Computational aero-acoustics for fan duct propagation and radiation. Current status and application to turbofan liner optimisation
Significance of output:
Community Noise impact is critical in the design of modern aero-engines. Advanced Computational Aero-Acoustics (CAA) methods are combined with state-of- the-art optimisation to design acoustically absorbent liners to reduce noise from aero-engine intake ducts. The work stems from two Rolls-Royce sponsored Engineering doctorate programmes. It has contributed directly to improved noise engineering within Rolls-Royce and to better noise treatments for Rolls-Royce aero-engines. One of the methods presented is incorporated in the in-house Rolls-Royce liner optimisation code ‘VU20’ and has contributed to the design of optimal liners for Trent-1000, Trent-XWB and BR725 engines (contact: Dr Andrew Kempton, Chief Noise Specialist, Rolls-Royce)
