Pasquini, U.S. Naval Research Laboratory Corporate Communications WASHINGTON, – Nicole Xu, Ph.D., a U.S. Naval Research Laboratory (NRL) Postdoctoral Research Associate from the Laboratories for Computational Physics & Fluid Dynamics designs faster and more energy efficient underwater vehicles using bioinspired shark skin-like surfaces. ....
VIRIN: 210310-N-NO204-020 Nicole Xu, Ph.D., a U.S. Naval Research Laboratory (NRL) Postdoctoral Research Associate from the Laboratories for Computational Physics & Fluid Dynamics designs faster and more energy efficient underwater vehicles using bioinspired shark skin-like surfaces. “Shark skin comprises arrays of teeth-like denticle structures, which contribute to fast and stealthy swimming by turbulent drag reduction,” Xu said. She began her NRL postdoctoral associateship in January 2021. “Xu has demonstrated extraordinary motivation and initiative, as well as technical expertise in the area of unpiloted systems research,” said Jason Geder, an NRL aerospace engineer who is Xu’s mentor. Xu’s goal is to test these bioinspired surfaces on hydrofoils in flow channels before implementing the skins onto unpiloted underwater vehicles (UUV), such as the NRL-developed WANDA UUV and other traditional underwater vehicles. ....

WASHINGTON A team of researchers from the U.S. Naval Research Laboratory (NRL) received a United States and United Kingdom Science and Technology Cooperation Commendation from the Office of the Under Secretary of Defense for Research and Engineering, Dec. 4. The NRL team of experts with the Bio-inspired Adapted Techniques for Sensing, Actuation and Vocalization using Vibro-acoustics (BATSAVVi) program were commended for establishing bilateral collaboration between the U.S. Navy, U.S. Air Force Research Laboratory, and Defence Science and Technology Laboratory. The NRL team, led by Don Sofge and Jason Geder, along with Joseph Lingevitch, Ph.D., Matthew Kelly, Daniel Lofaro, Ph.D., Loy McGuire, and Luke Calkins addressed research challenges in small, unmanned vehicle navigation and communication. They successfully proved novel, bio-inspired acoustic approaches to obstacle detection and avoidance within the program. ....
