Hovering hummingbird wing aerodynamics during the annual cycle. I. Complete wing
The diverse hummingbird family (Trochilidae) has unique adaptations for nectarivory, among which is the ability to sustain hover-feeding. As hummingbirds mainly feed while hovering, it is crucial to maintain this ability throughout the annual cycle-especially during flight-feather moult, in which wing area is reduced. To quantify the aerodynamic characteristics and flow mechanisms of a hummingb...
متن کاملHovering hummingbird wing aerodynamics during the annual cycle. II. Implications of wing feather moult
Birds usually moult their feathers in a particular sequence which may incur aerodynamic, physiological and behavioural implications. Among birds, hummingbirds are unique species in their sustained hovering flight. Because hummingbirds frequently hover-feed, they must maintain sufficiently high flight capacities even when moulting their flight feathers. A hummingbird wing consists of 10 primary ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Passive Wing Rotation in Flexible Flapping Wing Aerodynamics
Insect wings are flexible. For rigid wings lift enhancing unsteady aerodynamics mechanisms, such as delayed stall via leading-edge vortices (LEVs), wake-capture, and rotational forces, characterize the lift generation of a hovering insect. We have uncovered a novel mechanism that fruit fly size insects can utilize to further increase the lift by adjusting its wing shape passively: A pair of a L...
متن کاملFlight in slow motion: aerodynamics of the pterosaur wing.
The flight of pterosaurs and the extreme sizes of some taxa have long perplexed evolutionary biologists. Past reconstructions of flight capability were handicapped by the available aerodynamic data, which was unrepresentative of possible pterosaur wing profiles. I report wind tunnel tests on a range of possible pterosaur wing sections and quantify the likely performance for the first time. Thes...
