Lift production in the hovering hummingbird.
Aerodynamic theory and empirical observations of animals flying at similar Reynolds numbers (Re) predict that airflow over hummingbird wings will be dominated by a stable, attached leading edge vortex (LEV). In insects exhibiting similar kinematics, when the translational movement of the wing ceases (as at the end of the downstroke), the LEV is shed and lift production decreases until the energ...
متن کاملSurge-yaw Control of a Hybrid Underwater Robotic Vehicle
An underwater robotic vehicle is being developed at the UFABC (Universidade Federal do ABC) which has as main mission the inspection of ship hull thickness using ultrasonic transducers. This is a hybrid ROV (Remotely Operated Vehicle) due to its extreme locomotion capabilities adapted of the terrain tracked vehicles. This paper presents the surgeyaw control system of a new hybrid underwater veh...
متن کاملHummingbird hovering energetics during moult of primary flight feathers.
How does a hovering hummingbird compensate for the loss of flight feathers during moult when the mechanism of lift force generation by flapping wings is impaired? The flight performance of five individual ruby-throated hummingbirds with moulting primary flight feathers and reduced wing area was compared with that before their moult. Hummingbirds were flown in reduced air densities using normoxi...
متن کاملQuantifying the dynamic wing morphing of hovering hummingbird
Animal wings are lightweight and flexible; hence, during flapping flight their shapes change. It has been known that such dynamic wing morphing reduces aerodynamic cost in insects, but the consequences in vertebrate flyers, particularly birds, are not well understood. We have developed a method to reconstruct a three-dimensional wing model of a bird from the wing outline and the feather shafts ...
متن کاملChromatic Signals Control Proboscis Movements during Hovering Flight in the Hummingbird Hawkmoth Macroglossum stellatarum
Most visual systems are more sensitive to luminance than to colour signals. Animals resolve finer spatial detail and temporal changes through achromatic signals than through chromatic ones. Probably, this explains that detection of small, distant, or moving objects is typically mediated through achromatic signals. Macroglossum stellatarum are fast flying nectarivorous hawkmoths that inspect flo...
