Active Control of Flapping Wings Using Wing Deformation
Transactions of the Japan Society for Aeronautical and Space Sciences, 2009 A new method for the attitude control of a flapping-wing aircraft is proposed. In this method, the variations in wing deformation, that is, the feathering angle and the camber, are controlled by pulling the wing at a certain point with a thread connected to a servomotor.

Bio-inspired flapping wing robots with foldable or deformable wings: a review
Bioinspiration & Biomimetics, 2022Abstract Traditional flapping-wing robots (FWRs) obtain lift and thrust by relying on the passive deformation of their wings which cannot actively fold or deform. In contrast, flying creatures such as birds, bats, and insects can maneuver agilely through active folding or deforming their wings.

Journal of Invertebrate Pathology, 2010
Deformed wing virus (DWV; Iflaviridae) is one of many viruses infecting honeybees and one of the most heavily investigated due to its close association with honeybee colony collapse induced by Varroadestructor. In the absence of V.destructor DWV infection does not result in visible symptoms or any apparent negative impact on host fitness.

Dragonfly wing nodus: A one-way hinge contributing to the asymmetric wing deformation
Acta Biomaterialia, 2017Dragonfly wings are highly specialized locomotor systems, which are formed by a combination of several structural components. The wing components, also known as structural elements, are responsible for the various aspects of the wing functionality. Considering the complex interactions between the wing components, modelling of the wings as a whole is ...

In-Flight Wing Deformation Measurement
51st AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2013This study has been conducting research on in-flight measurement for deformation of main wing of an aircraft. In this paper, a measurement method which optically measures the deformation of the main wing using high-resolution cameras is discussed. It also discusses a measurement system and a camera calibration.

Analysis of wing flexure deformation based on ANSYS
2018 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2018To explore the mechanical effects of the wing subjected to the aerodynamic loads and turbulence during the flight, this paper presents a finite element analysis of wing flexure deformation. Firstly, a large-aspect-ratio wing model is established. Taking material characteristics, wing structure and design principle into account, the assembly wing model ...

Deformed Wing Virus in Honeybees and Other Insects
Annual Review of Virology, 2019Deformed wing virus (DWV) has become the most well-known, widespread, and intensively studied insect pathogen in the world. Although DWV was previously present in honeybee populations, the arrival and global spread of a new vector, the ectoparasitic mite Varroa destructor, has dramatically altered DWV epidemiology.
