What would happen if a multirotor were sucked into the engine of a passenger aircraft?

About the only thing that would happen is there would be some noise and a destroyed multirotor. At least until you got up to a certain size and more solid material one. (JMO)
 
Hi guys it will destroy the jet engine even a small bird will, as it will damage the turbine blades and if one is out of balance , the engine at 161000 rpm it will shatter in side

That video confirms that birds are not a big problem with jet engines, although when you start talking about big birds like geese I am sure it then can cause some damage. I am sure they would be more of a problem for prop planes.
General Electric CJ-610 (Learjet) is single spool -
100% RPM is 16,500 RPM
The larger the diameter, the lower the RPM. The smaller the diameter, the higher the RPM.
For instance, the JT8D turbofan engine has twin rotors, N1 and N2.
The N1, which includes the fan, low pressure compressor, and the low pressure turbine has a maximum RPM of about 8,000. The N2, which includes the high pressure compressor and the high pressure turbine has a maximum RPM of about 12,000.
 
Hi Guys dont forget multirotor have very hard parts like Motors, and one of these hitting the turbine blades will snap or bend them, this will put a finely balanced turbine fan out, the engine will shake apart , this is why 99% of the time they shut that engine down , just glad most jets can fly on an engine down unless its a single jet , then its clean pants time
 
Yeah, a normal sized multirotor is going to destroy the engine, but the point I was making is that this is common and that they are designed to lose motors. A 15 pound goose is not going to do more damage to it as when the bird impact it breaks parts that are just as hard as a multirotor and they grind the same. Unless you have a swarm of multirotors that break more than just the engines(you can glide to a landing) you will not take down a jet. The most effective impact would probably be with a sensor and not an engine. The chance of a strike is even less likely, most bird strikes happen during takeoff or landings and are usually no big deal. Now the power of a bird strike is unreal, I've seen some that looked like you ran a car into the front or wing hahaha.

Who wants to be a passenger on a plane with anything flying into the motor that shouldn't?..just saying.

Tests are typically under controlled conditions expecting a certain range of results...Some people die in a 30mph car crash while some people dont.

A stationary jet engine is different from one traveling at over 120mph on take off or well over 200mph flying at crusing speed where it doesnt take much to do damage from an object.

A deer can run into the grill of your parked car and do "some" damage... Now hit one at 60mph and see how much that damage increases.

A quad can be hoovering in the air and get hit by the plane at 230mph or a quad can be going 230mph ,which isnt possible but, the outcome would be the same...figure out what the force would be of a even a 1/4 pound quadcopter traveling at 230 mph making impact...Do you not think its enough to damage a jet engine?..i certainly do.

Rather a plane can fly on 2 or 3 of its 4 engines,would you want to be a passenger on that plane and have that happen based on an irresponsible quad flyer?..I certainly wouldnt.
 
So Virgina Tech's test has found that the impact of a 8lb drone is "consistent with the type of damage that occurs regularly with a ingestion of a large bird."

Now would I be thrilled to be in jet when a drone flew into the engine causing that kind of damage, not really. Though it would be the same as if a large bird flew into the engine which Virgina Tech mentioned happens regularly.

So the conclusion is that while it would make for an exciting flight, there is as much danger of crashing from a drone collision as from a large bird collision. The only difference is that the bird was not piloted by someone, and therefore probably would not have the airline looking for reparations for the collision.

The point is that even at peek speed in a flight the quad will do no more damage than the ever so present bird strikes. You really should see an F16 that has hit a bird hahaha (pretty messy). Whether you hit a quad or a pigeon the end result is the same.

^This was saved as a draft I forgot to post it hahaha


The UAV is a lot less likely to impact the craft as there are so few of them, if we just educated people in the current laws we'd probably not need new ones.
