activity lays within big players, « integrators » - a typical feature of aeronautics

 These activities must be thoroughly coordinated A large programme focused on environment… 

 … and compe++veness 

A high level of « technology readiness »: the technologies are integrated into large demonstrators, in-flight or on-ground

These features create the condi0ons for a Public‐Private Partnership

►Management of Aircraft Energy (MAE) branch of SGO ITD encompasses all aspects of on-board energy provision, storage, distribution and consumption

►MAE aims at developing electrical system technologies and energy management functions to reduce fuel consumption and overall aircraft emissions through:

• Development of all-electrical system architectures and equipment

• Validation and maturation of electrical technologies to TRL 6 by large scale ground and flight demonstrations.
