SAGE 4 – Geared Turbofan
SAGE 4, the purpose of the advanced Geared Turbofan (GTF) Engine Demonstrator as an important part of SAGE platform is to further improve relevant technologies in order to significantly reduce fuel burn in combination with additional improvements in noise emission to achieve comfortablemargins to expected ICAO Chapter 5 noise limits. The GTF architecture allows integration into existing aircrafts without extensive integration effort. Finalisation of the Concept optimization phase, with a detailed review of all technologies to be inserted in the demonstrator has been completed in Q4 2012releasing the detail design phase of the program. SAGE 4 ground test demonstration is scheduled to start in March 2015.
