Project description
New computational fluid dynamics methods make aircraft quieter
More than 4 million people in the EU are exposed to aviation noise levels of more than 55 decibels (dB) Lden from air transport while noise levels above 45 dB Lden are associated with adverse health effects. And yet, the sound of aircraft engines, can exceed 140 dB during take-off. To reduce this level, the EU-funded DJINN project will develop a new generation of reliable computational fluid dynamics (CFD) methods to assess promising noise-reduction technologies for future integrated propulsion aircraft. It is suggested to achieve 5 dB reduction of the jet-airframe interaction noise peak level at low frequencies. According to DJINN, understanding, modelling and predicting jet-airframe noise is the key to conceiving efficient noise-reduction technologies.
