The add-on acoustic black hole (AABH), as a vibration reduction device with light weight, rich modal density, and high damping characteristics, has been extensively studied in the vibro-acoustic control of structures. However, there has been no research on application of AABH in the control of the typically aeroelastic instability phenomenon of a panel in supersonic flow. Meanwhile, the prediction of aerodynamic response and flutter boundary of panel structures with attached AABH presents a complex challenge, requiring a sophisticated numerical strategy. Therefore, establishment of a numerical method for coupled aeroelastic analysis of a panel in supersonic flow with AABH and the performance of AABH in suppression of the panel's aeroelastic instability is of great significance.The add-on acoustic black hole (AABH), as a vibration reduction device with light weight, rich modal density, and high damping characteristics, has been extensively studied in the vibro-acoustic control of structures.

Animals are not just inhabitants of the natural world—they are its architects. A new study led by Professor Gemma Harvey from Queen Mary University of London has revealed how hundreds of species shape the landscapes we depend on, from vast termite mounds visible from space to hippos carving drainage systems and beavers creating entire wetlands.

Research team led by Limin Xiao revolutionizes metadata management in distributed file systems with a novel consistency framework that reduces synchronization delay and enhances scalability, outperforming existing methods in global virtual data space file systems.

As more satellites, telescopes, and other spacecraft are built to be repairable, it will take reliable trajectories for service spacecraft to reach them safely. Researchers in the Department of Aerospace Engineering in The Grainger College of Engineering, University of Illinois Urbana-Champaign are developing a methodology that will allow multiple CubeSats to act as servicing agents to assemble or repair a space telescope. Their method minimizes fuel consumption, guarantees that servicing agents never come closer to each other than 5 meters, and can be used to solve pathway guidance problems that aren’t space related.
