- The flight capabilities of flexible-winged insects are the subject of Professor Haibo Dong's research in the Flow Simulation Research Group at the University of Virginia. His team uses high speed video cameras and advanced computational systems to build 3-dimensional models of flying insects and the vortex structure of airflows created by their flight. The project's goal is to improve the design of small flying robots.
Their wings are covered with small spikes that are probably vortex generators, used on certain airplane wings to improve laminar flow and delay separation.
Akin to the tubercles found in certain aquatic animals. Interesting. Thank you. Also of note is that one half of its bilateral symmetry can be likened to a two-masted Schooner, perhaps taking advantage of Slot Effect. Good luck and thank you.
Very nice. I like the sound of that!!! Maybe... let me think about this ...
Ooooo.oooooooooo
Do you analyze the hollow bone structure and the cone shapes under the wings as a system of levitation for dragonfly flight? It seems that their wing movement is performing a control system for their flight rather than the actual flight/lift mechanism.
This is really helpful thanks to TH-cam. Been stressing about how to crest a dragon fly, for my daughters project. This makes it so easy and simple
what do you mean by cresting a dragonfly? Are you making a toy robot for your daughter? Thats so cool
That is just TOO cool. Awesome video! Love the slow motion part.
the sound thAT IS SO highly pleasing. love those good vibrations dragonflys bring with em Just amazing~ Totally Tubular and Excellent . Rock on !!!!
PHENOMENAL. Mother Nature is truly incredible, and so is evolution
This is really cool!
you are amazing,I cant' wait to see this tech used in future consumer based flying vehicles/spaceships 💪🖖
Нет ничего, чего бы не смог создать или повторить человек. Респект вам!
Thanks for sharing this amazing video!
Very interesting, great topic to discuss
So cool!
Nice vedio 👍joined stay connected
I'm no expert, but it seems more of treading air (opposed to treading water etc..) than aerodynamic lift.... Cool!!
(Note: I will watch the video again later, can't hear it now because of location.)
Is there an advantage of 4 wings ?
Redundancy, not sure beyond that
Good question. 👍
The use 22 percent less energy to fly when the beat their wings out of phase
Like he says maneuverability. But we don't generate maneuvers by moving the entire wing
The 4 wings work together to create swirling vortices of air under the wings which enable them to hover by barely beating the wings on top of the very vortices that those 4 wings create, like tapping on firm columns of air. This enables the hovering, acrobatics, reverse flying, and high flying speeds of these masters of the air. Just enter "dragonfly flight vortices" in your search and you'll find plenty of good material and illustrations.
God is great! Wow how wonderful
