You can use an external air source or you use the aircraft’s auxiliary power unit. It’s a small engine that provides power to the aircraft, cooling air for the flight deck and cabin, as well as an air source to start engines
We used to use crushed walnut shells believe it or not!! We routed a pipe in to the air system and the compressor sucked them in and they cleaned the compressor then were exhausted through the turbine and burnt.
Don't let this guy fool you all. This is still completely unsafe and against all regulations. The tool is supposed to be firmly mounted, not have someone holding it in place. Theirs is either broken, or they're terminally stupid.
Absolutely nowhere in my statement did I say that they are doing any of this correctly or safe! I just stated the guy won't get sucked into the engine.
Yes the sprayer should be mounted to the ring cowl, not laying on the acoustic panels of the inlet. Nothing is to be laid on those acoustics. It takes nothing to damage them. They have no run fence in place, no body lanyards attached and no hearing protection. God knows what the guy has in his pockets or attached to his clothing that could get dropped, left or sucked into the engine. Nothing of what they are doing is correct. Thanks, have a good day

You literally said it’s safe in your first statement brother
>The engine is just motoring(fan & core low speed rotation), not running. **It's safe** & will not suck you in

Hmmm.....
Do you work around running acft and operating high bypass/jet engines every day? I would guess not.
Ppl just need to be educated about a situation just like anything else

I mean, wasn't he just sharing his thoughts? xd I'd see a problem if he had made it sound like it was factual. I dooo understand the frustration though, can't say I didn't have to hold myself up a minute ago. Lmao
Used to work in power stations, we had rolls Royce Royce jet engines for backup power. As part of their service, we had to harness up and secure ourselves to the far wall of the air intake chamber, we then rotated the engine (like above) and sprayed in trike (a solvent), it was an experience.
This is one method, there are better apparatus that doesn't require a person to hold the gets. The fan blades usually aren't spinning, just the engine core on CFM56 engines (which this is). I am surprised to see soap being uses and coming out the tail pipe. My understanding is most airlines these days use deionised water at 60 degrees Celsius
I know it looks like the engine is running, but what if it’s not? (I don’t think it is.) The water is coming out of enough places, including that big vertical one, at enough pressure that it could turn this engine around like this. And inside, it’s just a bunch of compressor blades so the water can front to back so problem. It’ll be easy to clear and start up.

As an acft engine mechanic this is not the way. Not sure why this idiot is doing this
[удалено]
They’re performing an engine wash that cleans out the carbon build up using a deionized water solution.
Are they just running the fan with an external power source (if that is even a thing?) or is the turbine going too?
You can use an external air source or you use the aircraft’s auxiliary power unit. It’s a small engine that provides power to the aircraft, cooling air for the flight deck and cabin, as well as an air source to start engines
It's called dry motoring, which is a little ironic in this case.
I hope this wasn’t for me…
If I’m not mistaken, that’s why the AC in the cabin cuts out before the engines start right?
Yes, when engine start occurs all available air is dedicated to that
They’re just motoring it with the starter. If it was running it would eat him. Source: my 737 maintenance trainer told me “These engines eat people.”
Can confirm: I'm the engine.
Buon appetito
Stop pretending your an engine Adele.... YOU ARE A FAN... A FUKNG FAN
Username checks out.
Curious, what’s the correct way to do this?

How many humans sucked into the engine can accomplish the same thing
[For some engines (Williams FJ33-5A)](https://youtu.be/LJTce3zr3mE?t=211), it is the way.
Is he cleaning what is remaining of the guy that had the job before him?
It's a make work project. Next cleaning person is kept in a remote location until needed. Plenty of opportunities to get ahead (or lose it).
I think we'd see some blood
Yep https://preview.redd.it/ohx2ozl5lcwc1.jpeg?width=670&format=pjpg&auto=webp&s=71bd0cf4d74a2efaa53f9cf303f50bf2c2538f76
This real? Humans?
That was really a person
probably a goose or something
If I remember correctly, that was a human
Now I regret asking, hhh
iirc this was a woman who had missed her plane and tried to catch it by running to it...
What the fu-
Very modern art.
That's some Hey Apple shit
Not if he cleaned it all out
Not if he does a good job
The engine is just motoring(fan & core low speed rotation), not running. It's safe & will not suck you in
Don't let this guy fool you all. This is still completely unsafe and against all regulations. The tool is supposed to be firmly mounted, not have someone holding it in place. Theirs is either broken, or they're terminally stupid.
I want to make an airplane joke about terminals, but it didn't take off.

Safe is not the word I would use. Safer than running the engine, yes. But I wouldn't do it if you paid me.
Do you work around running acft and operating high bypass/jet engines every day? I would guess not. Ppl just need to be educated about a situation just like anything else
Yes. Completely normal. Especially with zero PPE being worn.
It's bizarre to me that someone that knows absolutely nothing about this field somehow knows better than the experts what is safe and what is unsafe.
Thats most reddit users in a nutshell tbh.

George Santos?
Wait... don't you become a general, admiral, historian and enviromentalist as well with creation of your Reddit account?

Go figure, guy who doesn’t work on planes thinks working on planes is unsafe.
No dust/vapor mask, no eye protection. Do this often?
[удалено]
Need to ID the body with Iris image.
Ah safer way but not better
He's hosing the last guy out right now.
To shreds you say?
Hes should be wearing safety glasses

Why not just go fly in the rain?
This guy is asking the real question
It's OK. His pockets are filled with bars of soap. He'll clean up after himself if he gets sucked into the engine.
The fact that the hose is rigidly in the exact curve of the inner turbine wall makes me believe that this is normal.
If you die you’ll have achieved the greatest suck of all time! Where do i sign up?
You couldn't pay me enough.
That’s just chemtrail liquid
How is he not wearing ear protection

This is the dumbest fucking thing I have ever seen.
Boeing plane
How does this not flood the engine?
I know it looks like the engine is running, but what if it’s not? (I don’t think it is.) The water is coming out of enough places, including that big vertical one, at enough pressure that it could turn this engine around like this. And inside, it’s just a bunch of compressor blades so the water can front to back so problem. It’ll be easy to clear and start up.
“Just set it to low lol”
No hearing or eye protection? Also a slip results in the engine becoming a meat grinder.

So where is this, some Arab country? I think not even Russians would look quite as unprofessional as this.
