“…Even though several researchers (Ganguli et al, 2010; Mengesha et al, 2011; Combes and Daniel, 2003) have investigated bending properties of insect wing materials, these previous studies are not exhaustive or thoroughly convincing. Therefore, the inherent causes of the bending features of insect wings still require investigation.…”

In this study, the spanwise and chordwise bending stiffness EI of honeybee forewings were measured by a cantilevered bending test. The test results indicate that the spanwise EI of the forewing is two orders of magnitude larger than the chordwise EI. Three structural aspects result in this span-chordwise bending anisotropy: the distribution of resilin patches, the corrugation along the span and the leading edge vein of the venation. It was found that flexion lines formed by resilin patches revealed through fluorescence microscopy promoted the chordwise bending of the forewing during flapping flight. Furthermore, the corrugation of the wing and leading edge veins of the venation, revealed by micro-computed tomography, determines the relatively greater spanwise EI of the forewing. The span-chordwise anisotropy exerts positive structural and aerodynamic influences on the wing. In summary, this study potentially assists researchers in understanding the bending characteristics of insect wings and might be an important reference for the design and manufacture of bio-inspired wings for flapping micro aerial vehicles.

“…The wing stiffness distribution is complicated because the wing is a passive structure mainly composed of veins and membranes (Wootton, 1992) and with no internal muscles inside (Mengesha et al, 2011). Although several researches focusing on measuring flexural stiffness distribution of insect wing have been done (Combes and Daniel, 2003; Ganguli et al, 2010; Lehmann et al, 2011; Mengesha et al, 2011), the wing is simplified as a one-dimensional beam in these researches, thus the spatial flexural stiffness distribution was not measured precisely. To acquire fine spatial flexural stiffness distribution requires an accurate deformation measurement first.…”

Summary StatementA fine shape and deformation field measurement of insect wing is achieved by a self-developed setup. This measurement could foster investigation of insect wing stiffness distribution.AbstractFor measuring the shape and deformation of insect wing, a scanning setup adopting line laser and coaxial LED light is developed. Wing shape can be directly acquired from the line laser images by triangulation. Yet the wing deformation field can also be obtained by a self-devised algorithm that processes the images from line laser and coaxial LED simultaneously. During the experiment, three wing samples from termite and mosquito under concentrated force are scanned. The venation and corrugation could be significantly identified from shape measurement result. The deformation field is sufficiently accurate to demonstrate its variation from wing base to tip. The load conditions in experiments are also be discussed. For softer wings, local deformation is apparent if pinhead is employed to impose force. The similarity analysis is better than 5% deformation ratio as a static criterion, if the wing is simplified as a cantilever beam. The setup is proved to be effective and versatile. The shape and deformation fields would give enough details for the measurement of wing stiffness distribution.

“…The wings must have adequate stiffness and hardness to bear the various types of loads demanded by flight, such as flapping, glide flight, and circles during flying [2] . These relatively thin and light wings are more suitable for flapping flight because they have better aerodynamic performance and require less inertial power [1,3] . Stability is obtained with minimal material, similarly to corrugated lightweight structures [4,5] .…”

“…Studies related to the structural parameters involving insect wing microstructure that affects the wing's aerodynamic properties form an important part of investigation [1,8,[9][10][11][12] . For example, there are a number of key structures in the wing which contribute to the manner in which it bends in flight and therefore help facilitate the wing's aerodynamic properties [3,13] . Hence, it is critically important to study the microstructure in detail that can give new insights into the insect wing's aerodymanics.…”

Mimicking insect flights were used to design and develop new engineering materials. Although extensive research was done to study various aspects of flying insects. Because the detailed mechanics and underlying principles involved in insect flights remain largely unknown. A systematic study was carried on insect flights by using a combination of several advanced techniques to develop new models for the simulation and analysis of the wing membrane and veins of three types of insect wings, namely dragonfly (Pantala flavescens Fabricius), honeybee (Apis cerana cerana Fabricius) and fly (Sarcophaga carnaria Linnaeus). In order to gain insights into the flight mechanics of insects, reverse engineering methods were used to establish three-dimensional geometrical models of the membranous wings, so we can make a comparative analysis. Then nano-mechanical test of the three insect wing membranes was performed to provide experimental parameter values for mechanical models in terms of nano-hardness and elastic modulus. Finally, a computational model was established by using the finite element analysis (ANSYS) to analyze and compare the wings under a variety of simplified load regimes that are concentrated force, uniform line-load and a torque. This work opened up the possibility towards developing an engineering basis for the biomimetic design of thin solid films and 2D advanced engineering composite materials.
