The main objective of HUC is to improve the buy-to-fly ratio from the typical ratio of 9 that is achieved through the conventional cast and wrought route to a ratio lower than 3 through near net shape hot isostatic pressing (NNSHIP), while ensuring that the material developed is able to withstand relevant engine conditions with and without exposure, thereby guaranteeing its ability to contain.

This project is a response to the call for proposals under the Clean Sky 2 Joint Undertaking to manufacture IP turbine casings for the new generation Ultrafan® engine made from Astroloy using net shape hot isostatic pressing (NSHIP) with metal powders. Five partners are involved with the project, providing complementary expertise in the areas required to undertake the work, including powder manufacturing and characterization, NSHIP and modeling, low cost tooling, and microstructural and property assessment.

Ceit's role in the project

CEIT´s role in HUC is to serve as project coordinator and be primary lead on innovation activities in WP1 (optimization and validation of the powder cycle), WP2 (material design data), WP4 (process modeling) and WP7 (validation). In addition, Ceit leads WP8 (which is related to management, and collaborates on WP3 (containment capability), WP5 (low cost canning tool) and WP6 (manufacturing of the casings).

The main activities Ceit performs for HUC are based on Ceit´s expertise in powder design, atomization and characterization and in applying the NNSHIP route for aeronautical components. Ceit also works on modeling the behavior of powder during HIP.
