Dual Wall Turbine Technology Development (DualWallTurb)

The next generation of Large Civil turbofans will feature higher bypass ratios and LeanBurn Combustion

technology to improve propulsive efficiency and hence reduce fuel-burn, CO2 and NOx emissions. They are

likely to be driven by a geared LP system, as per the Rolls-Royce UltraFan™ engine concept. Key enablers for

this overall engine concept are hotter, smaller and durable core turbine technologies. DualWallTurb will

address this requirement by developing novel design and manufacturing technologies for high temperature

materials towards advanced levels of technology readiness (MCRL4/TRL4), thereby enabling a step change in

cooling flow reductions in the High Pressure Turbine (HPT). The project will achieve this by bringing together

existing and further advancing UK based know how on manufacturing, advanced design knowledge as well as

the UK based research infrastructure whilst focusing on the fastest possible technology delivery in support of

upcoming engine programmes. As a result a strategic key design and manufacturing capability will be

developed in the UK and secured for future exploitation in the UK.
