TiAl alloys have successfully been introduced in civil aircraft engines over the last years and a significant order volume increase is expected in the near future. Due to its beneficial buy-to-fly ratio, investment casting bears the highest potential for cost reduction of all competing production technologies for TiAl-LPTB.
In the last decade, Access has developed and optimized investment casting technology especially for the production of TiAl-parts. While these parts meet highest requirements, establishing series production and further lowering internal scrap rates are present challenges. In order to meet these goals, Access is being certified according to Aircraft Standards, aiming at qualifying produced parts on Technology Readiness Level 6. The present work gives an overview over the phases of development and certification. A generic blade is used as a demonstrator to address design and process and to demonstrate the steady quality improve to meet required specifications.
