Abstract

Aircraft exterior noise is typically reduced by optimizing an isolated aircraft component. The noise emission of this component is optimized with high-fidelity tools or wind tunnel measurements. However, if installed on-board of the aircraft the optimization may not have the desired effect on the total noise impact due to propagation effects or the interaction with other components. Hence, a method is presented, that derives noise reduction requirements for aircraft components based on the total aircraft noise impact. The method is implemented in a parametric aircraft noise prediction tool and applied to a reference aircraft. The aim is to use the noise requirements within conceptual aircraft design to obtain low-noise aircraft in a target-oriented way. Ultimately, this may be a first step towards a noise-to-design process.
