Influence of Bimodal Pore Architecture on Broadband Acoustic Absorption and Mass Reduction in AlSi Open-Cell Structures

Lightweight materials capable of simultaneously providing noise and mass reduction are increasingly required in aerospace applications. This paper investigates the acoustic performance of a novel hierarchical bimodal architecture in open-cell AlSi porous structures, integrating μ...

Static Ground Validation of an AI-Assisted Acoustic Target Detection and Azimuth Estimation Framework on a Flying-Wing VTOL UAV

Autonomous acoustic sensing systems are increasingly investigated for unmanned aerial vehicle (UAV)-based surveillance and environmental monitoring applications due to their passive operation and relatively low computational requirements. However, the integration of acoustic clas...
