--- Quote from: mikeselectricstuff on December 21, 2018, 11:51:22 pm ---OK so how much damage could a drone actually do - maybe take out one engine at best.
Aren't planes designed to be safe if an engine fails, as an engine failure could happen at any time...?

--- End quote ---

yeh, afaiu losing an engine on takeoff is worst case and still once past the point where the takeoff can be aborted the plane must able to take off on one engine

Please stop suggesting birds too. Falcons weigh less than all but the small end of Drones the blades of which even these will damage if not kill it - dumb idea!

Assume a current medium drone of 2kg mainly plastic or carbon with a few lumps of 30mm diameter motor for metal. and a plastic bag full of lithium and paper. No more risk I suspect than a bird strike allowed for by testing Pelicans and some other waders are 5kg.

Largish Drone 5kg speeds approaching 100km/hr is some cases. Assuming and this is a big ask the drone hits an engine or cockpit window dead on it is then lumps of metal weighing about 4-500g 50mm across. Chances are there will be damage if not loss of one engine, windows most likely will deflect it.

Large Drone 10-20kg hits an engine BOOM and likely would damage a wing, fuselage or even take out a cockpit window.

Image below is 15kg of off the shelf commercial Non Geofenced Drone 107km/hr top speed and with a double load of batteries instead of the camera 30 minute flight time. About 1.5m across Here Falcon here come get dissected by me.



All of this assumes the intent is to cause harm instead of just being a PITA for reasons....

If you want to take out a plane you don't use a drone you take your 50 cal Rifle and scope  and throw high speed precision lead at it. Or a Bomb or ....
Bud:
The larger and heavier a dron the less maneuverable it is. And what is the point of putting a second battery instead of the camera if that reduces maneuverability even more. Without a good guidance system the operator will just be taking chances of hitting the target even a large target. And you need to Deliver that monster to the area first. Speed has little value if maneuverability is shit.
beanflying:
Because the camera shown above is NOT used to fly it with. One of intended uses of that drone is high grade aerial photography or video or whatever payload you like.

The little blob on top of these is the flight camera, no geo fencing and way over 100km/hr.

That 500m max range claim I read in the news is ridiculous. First of all you can use cellular network to control it from any place in the world (with video feedback). Or simply use long range low speed transfer like LoRa. Secondly it can be autonomous.
