| Popis: |
Aircraft exterior noise reduction is a major task for manufacturer and carrier. However, optimum sound absorption over a broad frequency range at engine level is still a challenging aspect for acoustic liner. This paper presents the special acoustic absorber concept as broadband working liner with limited space needed. Experimental as well as numerical work is presented for different applications as there are hot stream liner for exhaust integration, broadband liner for bypass integration and low frequency broadband liner for integration into a shrouded fan. |
