Noter que les boitiers de transmission (Accessory gearbox) sont bien compliqués et aussi une source de développements et d'économies de poids ! Et parfois d'ennuis aussi CF les 77W d'AF à une époque !
Hispano Suiza du groupe Safran, est en charge pour le Trent XWB de RR !

Trent XWB turbofan engine: the A350 gets a power boost
11.10.2010
Safran has been selected to supply the power transmission system for the Trent XWB, the engine to equip the future Airbus A350 XWB. Olivier Horaist, CEO of Hispano-Suiza (Safran group), discusses just what this program means.

Can you remind us in just a few words exactly what is a power transmission system, and how important is this program for your company?
The power transmission system is used to channel off part of the engine’s power in order to distribute it to various other equipment needed for the operation of the engine and of the aircraft, such as the fuel pump and the electric generators. It is a complex and critical system that incorporates over 400 component references spread across several subsystems: internal gearbox, step-aside gearbox, accessory gearbox and oil tank. Even though we are already one of the two world leaders on this market, this program is somewhat daunting in a number of respects. First of all, this is the first time that an engine manufacturer has entrusted us with the development of the entire system. Secondly, we shall entirely responsible for the activity as a whole - including support - and for the entire lifecycle of the engine, in other words for some 40 years or so! Lastly, this will also be the first time that we’ll be providing such a service to such a major fleet. Even before its service launch, over 550 Airbus A350 XWBs have already been ordered, which means over 1100 engines! It is therefore a program of major structural significance for our company.
