The CIRRUS project aims to reduce core noise in future ultra-high bypass ratio turbofan engines. It focuses on developing advanced numerical and experimental methods to understand noise sources and to create new acoustic liners to minimize noise emissions.
The propulsion of the majority of commercial aircraft relies on turbofan engines.
The current trend for future turbofan engines is towards even higher bypass ratios.
These Ultra-High Bypass Ratio (UHBR) engines have large fans rotating at relatively low speeds.
As a consequence of the lower speed, the fuel consumption can be reduced.
Another consequence is that the engine noise signature is modified.
While jet noise and fan noise will be reduced, core noise will be become more significant.
