Safran: Open Fan tested in wind tunnel with ONERA
The aim of the ECOENGInE tests is to demonstrate the aerodynamic and acoustic performance of the fan module in a simulated flight environment, and to validate the design of the fan blades.
According to Safran, the Open Fan could ultimately reduce fuel consumption and CO2 emissions by 20% - up to 80% with the incorporation of sustainable fuels - on the next generation of single-aisle aircraft by 2035.
To support the maturity of the OpenFan's aerodynamics and acoustics, Safran Aircraft Engines and ONERA recently signed a framework agreement to secure an ambitious test plan from 2024 to 2028, following on from the ECOENGInE tests already carried out.
