Wind Energy, Volume 29, Issue 6, June 2026.ABSTRACT Optimising turbine layouts to maximise power output is crucial for wind farm development, particularly in complex terrain where analytical wake models fail to capture key flow physics. We present the first application of Bayesian optimisation (BO) combined with large eddy simulations (LES) for utility‐scale wind farm layout optimisation in ...

Performance of an optimized rotor blade at off-design flight conditions [PDF]
An investigation is made of the dynamic and aerodynamic performance of a helicopter rotor previously optimized for minimum 4/rev vertical shear and blade weight subject to certain dynamic and structural constraints.

Exploration of Collagen as Binder for Aqueous Zinc Batteries and Symmetric Carbon Supercapacitors
ChemElectroChem, Volume 13, Issue 9, 5 May 2026.Aqueous dispersions of native collagen were successfully explored as “green” binders in oxide cathodes for zinc batteries and in carbon electrodes for aqueous double‐layer supercapacitors. Rechargeable water‐based metal batteries attract great attention due to low cost, high safety merits, sustainable cell fabrication and an easier recyclability at the

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis
International Journal of Chemical Kinetics, Volume 58, Issue 5, Page 199-209, May 2026.ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading
Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

An experimental study of the sensitivity of helicopter rotor blade tracking to root pitch adjustment in hover [PDF]
The sensitivity of blade tracking in hover to variations in root pitch was examined for two rotor configurations. Tests were conducted using a four bladed articulated rotor mounted on the NASA-Army aeroelastic rotor experimental system (ARES).
