MBD: the move to more Titanium for Twin Aisle Programs  On Twin Aisle programs (A350, B787) the Key Parameters are:  Weight reduction  Reduction in airframe mass reduces fuel needed to “fly the airframe”  Lower fuel burn = reduced C0 2 output “Greener”  Direct Maintenance Cost  Corrosion rectification  Extended maintenance/overhaul intervals  The materials choice has a major influence on program:  Structural: through the adaptation of designs to the materials properties - low stiffness and fracture toughness in-particular  Cost : $/kg has direct effect on the economical objectives  Industrialization: need for new tools and manufacturing processes  Quality: important to maintain control of the whole process including melting, forging, heat treatment etc. to achieve high quality final component

MBD: the move to more Titanium for Twin Aisle Programs  Alloys currently in use:  Ti 6-4, Ti 6-6-2 Intermediate Strength  Ti 5-5-5-3, Ti 10-2-3 High Strength  Consumption to increase by an order of magnitude and will approach current usage of low-alloy steel (largely 10-2-3 and 5-5-5-3) by 2015

Titanium Supply Chain Developments opportunities for MBD  Requirement for over 2 000 tonnes of high strength titanium per year ( for structural components on twin aisle programs only )  On average, 75% of Forging is removed for final detail parts: high Buy to Fly ratios  MBD interested in improved near net shape processes  Limited worldwide Supply Chain for High Strength Titanium (for MBD)  Currently no Titanium Supply Chain in UK  MBD Gloucester is a Safran worldwide Centre of Excellence for Titanium Machining ( continuous development of expertise through TSB funded projects and through extensive collaboration with Catapult Centres )  MBD will benefit from a more local Supply Chain specialised in Titanium: Asset for UK Aerospace Industry
