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 C02 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
Titanium for Landing Gears: application for future Single Aisle/Short Range aircrafts On future Single Aisle programs (replacement of A320, B737..) the Key Parameters are: Cost Reduction of landing gear cost through use of lower cost material (Steel 300M, aluminium..) Direct Maintenance Cost Reduction of corrosion through use of non-corrosive material / improvement of Special Processes Business Case is open for use of Titanium on such Programs : If titanium can be produced at lower cost (higher material cost offset by little requirements for Special Processes) If Buy to Fly ratio can be improved If titanium production lead time can be reduced High volumes programs need to be supported: 27,000 100+ seats aircraft by 2031, worth $3.7tr 24,000 business jets by 2031, worth $648bn Total civil aerospace market > $4.5tr
