00:00Dragonflies are one of nature's most powerful and agile flyers, hitting straight line speeds of almost 40 miles per hour.
00:10They can dart in any direction and accelerate at 4G, and a jaw-dropping 9G when making sharp turns in pursuit of prey.
00:20Equivalent to the maximum force a fighter pilot can withstand before passing out.
00:26This incredible manoeuvrability comes courtesy of their two sets of wings.
00:33While the wings of most other insects are operated by muscles connected to their upper body,
00:40the dragonfly boasts four separate flight muscles attached directly to the base of each wing.
00:47Each muscle operates independently, enabling four distinct flight modes.
00:54Counter-stroking, where the four wings beat 180 degrees out of phase with the rear, generates a large amount of lift, perfect for hovering or slow flight.
01:08During phase-stroking, the hind wings beat 90 degrees ahead of the front, which creates more thrust and less lift.
01:17This is where the dragonfly gets its straight line speed.
01:21Synchronized stroking, where all four wings beat together, gives maximum thrust and allows rapid changes in direction.
01:31And finally, gliding. The wings are locked out straight, a technique also used within all other flight modes.
01:40Combined, these flight modes make the dragonfly one of nature's ultimate fliers.
01:52янty birds have engagement underneath the axis in the center of phase with the wind Dogontinite.
