Extending the Use of Titanium Alloys on A350XWB
The constantly increasing expectations of Airlines in terms of environmental impact limitation,fuel consumption efficiency and reduced cost maintenances strongly incite AIRBUS to always push forward the limits of innovation on its airframes. Particularly, the new A350XWB is characterized by the massive use of CRFP on its fuselage structure. For both thermal dilatation compatibility and corrosion resistance, this introduction of CFRP induced the extensive recourse to titanium alloys and the related technologies. Indeed, their use has nearly doubled to reach about 20％ of the structure weight,compared to 10％ on A3801,2, This paper deals with the structural applications of Titanium alloys on the different areas ed to novelties on both pylori and fuselage. The reasons of the choices of the different alloys used are detailed in regards with the technical requirements. The advantages and the drawbacks of the associated forming and assembling processes are compared,in correlation with the main processing obstacles. Some innovative forged,cast and super-plastic formed parts are highlighted. At last, the major stakes in terms o new metallurgical developments, research cooperative programs and typical processing problems of titanium parts are described.
