“Advanced FOrging of an Optimized Turbine casing (AFOOT)” project - Clean Sky Joint Undertaking

Since October 2013 RTM Breda has been the coordinator of the “Advanced FOrging of an Optimized Turbine casing (AFOOT)” project within the Clean Sky Joint Technology Initiative.

The objective of this project is to determine and validate a robust set of forging and heat treatment parameters leading to the forging of a fan case for a geared turbofan demonstrator as part of the Sustainable and Green Engine (SAGE) platform by making the microstructure of ATI Allvac Alloy 718Plus stable against overaging effects occurring during long-term exposure at 700°C.

This project represents the collaborative effort of an experienced company specialized in forging and ring-rolling of superalloys, Forgital Italy, and a technological research center with great competence in thermo-mechanical processes analysis and modelling, RTM Breda.

Development of an advanced predictive simulation modelling tool is a pre-requisite for the success of the project along with a thorough laboratory measurements campaign that will be performed to test the original material as well as the material overaged in conditions similar to those it should work at.

The final outcome of the project will be the production of three fan cases whose design will be agreed upon with the topic manager, MTU Aero Engines, one of these cases will be cut up and properly examined in the lab while the other two will be delivered to the Topic Manager.
