The changes to A350-1000 compared to A350-900 are described in this figure below:
The A350-1000, while essentially a stretch of the -900, will incorporate a number of aerodynamic and structural differences – including a 6-wheel main landing-gear and a larger trailing edge.
It will also have several other enhancements including greater use of composites in the fuselage frames and pylon, and electric landing-gear doors.
The A350-1000 is building on all the knowledge and data that Airbus has gathered on the A350-900.
With this experience and knowledge, Airbus has taken the chance to go one step further in a number of areas to gain further weight and reliability advantages for A350-1000, as shown in this picture:
Primary areas of improvements are:
- Airbus is increasing the Carbon Fiber Reinforced Plastic content of the aircraft gaining both weight and cost advantages by means of reduced structural maintenance requirements.
- Fuselage door surrounds and a portion of the fuselage frames were made with Titanium and Aluminium on A350-900. This will now be changed to CFRP.
- Airbus has also done some other improvements. The bilge area below the cargo floor has got a new frame support structure and the aircraft’s nose landing gear doors are now electrically instead hydraulically actuated, simplifying door installation and maintenance.
- Finally there are a number of clean ups on the electrical side with simpler solutions for the A350-1000, requiring fewer connections, something that saves both weight and sources of future trouble.
Airbus is also working hard on increasing the cabins passenger carrying capability.
