This blew my mind

Post by fatman »

I now know how they clean compressor blades on a jet engine, they throw walnut shells into it while running :shock: I was lawyas under the impression that basically anything other than air was going to kill it.

The rotating assembly of most modern gas turbines
is as a whole extremely tough.
It took a flock of geese to disable
the Airbus that crashed into the hudson last year.

What will do big time damage is metalic things like
fasteners.

If you manage to break a piece off a blade all other blades down stream are gonna catch hell.

In general organic things like birds and small mammals
will not stop an engine.

Extremely big birds like Turkeys and geese are big trouble
as are large mammals like Kangaroos and people ;-)

There was an incident at Houston Texas where a worker was injested into a Boeing 737 engine
and reduced to tiny bits. While the engine was damaged, it was shut down by the pilots.
All stuffed up with clothing and bits of Human burger it continued to run till shut down!

Word is that the tarmac behind the engine was gruesome;-(

I saw a J-57 that injested bits of a NVA SAM still running despite being so damaged
you could see light through the length of the engine after shut down.

I wonder if a jet engine could be modified to produce instant Kebap? Slab of lamb in, small grilled slivers of meat out!

I imagine it could, as long as you like the taste of kerosene with your lamb.

Produce instant Kebap?
Take a look at those photographs.
That poor bastard never knew what hit him.
He was reduced to something more like hamburger run through a blender.

YUKK.

I saw a kid go down an intake on an A-7 Corsair II running at full power one night. Saw a wheel chock get sucked up into another one. That was pretty exciting as well.

Both incidents were disastrous to the engine.

They pulled the engine and sent it to the states to remove the remains of that young man.

Walnut shells will clean the crap off the blades very nicely. They are ground very fine, like coarse saw dust.

In the USAF we called it a "Compressor Wash"
It was a slurry in water in those days.
