Superplastic forming (SPF) has received considerable attention because of weight andcost savings and high possibility in aerospace applications. The requirement of modernindustry and especially production of business aircrafts request high mobility ofproduction, high changeability of models, short period for organisation, new technologiesfor tools production. SPF is the solution to this requirement and open new opportunitiesfor design of integral parts of aircraft structure.Now Israel Aircraft Industries Ltd. (IAI) uses SPF for the production of integral aircraftparts in new business aircraft. The main opportunity to use the SPF technology arousefrom the needs of a new technology in producing integral-shaped parts for the new modelof IAI aircraft “G-200”. Sheets from titanium alloys have many attractions for theaerospace industry due to their high strength, low density, heat resistance and other usefulproperties. Many of the sheet metal structures in airframes have complex shapes andcompound curvature with intricate details. The air condition disposal in the tail ofairplane “G-200” requires the creation of a fire-resistance and structural parts.The application of SPF technology can reduce markedly the manufacturing cost byeliminating details needed for the assembly and by that reducing the preparation time andthe need for extensive welding or joining methods. The use of a low temperature superplastic forming operation reduces the amortization of the forming tools and lessexpensive materials can be used. This paper contains results of our research and practicalapplications the new design on base of SPF techniques and the new titanium alloy.
