COPPER Bird
The COPPER BIRD® was created in 2002 to meet the needs of more electrical aircraft, in the context
of the POA (Power Optimised Aircraft) European project to characterize an innovative electrical
architecture and define a new integration methodology for Electrical Aircraft Equipment. With Clean
Sky the Labinal Power systems’ test rig is in its final phase, in accordance with airframers new
requirements, in order to create a new ground Electrical Test Bench for small aircraft and helicopters.

Assessment
Using a reference aircraft, on a standard mission, the
comparison of a Conventional Architecture vs. an Electric
one is possible.
The assessment identifies those system components with
penalties in terms of weight, but balanced by gain at overall
architecture level.
Only by collaboration of systems suppliers and airframers
at architecture level, the assessment is realistic.
Most recent statement by Airbus:
MEA architecture still in strategic axis but postponed

 Clean Sky is contributing to the achievement of the ACARE environmental
target of Vision 2020 and preparing the development of technologies for
reaching Flightpath 2050 targets; it has allowed the continuation of
projects about More Electric Aircraft of FP6 and FP7 like POA and MOET.
 Clean Sky keeps its fundamental role in funding of demonstrators for next
years, covering the More Electric technologies and architectures (from
power generation and distribution; to actuators; to new electrical
systems; wing ice protection.
 Only by collaboration of systems suppliers and airframers at architecture
level, the assessment is realistic.
