Aerodynamic of Flying Fish

Aerodynamic of Flying Fish
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 fish to aerial locomotion have attracted great interest

USS Flying Fish (SSN-673), a Sturgeon-class attack submarine, was the third ship of the United States Navy to be named for the flying fish, any of number of fishes of tropic and warm temperate seas whose long winglike fins make it possible for them to move some distance through the air.

USS Flying Fish (1838), a schooner, was formerly the New York City pilot boat Independence. Purchased by the United States Navy at New York City on 3 August 1838 and upon joining her squadron in Hampton Roads 12 August 1838 was placed under command of Passed Midshipman S. R. Knox.

Flying Fish Distribution and Description

Flying fish live in all of the oceans, particularly in tropical and warm subtropical waters. Their most striking feature is their pectoral fins, which are unusually large, and enable the fish to hide and escape from predators by leaping out of the water, taking short gliding flights through air just above the water's surface. Their glides are typically around 50 metres (160 ft).Flying fish taking off

To glide upward out of the water, a flying fish moves its tail up to 70 times per second. It then spreads its pectoral fins and tilts them slightly upward to provide lift. At the end of a glide, it folds its pectoral fins to
