Investigation of the Influence of Different Flapping Wing Motion Characteristics on Aerodynamic Parameters under Incoming Flow [PDF]
Journal of Applied Fluid MechanicsThere is high flight efficiency of flapping wing aircraft, and its hovering ability, wind loading rating, maneuverability and concealment are better than that of multi-rotor and fixed-wing aircraft. In this paper, the bionic flapping wing is taken as the

Zoo Biology, EarlyView.Birds involved in bird shows were compared against non‐show birds regarding show paticipation, behaviour, body score condiiton, and feather condition. Additionally, comparisons between on and off show days as well as before and after the show were made to investigate differences in behaviour and condition. Show birds demonstrated a closer to ideal body

Dynamic response of a piezoelectric flapping wing
, 2015 Piezo-composite membranes have advantages over motorized flapping where frequencies are high and certain coupling between bending and twisting is useful to generate lift and forward flight. We draw examples of fruit fly and bumble bee.

Four-Winged Flapping Flyer in Forward Flight [PDF]
, 2015 We study experimentally a four-winged flapping flyer with chord-wise flexible wings in a self-propelled setup. For a given physical configuration of the flyer (i.e. fixed distance between the forewing and hindwing pairs and fixed wing flexibility), we explore the kinematic parameter space constituted by the flapping frequency and the forewing-hindwing ...

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior
Integrative Zoology, EarlyView.Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Geolocation with a magnetic sensor
Methods in Ecology and Evolution, EarlyView.Abstract Many migratory animals use spatial variation in the Earth's magnetic field for orientation and navigation. This raises the possibility of exploiting these same cues to geolocate and track migratory animals throughout their annual journeys. Magnetic‐based geolocation could be particularly valuable for small aerial and aquatic species, for which
