AnalySwift, LLC, a provider of efficient high-fidelity modeling software for composites, announced Seoul National University is leveraging its VABS software in the design and analysis work on its Seoul National University Flap (SNUF) Blade.
“The university joined AnalySwift’s Academic Partner Program in 2019 and we are excited to follow the work being done on composite rotor blades and similar structures,” said Allan Wood, president and CEO of AnalySwift. “The Academic Partner Program offers participating universities no-cost licenses of engineering software programs VABS and SwiftComp so students, researchers, and faculty can leverage the tools in their academic research.”
“In our Active Aeroelasticity and Rotorcraft Lab (AARL) at Seoul National University, coupled analysis using computational structural dynamics (CSD) and computational fluid dynamics (CFD) is being conducted to verify for analysis-experiment correlations to solve aeroelastic problems,” said Dr. SangJoon Shin, Professor of Aerospace Engineering. “For example, rotorcraft aeroelastic analysis, CSD/CFD coupled analysis, multidisciplinary design optimization of the active rotor blade such as active trailing edge flaps are being studied. Further, we study fixed aircraft flutter analysis for unmanned vehicles, as well as structural analysis for high speed vehicles, launch vehicles, and flexible structures for the bio-inspired flapping-wing micro air vehicle.”
One of AARL’s projects is an experimental evaluation on a mach-scaled SNUF blade for active vibration control. The research group uses VABS along with other tools for its structural analysis and design verification, including calculating 2D cross-sectional analysis properties.
