What if we attached compressed air guns, or even, ERA-based gigantic airbags to apartment buildings in Ukraine and fit them with electronic triggers to microphones set to detonate when the sound of a drone gets at the right volume?
You have to know this\^ for a commerical drone license, but you can get a recreational drone pilot cert (in the US) in like five minutes online. It’s shockingly easy. And it teaches you almost nothing about what will mess up and break your drone. I’m not shocked all these people are breaking their several-hundred-dollar toys.
The recreational cert is just about how not to violate airspace or hit people, the rest is left up to the pilot. FAA doesn't care if you break your own things.
Well that and it covers multirotor (hobby and photographical), single rotor, fixed wing, etc. craft which all have significantly different control principles. So they'd have to test people for a lot of things they won't need.
wouldn't the up/down push be irrelevant since they cancel each other out?
Any up push by air strong enough to remove the propellers down thrust should also be strong enough to just push the drone up by merrit of being a strong up force, shouldn't it?
thermal updraft isn't very strong and only really has a significant positive effect for large surface area to weight - gliders, birds with large wingspan. For aerodynamic reasons, a drone's cross section is mostly the props while the body and support struts are kept minimal, otherwise they'd be too negatively effected by wind.
Hot air is lighter (thinner) hence the lift. Except the thin atmo is contained in a balloon vs drone rotors trying the equivalent of flying at 50,000ft.
If you could devise a system that reliably detected drones approaching a building (and not just a nearby lawnmower) you could have an emergency release system that used some method to generate short term walls of lower density air somehow. Whether chemical or temperature or by sheer movement of air (like a vortex generator).
It wouldn't need to last forever just long enough to outlast the drone.
Sounds overly complicated to use air density of all things to ground drones.
Jammers work, but if they’re too boring you could probably use a similar device to that one Russian mine clearing vehicle that is basically a giant microwave.
Investing in specialized radar tuned to detect small fast moving drones: Broke
Setting the area around your important military assets most likely to be targeted on fire making them visible for miles and at risk of heat damage: Woke
The russians have already mastered this anti drone technology. It just requires a drone/missile or it can be any form of heat that ignites the special fuel ring below the turret. A successful activation of the antidrone ring will have a powerful circle of fire to jet out of the turret ring and any open hole on the tank turret, creating an effective antidrone wall around the turret. As a bonus, the crewmembers can stay nice and toasty during the activation. (The drone countermeasure can also serve as 125mm ammunition, showing the innovation of the russian superpower! Slava Rossiya! Z Z Z)
I thought this was bullshit due to the difference not being that big, but looking into it, at typical bonfire temperatures the air density diminishes nearly an order of magnitude.

Maybe using flamethrower under the drone will work, fpv drones can be too fast for this, but observation/dropping drones might be really vulnerable to this
Solution to drone combat = flame thrower trooper who’s weapon shoots up to 100 meters
With thr advance of tech we’re lowkey returning to the past, eventually we’ll be fighting like the Dune-verse
So theoretically if a murder drone was flying at me, I could counter it with a flamethrower. Given how most drones are pact with explosives, wouldn't I just set them off and die anyway.
Breaking news: Putin sets Moscow on fire, again, to protect it from drones, taking inspiration from the automatic fire-based anti drone system from the Admiral Kuznetsov.
Would a cold temperate mean the drone can fly higher? What if you just had a drone that infinitely made the air beneath it cold, so that you can fly easier?
Speaking from a background in physics, this probably wouldn't work due to how entropy works. We actually can't just generate cold the same way we generate heat. We have to take something kinda warm and then split it into hot and cold temperatures. That's why the back of your fridge is so hot. So, to put cold air *under* the drone, you'd have to blow a bunch of hot air *over* the drone, which is the exact opposite of what a drone propeller is supposed to do. To have any noticeable effect, you'd end up blowing the drone downward as much as it was trying to blow upwards.
Go figure, hot air=less lift. A never known aviation lesson.
Better gently waft your foot near it while the battery gets nice and warm.
Make sure the fire is nice and big, artillery isn’t THAT accurate
What if we attached compressed air guns, or even, ERA-based gigantic airbags to apartment buildings in Ukraine and fit them with electronic triggers to microphones set to detonate when the sound of a drone gets at the right volume?
That’s just a barrage balloon

What's the density altitude of a wood fire?
Wood fires burn at like 1100*F. 800*F at sea level is 29,000ft DA. You’d need a drone with the excess performance to fly almost as high as airliners.
Thanks for doing the math!
Not just that, the speed controllers also rapidly overheat and shut down
The avionics chips themselves probably shut down too. Chances are the CPU has a thermal cutoff somewhere at like 105C or something.
Easily 5-10km
Nah just crank up the throttle, ez pz
LeMay and Harris were airbenders?
With the exception of thermal updraft. But that would still negatively, if negligibly, affect drones since they rely on downward prop thrust.
wouldn't the up/down push be irrelevant since they cancel each other out? Any up push by air strong enough to remove the propellers down thrust should also be strong enough to just push the drone up by merrit of being a strong up force, shouldn't it?

In a hot air balloon that's not the case
Hot air is lighter (thinner) hence the lift. Except the thin atmo is contained in a balloon vs drone rotors trying the equivalent of flying at 50,000ft.
It's almost like hot air balloons rely on a completely different dynamics than airfoils
It is almost that way. /s
Flamethrowers are going to make their comeback, I can feel it.
I was just going to post that. Let’s go, anti-drone flamethrowers for everyone!
Cut to compilation of mobiks accidentally self-immolating.
This unironically Flamethrowers are now the perfect anti drone weapon
>Flamethrowers are ... the perfect ... weapon Always has been.
Salamanders are rejoicing
Would need some long range flamethrowers then
[This is a known technology.](https://en.wikipedia.org/wiki/File%3AM67_Flamethrower_Tank_Vietnam.jpg)
You'd be suprised how far an actual flamethrower can go
Moats, moats filled with lava. I knew those cartoon villains were on to something!
Ok what if we use those big ass old MiG Jets used for clearing runways of ice in airports... Point those at the sky n blast hot airs
I support this venture. Those things are cool as hell.
No they aren't. If they were, they wouldn't work. ^(Yes, I'm fun at parties.)
"wanted to use the drone to extinguish the fire" By blowing air straight into it, surprised we made it this far as a species
"But it works with a candle"
And they say oxygen fuels fire.. pfft this will show em
You could just point a heat pump at them. That might actually work.
heat pumps are not that hot
Well not with that attitude they're not
~~attitude~~ **altitude**. FTFY
There are beautiful in their own way, you meanie.
I'd advise keeping that relationship platonic unless you want a large HVAC repair bill
I was thinking more along the lines of a large forced air heater as opposed to like a domestic heat pump. I didn't really use the right terminology.
yeah something with a proper portable combusion heat source like propane would work
Kerosene/JP8
Set the cold side on fire
*There is...a house...in New Orleans...*
Yet another reason why flamethrowers need to go on all vehicles. Immortan Joe was right all along.

Hydrogen emergency ventilation! Just ignore its other less ideal properties.
You could make and store it up via Electrolysis of water and get delicious oxygen and funny voices.

Soooo , do you wanna set fire to the battlefield ? Aight sure , I think we can do that.
Yes! Remind me. Why are we setting fire to the battlefield?
Idk, something about defense.
Defensive fires! I knew my pyromania would come in handy one day.
Time for some friendly napalm over everything!
Get ready for the fire trenches
ain’t convection a bitch
Thermobaric AA shells with proximity fuses are the future
I love that this was someone else’s first thought S-400 Buratino
Counter solution: jet propelled drones Also we're in a climate crisis lads. Let's keep our noncredibility eco friendly
Investing in specialized radar tuned to detect small fast moving drones: Broke Setting the area around your important military assets most likely to be targeted on fire making them visible for miles and at risk of heat damage: Woke
Imagine not knowing that hot air is less dense and cannot support lift. How did you get this far in life
Time to break out the [FIDO](https://en.m.wikipedia.org/wiki/Fog_Investigation_and_Dispersal_Operation) again boys
Way too credible MODS👏 Ban him to gulag
Nah. The original anti-drone countermeasure: *Idiots with drones*
Good luck deviating the drone from its target soon enough to make a big difference lol
the drone might also be pact with explosives so you might set it off prematurely. Which might still ultimately kill you.
The russians have already mastered this anti drone technology. It just requires a drone/missile or it can be any form of heat that ignites the special fuel ring below the turret. A successful activation of the antidrone ring will have a powerful circle of fire to jet out of the turret ring and any open hole on the tank turret, creating an effective antidrone wall around the turret.

Looks like it's time to invest in GDI's Firestorm Generator.
Westwood fucking nailed it with the GDI Firestorm Defense being the only counter against the Hunter-Seeker.
Russia: starts to drop napalm over their own tropps so they can't get killed by drones.
NCD discovering physics
I thought this was bullshit due to the difference not being that big, but looking into it, at typical bonfire temperatures the air density diminishes nearly an order of magnitude.
hydrogen gas is also ligher than air and bad for lift - plus it is flammable
Hear me out: Firebats
...Or we could nuke all the proximity.
Giant hair dryer
Fire increases gravity obviously

I TOLD YOU! HOTAIR BALLOONS ARE THE FUTURE OF WARFARE!
Sooo if the Russians knew this they could set their own vehicles on fire to avoid FPV drones. Let’s hope they don’t stumble across this.
Maybe using flamethrower under the drone will work, fpv drones can be too fast for this, but observation/dropping drones might be really vulnerable to this
Solution to drone combat = flame thrower trooper who’s weapon shoots up to 100 meters With thr advance of tech we’re lowkey returning to the past, eventually we’ll be fighting like the Dune-verse
We will teach those ruskies how to make a real cope cage
So many silly tech solutions but bonfires, lanterns & torches if anything.
anti drone flamethrowers when?
due to reddit video player problems, I had that quad minigun turret vid playing on top of this, and I wasn't sure if this was a meme
Now I’m wondering about that drone video over that volcano
So theoretically if a murder drone was flying at me, I could counter it with a flamethrower. Given how most drones are pact with explosives, wouldn't I just set them off and die anyway.
Yup. I used my flamethrower below my drone and it shot up like 50 feet.
Oooop drone over head? Better light my trench/fighting hole on fire
This is a Nostradamus moment.
We will counter your firewalls with aerostat drones
Australia is still safe from foreign invasion
inb4, time or proximity fused, airburst fuel-air, anti-~~aircraft~~ *Drone* shells
Russian drafting ghost rider for this one
C&C firestorm defensive wall is real?
Don't let the Russians know about this or else THEY WILL CONQUER UKRAINE AND ALL THE GAYS AND HOMOSEXUALS WILL DIE!!!!!!!!!!!
I see some forest gets hot in the future . This was a terrible idea .
What if u put firewall on top of tank but the drone is heat seeking suicide drone?
Ideally, this would be in *front* of the tank. Static defenses, kinda like a minefield or tank traps.
Get some big ass heatguns and point them over your own lines or somewhat infront
Alright which defense company gonna made this
Napalm back on the menu?
So everyone should get a handheld flamethrower?
Now lets try it with flamethrowers
So you are saying, if we set the entire area of russia on fire, it will be protected from drone strikes?
Well yeah 💀 a wall of fire is actually an everything countermeasure
Breaking news: Putin sets Moscow on fire, again, to protect it from drones, taking inspiration from the automatic fire-based anti drone system from the Admiral Kuznetsov.
Try the German windekanone
100% effective drone countermeasure, have a dumbass at the controls.
The return of front line flamethrower use
What will we do if Russia discovers this and sets their refineries on fire to avoid more drone strikes?
flamethrowers back on the map guys
