Dropped into a turbine engine

Hey! You found the original.

Rare opportunity to demonstrate a sound that no turbine tech wants to hear... ever!

... because it means you have to get that thing you dropped in there back out. Jet engines are heavy and sensitive, so it's a big deal to lift one up and turn it over, just to hopefully drop out a small piece that some dumbass dropped in there.
If that does not work, the engine must be disassembled to the point where the item can be retrieved. This will be an expensive process.
... that's why it's a bad sound.

Shot in summer 2010 with a Canon Power Shot SD980is, at its max setting of 720P and 30 fps.
It was a 275.00 camera then.

This article/instrument is the compressor section of an LM1500, which is the ground running version of the mighty J79 turbojet. It is sitting with the inlet facing down, so the blades get bigger the lower you get, making the notes or sounds get lower in frequency as the screw drops through.

The blades are normally mounted with some looseness, to allow for thermal expansion, and to absorb vibratory/resonant energy.
These blades have built up corrosion in their mounting slots, and are seized solid, so they ring out like tuning forks.
If blades in this condition were to be run in an engine, the ringing and resonance would quickly build to the point where they would crack and break off, totally destroying the engine.

This actual piece of an engine has been turned into a public display and art piece, called the Turbinophone. Google that, and enjoy!
The Turbinophone is mounted inlet up, so the notes rise in progression as pellets are dropped into it.

If you want to hear an experimental dubstep composition using this sound, check out "Ghost Turbine" by Skenik on YouTube

He has also made one using the sound of the starter for a Rolls Royce Olympus engine from another of my videos. It's called Kiryu Lab

Oh, and please don't post links to the ripped off versions of my video.

Finally, a proper video on sounds that shouldn't be coming out of turbine engines

[austinhall]

As a mechanic for 8 years, the second you held the screw over the drop zone I immediately got goosebumps and anxiety.

[RedKincaid]

I don't know why, but I come back to this video every couple of months. Been doing it for the better part of a decade by now and don't intend to stop

"The terrible sound you never want to hear"

[anarghyasumanth]

Imagine being a pilot and hearing cool music coming from both sides

[liorshalmay]

damm this engine can have a second life as a musical instrument

[pixelnaut]

That sound is insultingly whimsical for something you don't want to hear.
