Quoting Mayohoo (Thread starter): How will the a350 differ in both engine design (RR of ocurse) and electrical architecture?
The engine architecture will be very similar; the only major difference is that the A350 will have a full bleed system on the engine.
The electrical system, on the other hand, will be quite different. Airbus elected to stick with a pneumatic system on the A350, which relieves the electrical system of considerable load requirements and takes a bunch of motors, power controllers, and power handling out of the system. In return, they have to keep the pneumatic ducts, valves, and overheat/leak detection systems. This also bleeds over to the APU; the A350 APU will need both generators and a load compressor (the 787 APU only has generators).
