Dune ornithopters flap their blades in the wrong plane for vertical takeoff

- darkest_ruby 3y agoAs if this was the only problem with them, such machines are incapable of flight in general.
- vkou 3y agoNeither can bumblebees, and yet...
- jojobas 3y agoThey can fly if they flap their wings in appropriate directions. https://www.youtube.com/watch?v=4C9LTZCmb8Q https://www.youtube.com/watch?v=4C9LTZCmb8Q
- relaxing 3y agoI looked for more videos of this and they seem to only show it in slo-mo or for 1-2 seconds at a time. Why no videos of sustained flight?
- hkwerf 3y agoStarting flapping in that orientation may give very good control over forward/backward forces until you're ready to lift off. Once they lift off, the blades are too fast to observe, so they may well apply an additional rotation. Mechanically, they're clearly capable of such movement.
- SiempreViernes 3y agoYeah, I think this is most sensible take.
- almostnormal 3y agoThe forward wings produce forward-high to rear-low airflow, while the rear wing produces a rear-high to forward-low flow. Those join in the middle to a top-down flow.
- Lanrei 3y agoAssuming that they're capable of changing the wing angle of attack, they seem to be doing the same motions that dragonfly wings make during flight, including take-off. Here is a slow motion video of one taking off (note the vertical motion of the wings): https://www.youtube.com/watch?v=KOc8WTzMljw https://www.youtube.com/watch?v=KOc8WTzMljw
- andrewstuart 3y agoI’m pretty sure Dune is fiction. BBC has plenty of documentaries if fiction upsets you. Pedants angsting over the reality of fiction does spoil the fiction so best to ignore such peoples laments about how things are unrealistic.
- RedShift1 3y agoDune is not fiction, I saw the video footage myself.
- andrewstuart 3y agoWell if it’s a documentary then how the wings flap is important, and not spoiling the fun with pedantry.
- drivingmenuts 3y agoA friend of a friend who is an ornithopter mechanic says it has something to do with unobtanium. TBH, I thought it was boring, so I quit listening, and this spicy bird was telling us about her desert religion thing. I was a bit drunk on spiced rum.

- mattnewton 3y agoJust wave your hands and say “Holtzman” effect, to get back to the story. This bothers you but the shields don’t?
- vertis 3y agoI suspect if this bothers them many things bother them about the science in these movies.
- sirobg 3y agoI got curious when I read this comment https://twitter.com/BrunoPresents/status/1779373530951360622 https://twitter.com/BrunoPresents/status/1779373530951360622 and did some research. I found a Nature article: https://www.nature.com/articles/521S64a https://www.nature.com/articles/521S64a Their flight mechanism is amazingly sophisticated (and efficient, cf the experiment showing that bees can fly at height above Mount Everest and below sea level, which is nuts) but it seems it has nothing to do with some "vibrational field". If someone here knows more about this, definitely share!
- schrectacular 3y agoDoes the universe have surface tension? Oooohhhhmmmmmm.
- cykros 3y agoArguing with the physics of Dune is like taking issue with the way time travel works in Back to the Future. Still suits honestly have the more glaring issue, and that's one that's apparent not just on film, but in the original text as well. Anyway, it's not science fiction; it's space fantasy. Let it be.
- Retric 3y agoIt’s IMO more interesting to look for reasons that something could be consistent than try and point out issues like this. Still suits could have some ‘sci-fi’ scale thermal battery assuming Arrakis gets cold at night. You could get warm enough during exercise the body starts to sweat while the suit generally feels cool in the sun and sufficently warm at night.

- SiempreViernes 3y agoThe sequence shown is clearly intended precisely to highlight the reality of the ornithopters, being a variant of those sequences in war movies that just show cool shots of real things being prepared for a mission. Since the movie chooses to depict these sci-fi elements with that type of images of, I think it is fair to scrutiny them for realism.

- episteme 3y agoI suspend my disbelief by thinking that it's quite possible they made different scientific discoveries than we did. Either different order of discovery, different constraints or things we still haven't figured out. That allows for engineering that looks different to what we are used to but if we knew every detail of how they worked it would make sense.
- throw0101c 3y agoThe scene in the movie where they're first shown: * https://www.youtube.com/watch?v=yT4nVWs7434 https://www.youtube.com/watch?v=yT4nVWs7434 Somewhat related, the sound design team (who won an Oscar for their work) used cats purring, beetles fluttering, and the canvas strap of a tent in a 100mph wind for the sound of the ornithopters (at 2m40s) * https://www.youtube.com/watch?v=-v2pbKWIV_g https://www.youtube.com/watch?v=-v2pbKWIV_g Also, for the desert mouse (muad'dib) they used a Swedish baby red squirrel (named Baby Pear); interview with the person who originally recorded the squirrel (Dani Connor): * https://www.youtube.com/watch?v=YtfzjehDg74 https://www.youtube.com/watch?v=YtfzjehDg74
