PARIS, FRANCE--(Marketwire - 20 juin 2011) - Bombardier Aéronautique a annoncé
aujourd'hui le franchissement d'une nouvelle étape dans l'exécution de son
programme de technologie stratégique pour l'aviation civile : un avion
Bombardier Global 5000 a effectué une série d'essais dans des conditions connues
de givre. L'appareil était équipé d'un système de protection antigivrage de bord
d'attaque en matériaux composites.

« Une des priorités stratégiques de Bombardier Aéronautique consiste à
développer des produits innovants et respectueux de l'environnement qui
répondent aux besoins des clients dans le monde entier. Nous sommes fiers de
nous engager à innover dans le domaine aéronautique » a déclaré François Caza,
vice président et chef ingénieur de Bombardier Aéronautique. "These successful
flight tests highlight Bombardier''s commitment to the advancement of aviation
technology. They are part of a comprehensive technology development program
covering various areas, including avionics, aircraft systems, advanced
structures and advanced manufacturing methods," he added.

The Electro-thermal Ice Protection System (EIPS) flight testing lasted in excess
of 35 hours, seven of which were completed with the Electro-thermal Ice
Protection System selected "on" in both dry air and natural icing conditions.
The main components of the EIPS are a Meggitt thermal solution with a Fokker
advanced material leading edge slat structure, incorporating Meggitt heaters and
ICE Corporation controllers. Extensive wind tunnel and icing tunnel tests were
conducted beforehand to support in-flight safety.

On board the test aircraft were Sam Gamar and Frank Magnusson, Engineering Test
pilots; Jeff Hyde and Laura Hilboldt, Flight Test engineers and Eduardo Freitas
and Kheira Aboubi, Thermodynamics engineers.

"We tested the EIPS in both dry air and natural icing conditions south of
Anchorage, Alaska, with great success. The system demonstrated structural
integrity and successful ice protection performance as anticipated from a more
efficient electrical system," said Peter Rawlinson, System Lead engineer,
Bombardier Aerospace.

"The demonstration of an Electro-thermal Ice Protection system is one step
further towards a "More Electric Aircraft" that will have electrical power as
the primary means to operate systems normally driven by less efficient engine
compressor bleed air," said Avraham Ardman, Chief Systems engineer, Bombardier
Aerospace.

Less than two years ago, Bombardier successfully flight-tested an all electric
braking system. This time, Bombardier''s strategic technology demonstrator
aircraft was modified by removing the bleed air ducting and leak detection
system from the most outboard slat, an eleven-foot-long span, on both wings. In
their place, an electro-thermal composite leading edge, incorporating Meggitt
heaters and an associated power harness, was installed on each wing.

The key benefits of this new technology are: an expected increase in aircraft
dispatch reliability; elimination of bleed-air ducting, valves, and leak
detection associated with hot bleed air duct failures. The new technology will
simplify the aircraft manufacturing and assembly processes and lead to reduced
maintenance costs for operators. It will also save energy and reduce aircraft
emissions, leading to a more environmentally conscious product.
