Evolution of the Airbus family Page a world of innovation 9,175 orders 300 customers 5,366 delivered to date 453 delivered in 2007 Evolution of the Airbus family Data to end Sept 2008
European Roots with global outreach Page a world of cultural diversity 1 global company 3 customer support centres 4 training centres 5 spares centres 9 engineering design centres 16 manufacturing sites 20 languages 24 hour customer support (365 days a year) 50 flight simulators more than 88 nationalities 160 offices 298 customers 290 resident customer support managers 296 operators More than 5,000 aircraft delivered 56,000 employees
Though Life Costs Page Through life costs If we can’t afford it don’t build it? David Gore Airbus UK, 2008 When we mean to build, we first survey the plot, then we draw the model; and when we see the figure of the house, then we must rate the cost of the erection; which if we find outweighs ability, what do we then but draw the model in fewer offices, or at least desist to build at all? William Shakespeare Henry IV, Part 2,1.iii, 1598
Through Life Cycle Costs, Why are they important ? Page
Reductions in greenhouse gas emissions to prevent global warming
Reductions in Noise output
Through life costs
Diminishing world resources
Fuel & commodity prices will only go up
Recycling & or disposal will become more important
Understanding the drivers for these is key
To enable Airbus to meet these challenges.
To enable Airbus to maintain its position.
Possibility that authorities will legislate to achieve these, probably through increased taxation. Mitigating the Risk and realising the opportunities associated with these will become increasingly important.
Because our Customers are asking for it Page easyJet has become the first airline to outline the environmental requirements that must be met by the next generation of short-haul super-clean aircraft; and unveiled its design of what such an aircraft could look like for operation by 2015. Dubbed the “easyJet ecoJet”, the aircraft would need to be 25% quieter and would emit 50% less CO2 and 75% less NOx than today’s newest aircraft (the 737 and A320 families of aircraft). Rear-Mounted ‘open rotor’ engines for short haul flying due to their efficiency A lower design cruise speed to reduce drag and a shorter design range to reduce weight Noise reductions to come from a gearbox between the engine and the open rotor blades Airframe to be made of advanced materials such as carbon fibre Key features include: Through life costs
What does this mean ? Page Evolution or Revolution: The history of Aircraft design has arguably been one of conservative evolution, however the problems addressed previously require a revolution. Through life costs The problem Airbus and other design professionals face is not so much a lack of ideas; ideas are historically what designers have been best at providing. The task facing designers today is in dealing with ‘limited resources’ in such a way that the optimum design is chosen.
Understanding the Challenges Page
Low cost of operation
Superior reliability / maintainability
Comfort / health driven cabin design
Low cost of acquisition
Low manufacturing impact
Integration in the System
Good airport compatibility
Through life costs
What do we need to do. Page We need to develop high levels of competence in the area of cost control and cost awareness, to enable our new design to meet these challenges, for example:- Through life costs
Development costs and over runs effect Low cost of acquisition.
There may be restrictions on travel as resources run out, we need to address this now with our future designs, however these must be cost neutral.
We must be able to balance the benefits of a technology with respect to performance, against the cost to implement.
We must be able to balance the benefits of a technology with respect to operating cost, against the cost to implement.
Addressing the challenge – current initiatives Page Airbus participating in the multi partner Integrated Wing project. This programme is of particular importance as it addresses the step changes called for by the The Aerospace Innovation and Growth Team (AeIGT) and the Advisory Council for Aeronautics in Europe (ACARE), set up to form partnerships between Government, Industry and Academia, under the heading of working together to ensure the competitiveness of the UK Aerospace Industry over the next twenty years. Airbus, Design to Cost Department collaborating with Queens University and QinetiQ: To create an integrated “Life Cycle Costing” model that will allow project partners to evaluate the impact of technologies being evaluated in the project. How: By creating a Knowledge Landscape that provides a Life Cycle cost modelling framework, where competing technologies can be evaluated. Resulting in the capability to trade off performance improvements against cost, and enable informed judgements to be made. Through life costs

Without penalising the customer.

The user may now specify and Apply a targeted improvement in reliability.
It should be noted that as expected the number of missions has increased.
However due to the cost increase to implement the Airlines IRR has reduced
Active Health Monitoring (Find Cost) Page Step 3 The model is now used to find the cost increase that this technology will bear to recover the Airlines IRR
Future Initiatives & Conclusions Page Airbus is leading the MDOW research and technology programme in collaboration with 15 leading British industrial and research companies to develop low-cost manufacturing methods that will enable high-volume wing manufacture for next generation aircraft. Future design processes will help reduce airline operating costs, airframe weight and maintenance. The programme will build upon, develop and enhance current knowledge both in the materials and especially in enabling rapid and cost-effective manufacturing whilst maintaining their excellent weight performance and the eco-efficiency benefits these bring to the Through Life Cycle Model.

and finally Page to bring the presentation to a close a short video that I hope you will find of interest: and finally finally what was the weight of the wing on the crane ? 24.6 t
