ROLLS-ROYCE AND Snecma are considering blade-in-ring technology as part of their collaborative Advanced Military Engine Technology (AMET) demonstrator project.

Blade-in-ring, or Bling, technology uses titanium metal matrix materials, and offers a substantial weight saving over more conventional materials.

As far as AMET is concerned, the two companies are considering using the titanium-based Bling for the compressors. The ring would replace the main disc, offering up to a 70% weight saving, according to officials working on the project.

The AMET programme is intended to explore potential combat-aircraft engine technologies for use on the next generation of combat aircraft beyond the Dassault Rafale and Eurofighter EF2000.

The titanium metal-matrix materials could also be used for engine shafts and control rods, offering additional weight savings over current designs.
