- jcims 5y agoI wonder what it would sound like if they went to a higher blood count on the props. For some reason they don’t seem to have garnered much attention yet, but eight blade props are extremely quiet relative to the smaller prop counts. Here’s example comparing a typical 2 (or 3) blade 5” prop to an 8 blade on a drone. The 8 blade is smaller, 3” i believe, with similar performance but a major difference in sound. https://youtu.be/1nk74KEIc2c?t=136 https://youtu.be/1nk74KEIc2c?t=136 Here’s another one with two 8’s stacked on each motor. https://youtu.be/i58cC2hntqQ https://youtu.be/i58cC2hntqQ Also for all the time spent developing the aircraft and the importance that perception plays in selling it you would think they might have put a little more effort in figuring out how to efficiently load it. That was torture watching haha. (wtf Apple, the ’haha’ in my last sentence autocorrected to ‘gays’?!? I wonder what i haven’t caught)
- DaveExeter 5y agoPropeller efficiency drops off with increasing blade count.
- Saris 5y agoI think from my limited knowledge of propellers that more blades is less efficient, so it would lower flight time.
- all2 5y ago> higher blood count Made me chuckle :)
- jcims 5y agolol I’m leaving it
- NickNameNick 5y agoA lot of the drag on a prop comes from the tip of the blade. More blades means more drag.
- LargoLasskhyfv 5y agoWatching this, several observations: Why does it have to be in a cabin, even lifted up into it, while most pallets/boxes are shrink-wrapped already? If avoiding shrink wrapping because plastics, use standardized hoods with deposit, if you have to. Works for pallets/boxes already. They could do with the net, like shown there anyways. Also some lighter mechanism which goes into the pallet/box from below, since they are standardized. Or good old rope/chains/somesuch. Lastly, why the EFFING EFF is he wearing a helmet while riding a Cargo-TRI-Cycle, which won't go above 25kph ever? Also: Can I have one with joystick to sit in? *g*
- p_l 5y agoCabin also reduces drag, even if it might seem low. Combined with weatherproofing and general enhancement to protection in case anything comes loose, it simply makes sense to me.
- LargoLasskhyfv 5y agoCould be. But I've been under the impression they don't move that fast. Cabin or not. Perceived benefit seems to be more direct line of flight, if allowed at all.
- AHASIC 5y agoI think the netting/chaining of cargo won't work as the winds here in Germany can get quite strong, making the cargo's weight less balanced and messing up the drone's stability.
- LargoLasskhyfv 5y agoThen use two L-shaped bars in between the landing skids, fixed to the top structure and/or landing skids. Have two other bars swing down from the top on the other side of the pallet/box, have them lock in. Should be still lighter. Also I know about the winds because I live in HH and bicycle there all the time ;) Shouldn't really matter when you think about what even things like Ardupilot or similar firmware for drones can do to stabilize flight in all sorts of situations. It's just a matter of scale. And that thing has way more propellers to dynamically counteract any imbalances than the small hobbyist things. I don't know. It looks overdesigned to me. Form should follow function. In vague comparison this looks like the first railroad wagons for passengers still somehow looking like horse-drawn chariots. Makes no sense to me.
