Aerodynamic forces in deformed wings.

2023
In this work, we carry out a detailed study of the change in aerodynamic forces due to wing deformation in flight. The results presented are for a wing model of a fixed semi aspect ratio sAR = 4, and different chord-based Reynolds numbers in the range of application of UAVs. Our results show that numerical simulations with turbulence models are able to

Flapping Wing Force and Deformation Analysis

53rd AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference<BR>20th AIAA/ASME/AHS Adaptive Structures Conference<BR>14th AIAA, 2012
Research into the flight of miniature aerial vehicles (MAV) is still uncovering the basic aeroelastic interactions involved in flight at this scale. The complex relationships between structure and fluid are driven by vortex shedding and pushing air, rather than traditional aerodynamics.

Solenopsis richteri (Hymenoptera: Formicidae) alates infected with deformed wing virus display wing deformity with altered mobility

The Science of Nature
Deformed wing virus (DWV) has long been identified as a critical pathogen affecting honeybees, contributing to colony losses through wing deformities, neurological impairments, and reduced lifespan. Since DWV also affects other pollinators, it poses a significant threat to global pollination networks.

Detection of Deformed wing virus, a honey bee viral pathogen, in bumble bees (Bombus terrestris and Bombus pascuorum) with wing deformities

Journal of Invertebrate Pathology, 2006
Honey bees (Apis mellifera) productively infected with Deformed wing virus (DWV) through Varroa destructor (V. destructor) during pupal stages develop into adults showing wing and other morphological deformities. Here, we report for the first time the occurrence of bumble bees (Bombus terrestris, Bombus pascuorum) exhibiting wing deformities resembling

Dynamic grid deformation using Navier-displacement equation for deforming wings

9th Computational Fluid Dynamics Conference, 1989
For dynamic and aeroelastic applications of maneuvering wings, the solid boundaries undergo rigid-body motion and aeroelastic deformation. For rigid-body motion, the conservative fluid dynamics equation, in terms of the Eulerian description, is written in terms of a moving frame of reference, and the problem is solved on a time-independent body ...

Research on Measurement and Deformation of Flexible Wing Flapping Parameters

2019
In order to study the flexible deformation process of the micro flapping wing during its fluttering, the dynamic three-dimensional reconstruction of the wings is carried out by the RealSense SR300 depth camera. The wing flapping parameters is measured and the deformation of different wings flapping are analyzed.

Large deformation study of a wing

2018
Wing loading test is one of the most important milestones a manufacturer has to pass during the aircraft certification process. In this context, finite element simulations can arise as an excellent tool to reduce time in design processes prior to test, as well as to serve on posteriori analysis.

Recalibration of a stereoscopic camera system for in-flight wing deformation measurements

Measurement Science and Technology, 2016
The applicability of wing deformation measurements techniques based on stereoscopic photogrammetry has already been demonstrated for in-flight applications. The position and alignment of a stereoscopic camera setup is described in the external parameters of the camera calibration by a rotation matrix and a translation vector.
