Fog spontaneously folds mosquito wings
Physics of Fluids, 2015The flexibility of insect wings confers aerodynamic benefits, but can also present a hazard if exposed to fog or dew. Fog can cause water to accumulate on wings, bending them into tight taco shapes and rendering them useless for flight. In this combined experimental and theoretical study, we use high-speed video to film the spontaneous folding of ...

Although insects are winged animals there can be few species, if any, that spend more time in the air than on the ground. For convenience and protection it is imperative that their delicate membranes can be safely stowed away when not in use. Dragonflies are one of the few groups to rest with the wings fully outstretched, the others having a basal ...

The effect of folding on motion flapping wing aero vehicle
2017 IEEE International Conference on Multisensor Fusion and Integration for Intelligent Systems (MFI), 2017An interesting about MAV and a research for flapping wing aero vehicle has been increased. It is required that take-off and landing abilities to lift up a vehicle by flapping motion to achieve a special purpose for flapping wing aero vehicle. An airfoil has to generate lift force more than a weight of the body to work take-off from the ground without ...

Incorporation of Passive Wing Folding in Flapping Wing Miniature Air Vehicles
Volume 7: 33rd Mechanisms and Robotics Conference, Parts A and B, 2009Flapping wing motion produces positive lift in the down stroke and negative lift in the upstroke under zero forward velocity. Large birds frequently exhibit flight behavior where their wings are folded during the upstroke, thus lowering the air resistance as the wing is moved upwards. The result is reduced magnitude of negative lift produced during the

Investigation of dynamic characteristic of forward swept folding wing
2011 IEEE International Conference on Automation and Logistics (ICAL), 2011In order to investigate the dynamic characteristic of the aircraft with forward swept folding wing, the finite element model of the forward swept folding wing was modeled in the commercial finite element analysis software MSC Patran, and the corresponding modal analysis was performed using the SOL 103 solution sequence in the MSC Nastran.

Continuum Aeroelastic Model for a Folding-Wing Configuration
AIAA Journal, 2009An aeroelastic model and analytical solution methodology are developed to find the flutter solutions for the continuous representation of a two-segment uniform folding wing. The model is developed such that different parameters can be easily modified to examine changes in the flutter solutions.

Strange Wing Folding in a Rove Beetle
2019This chapter focuses on the strange wing folding in rove beetles and shows its interesting properties from the point of view of engineering applications. Compared with other typical beetles, the elytra of most rove beetles are reduced, and the projecting abdomen is exposed and freely movable.
