The Project GREENBARRELS aimed to find out a way to produce 360º components for aircraft engines by spinning methods, such as: spinning lathe, flowforming, shearforming. In particular the manufacturing of barrels for CROR propellers of SAGE2 ITD was assessed. The materials to be used for this development were Inconel718 and Titanium Alloy.

Thus, the project looked for a cost effective way of producing barrels of about 1 m. diameter in these alloy. The project included barrels design and looked to verify compliance with certification requirements of design and process. The aim was to get a process to replace intensive energy consuming processes and also to get a process with almost non-waste material.
