About this document
JT8D Aircraft Noise Reduction Study by Nasrin Hosseini is a document available to read on EtoBox.
The NASA Refan Program aims to significantly reduce noise levels of existing JT8D powered aircraft by retrofitting them with quieter engines and acoustically treated nacelles. The program has demonstrated technical feasibility, achieving noise reductions of 7-12 EPNdB, which is below current noise standards. Production retrofit kits are projected to be available by 1976 for the DC-9 and 1977 for the B727, with minimal impact on aircraft performance.
