Project description
Damping noise in ultra-high bypass ratio engines
The bypass ratio is one of the key indicators of turbofan engine efficiency. Ultra-high bypass ratio (UHBR) engines have large fans that rotate at relatively low speeds and therefore consume less fuel. Although high bypass ratios generate lower jet and fan noise, the engine core noise increases. The EU-funded CIRRUS project will combine numerical simulations and experimental work to reduce engine core noise for future UHBR 2030+ turbofan engines. Another part of the work will be geared towards the development of acoustic liners based on ceramic matrix composites. The proposed low-noise concepts will be tested in real engines. The experimental measurements will be compared to theoretical ones to bring the proposed technologies to a high level of maturity (technology readiness level 6).
