Results of damage testing

[Guest Glenn]

It seems the US Federal Aviation Administration (FAA) has a unique device for testing the strength of windshields on airplanes. The device is a gun that launches a dead chicken at a plane's windshield at approximately the speed the plane flies.The theory is that if the windshield doesn't crack from the carcass impact, it'll survive a real collision with a bird during flight. It seems the British were very interested in this and wanted to test a windshield on a brand new, speedy locomotive they're developing.

 

They borrowed the FAA's chicken launcher, loaded the chicken and fired. The ballistic chicken shattered the windshield, went through the engineer's chair, broke an instrument panel and embedded itself in the back wall of the engine cab. The British were stunned and asked the FAA to recheck the test to see if everything was done correctly.

 

The FAA reviewed the test thoroughly and had one recommendation: "Use a thawed chicken."

The show "Mythbusters" did this. Yes a frozen chicken will go through the windshield more than a thawed one. Whoever heard of a flying frozen bird. However not long ago someone was firing chickens using a slingshot or something in Sydney.

They also do this when certifying a new (aircraft) engine.

 

After firing the (thawed) chicken into the intake of the engine, you must be able to shut the engine down in the normal manner, without any blades separating.

One way to chop up your chicken for dinner :?

 

 

[Guest Guest]

Certainly is. :lol: :lol: :lol:

 

They don't care about the chooks, but the engine must still operate long enough to be shutdown normally, and there can be as much damage as they like, as long as a blade doesn't actually separate from the engine. :shock:

i had a video on my pc not long ago, from Pratt and whitney, showing testing of bird ingree , they fired hundreds of birds into the engines at different speeds, different engine speeds, and at all different areas of the turbire, even inti the low pressure compressor intake! and the engine had to run for a set amount of time at maximum power after the ingres. it was an interesting video, all filmed at high speed, in some cases the bird would strike as many as 10 blades before finally getting sliced enought to go through!
