Modern helicopters employ swept, dihedral blade-tip and nonlinear twist to enhance its aerodynamic performance, which also increase manufacturing complexity and induce significant vibratory loads, and thus vibration reduction of NTBT (New Type Blade-Tip) rotors has become a key research focus. Due to the excellent compatibility and quick response, the TEF (Trailing Edge Flap) technology is promising for rotor vibration reduction. Nevertheless, most aeroelastic researches have been focused on TEF technology or NTBT rotor, respectively, the combinations of TEF/NTBT rotor system remain hardly explored. The CFD/CSD (Computational Fluid Dynamics/Computational Structural Dynamics) method is competent to meet this challenge, which can effectively consider the unconventional blade platforms, unsteady flowfields, and structural dynamics. Therefore, the present aeroelastic study on TEF/NTBT rotor based on CFD/CSD method holds significant theoretical value and engineering importance.

Xinting Yu, assistant professor in the Department of Physics and Astronomy at The University of Texas at San Antonio, is one of two recipients of the 2025 Harold C. Urey Prize.

The national award from the American Astronomical Society’s Division for Planetary Sciences recognizes early-career scientists shaping the future of space research.

Yu was honored for her research in planetary and exoplanetary science — the study of planets in our solar system and beyond. Her work focuses on how planetary surfaces and atmospheres interact and evolve.
