The strategic drivers for energy management systems
• Product performance: 900-600 KW
Operational efficiency of the end-to-end
p y
energy management chain
15 models
Availability of energy management functions 300-200 KW
> 9,500 aircraft sold

Vision towards “Total Energy Management”
• Target concept:
p
platform based energy management, with shared resources
gy g
managed efficiency of the end-to-end energy chain
well sized power demand, dynamically managed loads
minimized and dynamically managed thermal losses
managed energy systems health and life-cycle
• Attractiveness of the All-Electrical Aircraft Systems:
single source of energy ☺ ☺
homogeneous product line ☺ ☺
mutualized resources ☺- ☺
embedded intelligence ☺
Cost!
modular components ☺ ☺

Progress status from European R&T projects
1. The All-Electrical concept is feasible, but the simple replacement of
conventional technologies by electrical ones is not bringing benefit.
2. Promising airworthy architectures are identified, but the quantified
benefit is not demonstrated yet in all conditions with enough
confidence and maturity.
3.
3 Among promising All Electrical and Hybrid architectures the dominant
All-Electrical architectures,
trade-offs are primarily driven by architecture choices, not technology.
4. The
4 Th current level of performance of the electrical components and
tl l f f f th l t i l t d
technologies is not good enough to deliver robustly the benefit of the
architectures, but positive trends are emerging in R&T.
