Jan 22, 2015 · Flies can hover, move vertically, and even fly backwards, tantalizing you with your inability to catch the little buggers. Most flies flap their wings over 200Hz, or 200 cycles per second. A tiny ...

An Anthomyiidae species showing characteristic dipteran features: large eyes, small antennae, sucking mouthparts, single pair of flying wings, hindwings reduced to clublike halteres. Flies are insects of the order Diptera, the name being derived from the Greek δι- di- "two", and πτερόν pteron "wing". Insects of this order use only a ...
An insect's ability to fly is perhaps one of the greatest feats of evolution. Michael Dickinson looks at how a common housefly takes flight with such delicat...

Without spalt, the flies survive, but are flightless. The flight muscles no longer react to tension and thus behave like normal leg muscles. On the flip side, the scientists succeeded in creating flight muscle-like muscles in the fly’s legs simply by inserting spalt. These results could be medically important, says Schnorrer.

Okay, so the wings are the key to making something fly—but how do they work? Most airplane wings have a curved upper surface and a flatter lower surface, making across-sectional shape called an airfoil(or aerofoil, if you're British): Photo: An airfoil wing typically has a curved upper surface and a flat lower surface. This isthe wing on NASA's sol...
If you've ever stood near a helicopter, you'll know exactly how it stays in the sky: it creates a huge "downwash" (downward moving draft) of air that balances its weight. Helicopter rotors are very similar to airplane airfoils, but spin around in a circle instead of moving forward in a straight line, like the ones on a plane. Even so, airplanes cre...
Generally, the air flowing over the top and bottom of a wing follows the curve of the wing surfaces very closely—just as you might follow it if you were tracing its outline with a pen. But as the angle of attack increases, the smooth airflow behind the wing starts to break down and become more turbulent and that reduces the lift. At a certain angle...
Now a plane doesn't throw air down behind it in a completely clean way. (You could imagine, for example, someone pushing a big crate of air out of the back door of a military transporter so it falls straight down. But it doesn't work quite like that!) Each wing actually sends air down by making a spinning vortex(a kind of mini tornado) immediately ...
TEDxCaltech. • January 2013. Read transcript. An insect's ability to fly is one of the greatest feats of evolution. Michael Dickinson looks at how a fruit fly takes flight with such delicate wings, thanks to a clever flapping motion and flight muscles that are both powerful and nimble. But the secret ingredient: the incredible fly brain.

Video tape of these models showed that the wing can form a large vortex at its leading edge. This vortex augments the forces generated by the insect and provides enough lift to keep the insect in flight. By changing the angle of attack of the wing, the fly can change the size of the leading edge vortex and how much lift is produced.
