       In the Turbomachinery Cluster:
       • Design and off-design optimisation of highly loaded industrial gas turbine
           stages (DAIGTS)
           The objective is to improve turbine efficiency by 4%, to help move small-
           medium gas turbines into the 35% efficiency target
       • Development of innovative techniques for compressor aero-mechanical desi-
           gn (DITCAD)
           The project aims to enhance the characteristics of heavy-duty gas turbines
           by the introduction of advanced axial compressor designs.

       In the Materials Cluster:
       • CMC Integration and demonstration for gas turbine engines (CINDERS)
           The objective is to develop technology to allow use of CMC combustors with
           an internal wall temperature of 1450C
       • Advanced long life blade coatings (ALLBATROS)
           The aim is to increase the efficiency, reliability and maintainability of gas
           turbine blades and vanes by developing and evaluating new high-resistant
