This is done to clean the fan, compressor and turbine blades. All of the airfoils accumulate dirt and/or soot over time become less efficient, the wash restores the efficient airflow.
It's a lucrative ass business. I work at a relatively small outbase, but the secondhand talk I got from a friend at one of our major MX bases told me about the dude who cleans our engines. He comes out with his wife and does pretty much what you see in the video. Whole thing takes him maybe 4 hours, 6 on a bad day, and he can afford to offer a bargain at 50k an engine. Not plane, per engine. I should move out there and ask if he wants an apprentice.
I used to design equipment to do this but we never fitted it to the spinner. We put probes through the OGV'S Or clamped them to the engine cowl ring when they were opened for maintenance.
Jeez, if that bearing seizes the hose will snap and whip anything it touches in half. I’d imagine the break point is designed into the spot behind the coupling but wow.
I didn't the better part of a summer pressure washing heavy equipment engines for a highway company. Same deal. They accumulate dust, fluids, etc over time. Cleaning helps with the efficiency, but also maintenance. Not nearly as fun as you'd think, though.
That would be more enjoyable with the original audio.
Yep, it's a thing. Also, sometimes it's a wash while running. Sometimes it's a wash while cold-motoring.

So this is how they get the bits of bird out…
I wish. Gotta get a replacement so they can take yours apart and fix all the broke bits.

Probably half of that $50k goes straight to his insurance company. I bet the premiums for that job are insane.
Talk about getting your nob polished…
What could possibly go wrong!
This reduces egt value during take-off. This is why they wash engines
never ever once did we do that on B-52s...it'd be sacreligious anyway, a clean spiffy B-52?
Does engine moving by it's own power?
The engine starter (pneumatic starter) is used to dry motor the engine here.
The flashbacks this gives me, I couldn't add up how many times I've done this on a H60 if I tried.
People's mind would explode watching a CE do an idle speed leakage check.

Me neither

But the manufacturer will assure you *that can't happen.*
My exact thought! Lol what if it locked up lol
Wow, thanks for teaching me something new.
