Morphing Wing Droop Nose with Large Deformation: Ground Tests and Lessons Learned

open access: yesAerospace, 2019
A design for a new high lift system that features a morphing wing leading edge “droop nose” has the potential to generate high lift coefficients whilst mitigating airframe noise emissions.

Performance Improvement of Variable Speed Rotors by Gurney Flaps [PDF]

open access: yes, 2017
Gurney flaps are used for improving the performance of variable speed rotors. An analytical model able to predict helicopter rotor power is first presented, and the flight data of the UH-60A helicopter is used for validation. The predictions of the rotor

From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 2, February 2026.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Experimental and Numerical Analysis of the Aerodynamic Characteristics of the Flexing Wing With Active Camber Design

open access: yesInternational Journal of Aerospace Engineering
The flexing/morphing concept is a means of improving wings’ aerodynamic performance. Morphing technology such as the fishbone active camber (FishBAC) design has demonstrated drag reduction of over 30% at moderate angles of attack (AoAs) and 40% at higher

Trade-Off Conceptual Design of a Camber Morphing Flap for the Next Generation Hybrid Electrical Aircraft Across the HERWINGT Project

open access: yesApplied Sciences
Compliant wing morphing devices deal with controlled and smooth adaptation of the subcomponents’ shape to external conditions. Their structural stiffness distribution, typically resulting from an optimization design process, is tailored to ensure large ...

Trailing-edge dynamics and morphing of a deformable flat plate at high Reynolds number by time-resolved PIV [PDF]

open access: yes, 2014
The present paper investigates the turbulent wake structure in the near-region past the trailing edge of a deformable inclined plate. The plate is actuated by shape memory alloys. Using these actuators a significant deformation (bending) can be achieved (

Modelling and analysis of aeroelastic tailoring blade wind turbine systems [PDF]

open access: yes, 2017
Modelling and performance analysis of wind turbine control systems with aeroelastic tailoring blades (ATBs) are investigated. An industrial scale horizontal axis wind turbine (HAWT) model with rigid blades is firstly developed as the baseline model using

Building a Bird: Musculoskeletal Modeling and Simulation of Wing-Assisted Incline Running during Avian Ontogeny [PDF]

open access: yes, 2018
Flapping flight is the most power-demanding mode of locomotion, associated with a suite of anatomical specializations in extant adult birds. In contrast, many developing birds use their forelimbs to negotiate environments long before acquiring “flight ...
