Winglets also increase the effective aspect ratio of a wing without greatly increasing the wingspan. Extending the span would lower lift-induced drag, but would increase the parasitic drag and would require boosting the strength and weight of the wing. How do winglets work? Winglets dispense the ...

The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as str...

euryale, probably due to letter differences in wing morphology. Conclusions Coexistence between sympatric sibling horseshoe bats is likely allowed by a displacement in spatial niche dimension, presumably due to the wing morphology of each species, and shifts the niche domains that minimise competition. ...

A Discus Launch Glider (DLG) is a type of radio-controlled glider specifically designed for hand launching. Unlike traditional gliders, which rely on being launched from a slope or with a towline, DLG gliders are launched by hand, similar to how one woul
