Description
Drones are only useful when they’re in the air. And thanks to the limited charges provided by batteries, drones spend a lot of time not flying. Electric drones are often limited to just 20 minutes of air time before they have to land and get new batteries, or wait for the old batteries to charge. With hydrogen fuel cells, This drone could spend up to two hours hanging in the sky, be refueled almost instantly after landing, and then take another 120 minutes in the air.
There are 4 independent hydrogen cannisters socketed in the body with easy acces, no need special ability to replace them for full ones so Drone is operation-ready in few second again. In the case below there is sensor system integrates daylight HDTV camera, image-intensified HDTV camera, laser illuminator and laser distance measure system. The full-motion video from each of the imaging sensors can be viewed as separate video streams or fused. System is designed to work autonomously to cover large landscape in area. Drone is designed to provide control and overview from above. It can be also used as part of traffic control system in big cities or it can make detailed 3D maps in unexplored areas.

i see here a well-executed 3d model representing a fairly standard, be it angular, drone with a few structural design issues.
first the good, the presentation, nicely done, nothing else to say about it, nice blueprint images and details hot to go with them.
the colors and details, again, nicely done, nothing too fancy or complicated making it look like the real deal.
then there is the bad part....
these mostly design choices related and not the 3d execution, the first big no-no i see are the propeller supports, placing these outwards on the outside of the bumper ring adds unnecessary stress to the bumpers, and placing them on the bumpers adds to the length of the propeller support as these are quite thin, adding wobble and instability to the whole design, and for a surveillance drone this is unwanted... hence you see most similar drones with supports coming from the center which is inherently more stable.
the second thing i noticed is that there are 4 canisters... why? design wise it makes more sense to design a cap-shaped cannister you place on top and in the center of the design. or a toroid ring canister that goes around the center raised part.
besides decreased part total count, less possible leaking connection points and improved refueling speed, this also adds stability, for center mass will be more central. that and the risk of unevenly draining or even losing 1 of the 4 canisters as is might also add to instability.
the stereo vision camera looks great, might make for a good VR experience when the lenses are placed far enough apart. whatever else you can do with them also sounds nice, but that is text fluff e.deviantart.net/emoticons/let… " width="15" height="15" alt="
what i miss however are landing struts to protect it.... you really don't want to land on the camera itself, not only is landing on a single point unstable.... it also might damage the camera beyond repair.
that and you have a point to grab the drone from midair if you don't want to land it... grabbing the camera is usually also not a great idea (damages servos and such).
a good design choice IMHO is the dual rotor setup that increases stability and lessens centrifugal rotation at the cost of a few more parts.
all in all, it feels a bit incomplete design wise, but that what is there is made a proper.

Hi I wrote you reaction time ago but it has been lost somehow. in short terms I agreed on most ofobjections it was quick job. not compicated and I had to make compromize. only one point. landing is done on that box and all device inside are protected so it should be problem to land on it. regards.

if the camera box and servos are strong enough, sure why not.

I see that the hydrogen powered drone concept has been very much improved with your work!

I really like this drone Peter. A very well thought out concept although I feel perhaps a bit more refinement of the Image system might be warranted. For a system meant to be the purpose of the drone it seems a bit underwhelming.

tnx you mate. could be. Honestly it is not finished. I did quick render as I did model time ago and since that it was unfinished. Therefore I dod only 1 render as well.

Very cool, mate!
I have a base idea for a sci-fi weapon. Would you consider doing it in some form?

hi mate. Sorry but can not take any oter job these days....

It's more like a "suggestion" anyway, to be honest.

Can this drone be "weaponised" by installing a command to remotely overheat the hydrogen cannisters?

probably yea mate

Love it...and full of cameras! now here's a challenge for you... make the remote control

looks kind of awesome. though i would have like to have had something to show the size of this drone

yea those from these days are quite small.

yea i mean hell we have some drones cdn.trendhunterstatic.com/thum…

This looks great, dude. Only qualm is that I see no landing gear. I would hate to damage the expensive sensors on landing.

tnx you there are skies at the bottom of case but it is not visible from this angle very well.

Nice concept! Based on it, you can make a real model.

That is really nice. Interesting concept with the energy source. It makes it more effective.
But to have great processing power such as you say then how far can the HDTV cameras recognize photos and video before it is unfocused?
👍: 0 ⏩: 1
hi. tnx you. it is not my original idea. There are some prototypes of drones working on this principle in real world. When I discovered them on internet I decided to make oy own concept. And about that processing power. You can imagine how much we can hide behing Advance sensor system. mainly when we dont have to make it workable it in real world.

That would be amazing. But very costly in the end to do.
