Boeing 787 Dreamliner electric brake
Thirty years after introducing carbon brakes on commercial jets, and now the market leader, Messier-Bugatti-Dowty brings electric brake technology to airframers and airlines alike. Electric brakes are now available on the Boeing 787 Dreamliner.
Advantages of electric brakes
“Plug and Play”: because electricity replaces traditional hydraulic lines, electric brakes are easier to install andmaintain.
“smart” features to facilitate airline operations: continuous, real-timemeasurement of carbon disk wear, readings displayed in the cockpit, etc.
Messier-Bugatti-Dowty electric brake: a competitive edge
lighter than its competitor: reduced weight while maintaining excellent thermal capacity.
Better brake reliability
. zero load sensors
. low sensitivity to Foreign Object Damage
. all stators fitted with steel clips
simplified maintenance: electric motor and actuators are independent (LRUs) and can be removed separately.
longer brake life: a 4-rotor brake configuration combined with Sepcarb® III OR (Oxidation Resistant), enhanced with a new ‘Anoxy66’ anti-oxidation coating for better protection from deicing products.
Worldwide support: a dedicated Messier-Bugatti-Dowty avionics repair network to handle electronics (EBAC)maintenance:
. in Dallas for the American market;
. in Singapore for Asia-Pacific;
. in Massy, near Paris, for Europe, the Middle East and Africa.
Greener technologies
Messier-Bugatti-Dowty is fully committed to the production of environmentally-responsible wheels and brakes, including:
reduced CO2 emissions and fuel savings, thanks to weight optimization of up to 141 lbs (64Kgs) per 787-8 aircraft and 244 lbs (111Kgs) per 787-9 aircraft.
the system itself, which is 100% cadmium-free, chromium-free, beryllium-free (silicon bronze brake bushings) and asbestos-free (stainless steel or titanium insulation);
the production process for wheels and brakes: solvent-free (water-based paint topcoat, low-volatile organic compound primer), no chlorofluorocarbons or halons used anywhere in the manufacturing process, including by suppliers.
