Abstract Scope |
Acoustic liners are integral to the noise management of aircraft engines; however, advanced liner concepts are needed to address the acoustic requirements of novel engine layouts. Perforate sheet over honeycomb core, or single degree of freedom (SDOF), liners are the traditional system that has been used in the past, while more advanced double degree of freedom (DDOF) liners are the state-of-the-art liners currently implemented in aircraft engines. Leveraging the design freedom of additive manufacturing, our current research explores the use of TPMS lattice structures as advanced core structures for acoustic liners. In this study, previously developed design exploration methods have been implemented to compare the performance of novel TPMS acoustic liners with the SDOF and DDOF liners. Computational and analytical results are verified through fabrication and experimental testing. Performance comparison between the acoustic liner types would show us the viability of the TPMS lattice liner for future refinement. |
