Affordable Blisks (SAM 2 P3)

The main aim of the Affordable Blisk project was to develop technologies to significantly reduce manufacturing lead time and cost for these complex aerospace components.  A blisk (bladed disc) is created as single part by the joining of a blade to a disc using solid state joining techniques, enabling substantial weight and performance benefits, when compared to conventional disc/blades arrangements.

In addition, the project aimed to develop a Titanium Metal Matrix Composite (TiMMC) process to coat “ceramic fibres” with a metallic sheath, followed by winding and assembly. This technology enables a significant improvement in the strength and stiffness of components, while reducing their weight. The project improved process capability and automation, to drive down product cost, which will enable wider use of the technology across Rolls-Royce products and the wider supply chain.

A collaboration between Rolls-Royce, the AMRC and the MTC supported the aim of this project to reduce the manufacturing cycle times by 30%.  This reduction in cost helps to ensure these new technologies are available for civil applications, supporting future engine designs and confirming our competitiveness in this market.
