SUMMARY The flying fish (family Exocoetidae) is an exceptional marine flying vertebrate, utilizing the advantages of moving in two different media, i.e. swimming in water and flying in air. Despite some physical limitations by moving in both water and air, the flying fish has evolved to have good aerodynamic designs (such as the hypertrophied fins and cylindrical body with a ventrally flattened surface) for proficient gliding flight. Hence, the morphological and behavioral adaptations of flying…

Numerical prediction of aerodynamic performance for a flying fish during gliding flight.

A three-degrees-of-freedom (3-DOF) dynamic model in the longitudinal plane is built based on the aerodynamic coefficients obtained in the simulations, to predict its gliding performance, and it is proved to be longitudinally stable.

Lift and Drag Trend of Exocoetus Volitans Model in the Wind Tunnel

Flying fish is a fascinating animal that has the abilities to swim and glide. These unique abilities have attracted interest amongst scientist and researchers alike. Several studies have been

Take-off performance of flying fish Cypselurus heterurus doederleini measured with miniature acceleration data loggers

The results suggest that the flying fish in the study may have recognized the capacity of the experimental space and regulated swimming performance before leaping from the water surface, suggesting that the flight performance of flying fish may have been regulated.

Why does a flying fish taxi on sea surface before take-off? A hydrodynamic interpretation

From the direct comparison between the two locomotive modes, it is apparently evidenced that the flying fish can be further accelerated by taxiing along the water surface, although the power is significantly smaller than the swimming locomotion.

Combined effects of body posture and three-dimensional wing shape enable efficient gliding in flying lizards

Overall, it is empirically show that the aerodynamics of biological airfoils coupled with the animal’s ability to control posture and their 3D wing shape enable efficient gliding and adaptive flight control in the natural habitat.

A Computational Investigation on Aerodynamic Performance of the Cross-Section of a Flying Fish (Cypselurus Hiraii) in Comparison with Conventional Aerofoil Behaviour

Bio-mimicry is one of the leading fields of research that has been around since the early ages of science. Aerospace industry, especially, takes most of its design inspiration from the aquatic life.

How animals glide: from trajectory to morphology1

This review focuses on the physical aspect of how gliders produce and control their flight from takeoff to landing, and some species are unspecialized for gliding, producing aerodynamic forces using posture and orientation alone.

How animals glide: from trajectory to morphology

This review focuses on the physical aspects of how glide trajectories are produced, and additionally discusses the range of morphologies and postures that are used to control aerial movements across the broad diversity of animal gliders.

Swimming near the substrate: a simple robotic model of stingray locomotion

A simple, stingray-inspired physical model offers insights into ground effects on undulatory swimmers, contrasting the self-propelled swimming speed, power requirements, and hydrodynamics of fins swimming with fixed kinematics near and far from a solid boundary.

A biologically inspired, flapping-wing, hybrid aerial-aquatic microrobot

This work analyzes the dynamics of flapping locomotion in an aquatic environment, identifies the challenges and benefits of surface tension effects on microrobots, and further develops a suite of new mesoscale devices that culminate in a hybrid, aerial-aquaticmicrorobot.

Investigation of Aerodynamic Capabilities of Flying Fish in Gliding Flight

In the present study, we experimentally investigate the aerodynamic capabilities of flying fish. We consider four different flying fish models, which are darkedged-wing flying fishes stuffed in

Wing design and scaling of flying fish with regard to flight performance

Fin and body dimensions of six genera of flying fish were examined to study variation in morphological parameters in relation to aerodynamics performance and scaling relationships for wing loading and aspect ratio indicate that wing morphology in the Exocoetidae is more similar to birds and bats than to other gliders.

On the Structural Specilization of Flying Fishes from the Standpoint of Aerodynamics

It is evident that such superficially aeroplane-like insects as dragon flies are really not miniature planes at all, but are working on radically different principles in which the paired outstretched wings vibrate practically all through flight in such a manner that their tips describe a figure.

Flight in ground effect above a flat, smooth surface may give an animal considerable performance advantages, including a reduction in cost of transport of up to 15%, and a reduction in mechanical

Optimal Flight Path of Flying Fish

Abstract The flight path of flying fish is analyzed by two methods, a simple analytical method and a numerical method based on optimal control theory. It has been observed that flying fish fly over

Allometric constraints on stability and maximum size in flying fishes: implications for their evolution

The accepted model of evolution of flight in flying fishes (by extension of ballistic leaps) is flawed and it is proposed that evolution of lift-supported surface taxiing in half-beaks with enlarged pectoral fins (enhanced by ground effect) was an essential preliminary.

Evidence is presented to show that hypertrophied pelvic fins in four-wingers are required to solve problems of stability in pitch, rather than to decrease wing-loading.

Evidence is presented to show that it is unlikely that flying fish are capable of flight at temperatures below 20 °C because of fundamental limitations of muscle function, and to indicate that smaller flying fish gain positive benefits to their swimming performance from possession of expanded lateral fins.

Using the pitching moment equations for gliding animals and by discussing potential sources of roll and yaw stability, it is found that flying animals possess a far higher degree of inherent stability than has generally been recognized.

The pattern of air flow over bird wings, as indicated by pressure-distribution data, is consistent with aerodynamic theory for aeroplane wings at low Reynolds numbers, and with the observed lift and drag coefficients.
