The proposed BFA design is based on a hybrid approach: Ceramic Matrix Composite (CMC) control surfaces capable to withstand the harsh environment of re-entry combined with high temperature metallic components allowing the connection of the control surfaces to the cold structure. In particular, these support attachments have been designed as Ti6Al4V components and due to their geometrical complexity manufactured by using ALM technique.
