Abstract

The design of future low-noise aircraft will require an account of noise shielding as a fundamental design parameter. This aspect was already recognized in the seventies, where early experimental work set the ground on possible solutions to the conventional, short and reduced take-off and landing noise problem. The current low-noise aircraft design concepts of the hybrid-wing-body type require establishing a new knowledge base to allow an assessment of its potential noise benefit. Experimental work done in the course of the last 15 years slowly moved in this direction with the establishment of new testing methodologies. Currently available databases render an estimation of the turbomachinery noise shieding benefit of specific design choices on aircraft of the hybrid-wing- body type possible. Still, research in this domain would strongly benefit from the development of reliable and flexible numerical prediction methods. A broadband non-intrusive laser-based sound source is used to perform experiments on a wide range of configurations, providing an extensive high-quality validation database. The paper presents an overview of available datasets from dedicated experimental investigations, ranging from simple generic test cases to full 3D aircraft configurations, as well as comparisons with numerical results.
