RR’s Composite Fan Passes Crosswind Test

Rolls-Royce’s new composite carbon/titanium (CTi) fan for its Advance and UltraFan Trent engines has successfully completed crosswind flight condition testing

Rolls-Royce’s new composite carbon/titanium (CTi) fan for its Advance and UltraFan Trent engines has successfully completed crosswind flight condition testing.

The CTi fan was installed on a Trent 1000 ALPS (advanced low-pressure system) engine and tested at Rolls-Royce’s test facility in Mississippi.

Mark Thomas, Rolls-Royce’s chief engineer for technology and future programmes, civil large engines, confirmed that the programme will now move on to the next phase of demonstration, including flight testing.

According to Rolls-Royce, the CTi blade will offer a 1,500lb weight saving per aircraft and its Advance and UltraFan engine designs will cut fuel burn by 20-25 per cent compared with first generation Trent engines.

The OEM says its Advance engine system could be operational from 2020 and the UltraFan from 2025.
