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

Aerodynamic and aeroacoustic characteristics of a bionic morphing flap

Energy Reports, 2023
Birds adapt to the changing flight conditions by performing intricate feather-movements to manipulate the airflow. The avian wings often undergo seamless transformations at the trailing-edge to achieve camber-reflexes for extended flight envelope.

Hybrid Auxetic Architectures: Integrating Curvature‐Driven Design for Enhanced Mechanical Tunability and Structural Performance

Advanced Engineering Materials, Volume 28, Issue 4, 18 February 2026.
Curvature‐tuned auxetic lattices are designed, fabricated, and mechanically characterized to reveal how geometric curvature governs stretchability, stress redistribution, and Poisson's ratio evolution. Photoelastic experiments visualize stress pathways, while hyperelastic simulations quantify deformation mechanics.
