ALTURA DRONE - STORM FLIGHT - 5.12.2013 from Aerialtronics on Vimeo.
Pretty impressive flight by Aerialtronics Altura multirotor in some heavy winds. Intuitively, the design does not look optimised for flying in heavy wind, as its frontal area looks rather large.
Comments
I do apologize Oliver, I didn't expect you to see my comment from your world record high horse!
Just to be clear, the comment wasn't for you, it was for people with a sense of humor.
(And generally to support what I think is impressive flight controller performance, and balls from the pilot and support crew)
@ leronardthall:
Speaking of knots, I beg your pardon but your comment regarding meters/second being "recognized worldwide" is absolutely incorrect in regard to aviation, which after all is what we're (mostly) doing here. With the exception of some former Soviet block countries the aviation world flies in knots and feet, and expresses wind speed in knots as well. The closest thing to "meters per second" is feet per second, which is used only for vertical motion (where it is also useful for multirotors).
There are a number of reasons for this, not the least of which is that many metric units, regardless of how easily they can be manipulated, are of awkward size for many of day-to-day applications. They are often too fine (the gram and the millimeter) or too coarse (the kilo, the meter). The absolute values of non-metric units tend to be directly scaled to human activity, while the base metric units are abstractions which may or may not fit a particular activity very well. But that's off topic here. Meanwhile, though, I suggest that we here stay as much as possible within internationally recognized aviation nomenclature practices.
@Robert, I have every confidence that my hotrodded Hex would handle that breeze with no problems at all IF I first stripped a bunch of weight off and reset some pids from "greyhound bus" mode to "Focus ST." But since I, like F.F., already hold numerous world records, I don't feel much need to go to all that trouble. I do have some nice video of a TRex 450 being flown manually in 40+ knots... wheeeee!
wow! 56mph. That is pretty good. You Poo Pooers I bet haven't tried to stand in a 50+mph wind. That is the stuff where you stand at 45 degrees to the ground waiving your hands in the air and not falling over. That is stiff. Uh, I don't weigh 300....
Oliver, 56mph is indeed pretty dang high winds. Try it for yourself and post the video.
@leonard. They are not using arducopter. Their kit is quite impressive (and expensive) they had an altura frame with full HD live video link with them when I talked to them at OHM2013. There they told me that they used their own designed.
I had a look at the website and this may not be using Arducopter. In that case, Hats off!
I am glad people are catching on how loiter or gps hold should be tested and demonstrated, high swerling and/or gusting winds.
Nice Video!!
It is nice to see loiter being tested in the way it was designed to be tested :) (I assume this is Arducopter)
As for the wind speed, 25 m/s is both impressive for loiter and, and in units recognised world wide (unlike mph). The 3dr Quad will do 17m/s at maximum speed, 54 kph, 33.5 mph for those living in the dark ages :). So I would say that most quads around wouldn't be able to do this.
For those that haven't discovered an online unit converter. 25m/s is, in order of usefulness, 90 km/h, 48.5 knots, 0.0734 mach, 8.33910238e-8 speed of light, 55.9 mph.
And Robert, yes your flight was in higher winds, in a messed up toilet bowl. However, you didn't do the basic calibrations for Loiter and you kept getting scared and flicking back to stabilise. :) This bloke is demonstrating confidence and trust in his loiter.
Now for those of you that don't have a smile on your face reading this. I AM JOKING AROUND. Ok, humor may not be my strongest suit but you have to forgive a bloke for trying!
Just under 5 rods/second
How fast in rods?
