Oh well there's the problem right there, the engine is spraying out flames.
E: Wow that's really burning. Any pilots know why it seems so on fire? Why didn't the fire extinguishers work?
I’m no engineer but it’s probably got something to do with the softball sized hole in the engine near the fuselage. And I think you’re right about the flames that are spraying out being part of the problem. I mean it looks cool, but it can’t be safe to fly your plane around like that.
Critically, is the hole from something punching in or out?
Most likely. Great observation.
This guy is definitely an experienced engineer. Nobody else dodges bullshit like this.
I would assume out as there aren't many frozen turkeys that far up
I'd say that's quite likely to be a turbine blade punching out, whatever the initial reason for the failure was.
not an expert either, but I dont think the hole nor the flames are supposed to be there
It depends on what causes the fire. There is a shutoff valve at the top of the pylon that should cut fuel and hydraulic lines to prevent anything combustible going into it. If the fire is caused by a fuel issue outside of that, such as a leak above the valve, the halon will not be able to extinguish it. The halon also discharges into the cowling so if the cowling is compromised it can’t extinguish it, or if the fire is inside the core or in the tailpipe it won’t make a difference. Finally, it’s designed so that in the worst case that pylon will simply burn clean off the wing leaving the rest of the plane and 3 other engines to continue flying. If I had a fire like that in a mountainous region I wouldn’t even touch the fire handle until after I get to a safe altitude. So long as the engine is producing thrust the fire spitting out behind it doesn’t really concern me that much for a short while.
Gotta love sacrificial parts
Burning, multi ton engine falling from the sky is indefinitely safer than the other 3 and the attached passanger plane coming down, but sucks to be the person it hits.
If you see a plane having issues in the sky, try to move away perpendicular to its path. If it goes down, it'll be hard to predict where it will end up since it can change direction as it dives, but anything falling off of it should generally follow its inertia. Though with thrusters, if there's even a bit of thrust still when it detaches, it can also wildly change its momentum.
Another thing to remember is that if something is falling but it doesn't look like it's moving, it's falling towards you. Again, move to the side and keep going until it looks like it is drifting to one side or another. Odds are very low that it will hit you even if you stand still, but that can help your odds if that makes you feel any better about it.
Oh, being hit by an aircraft engine is one of those thing where if it happens - sorry the universe was involved in that one. My tombstone would probably say something like "doesn't like planes as much as he used to" or "here lies most of happy camper and a turbine blade we think has a smear or two".
If it’s somewhere I need the trust for climb gradient it’s unlikely to land on anything important. A small chance of one tragedy is far better than a large chance of another.
Oh, im not being sarcastic.
Like how the mounting bolts are designed in such a way the engine falls off without taking the important parts of the wing with it - sucks to be on the receiving end but it beats the shit out of the other options.
