Simulated pilot-in-the-loop testing of handling qualities of the flexible wing aircraft
Aviation, 2020 This article aims to indicate the differences between rigid and flexible wing aircraft flying (FQ) and handling (HQ) qualities. The Simulation Framework for Flexible Aircraft was used to provide a generic cockpit environment and a piloted mathematical ...

Virtual Sensing of Wind Turbine Loads With Multi‐Hidden Markov Models for Above‐Rated Wind Speeds
Wind Energy, Volume 28, Issue 12, December 2025.ABSTRACT The growing demand for wind energy necessitates efficient health monitoring strategies to ensure the long‐term reliability of wind turbines. Monitoring critical loads, such as flapwise blade root moments and tower base fore‐aft moments, is crucial for preventing turbine fatigue and failure. However, direct measurements through physical sensors

Accelerating Vortex Particle Methods by Downsampling the Vorticity Field Representation
International Journal for Numerical Methods in Fluids, Volume 97, Issue 11, Page 1410-1425, November 2025.This paper presents two downsampling algorithms for vortex particle methods (VPMs) that reduce the number of computational elements representing the vorticity field. The two methods demonstrate significant reductions in particle count and computation time in benchmark cases at a cost of diffusive errors.

Wind Energy, Volume 28, Issue 11, November 2025.ABSTRACT Computationally efficient frequency‐domain models can play a very important role in facilitating conceptual design optimization of floating wind turbines (FWTs). However, achieving sufficient accuracy in such models is challenging due to the nonlinear variation of the aerodynamic loads, particularly the interaction between the floating ...

Dynamic Stall Characteristics of Thick Wind Turbine Airfoils
Wind Energy, Volume 28, Issue 11, November 2025.ABSTRACT This paper studies the dynamic stall characteristics of thick flatback and nonflatback wind turbine airfoils. Two airfoils with a maximum thickness of 35%$$ 35\% $$ were studied, with trailing edge thicknesses of 2%$$ 2\% $$ and 10%$$ 10\% $$, respectively.

Aeroelastic Characteristics of Rotor Blades of Last Stage of a Powerful Steam Turbine
Journal of Mechanical Engineering, 2023 Blades of powerful steam turbines are subjected to significant unsteady loads, which, in some cases, can lead to the appearance of self-excited oscillations or auto-oscillations.

Divergence‐Free Correction for Synthetic Wind Fields
Wind Energy, Volume 28, Issue 11, November 2025.ABSTRACT Synthetic wind fields generated for wind turbine simulations do not satisfy incompressibility condition, thus, are not divergence‐free. This results in spurious pressure fluctuations when input as a boundary condition to, for example, incompressible large eddy simulations (LES).

The Effect of Rotor Size on the Teeter Behavior of Two‐Bladed Wind Turbines
Wind Energy, Volume 28, Issue 11, November 2025.ABSTRACT The rotor of a two‐bladed turbine allows the implementation of an additional degree of freedom around the rotating hub y‐axis. This idea is over 60 years old, and various research and commercial turbines have had a teeter hinge. Fatigue and extreme loads can be reduced significantly with a teeter hinge. Teetered turbines have been mainly below
