Nice Blades

One looks very expensive and difficult to maintain, the other is an aircraft engine component...
Have you got one without the bird in it? She upsets the balance.
Looks like the guy behind hasn't realised the blades aren't spinning just yet.
But on a serious note - I watched a programme the other day in which those clever chaps from Rolls Royce are 'growing' their own metallic parts - absolutely fantastic stuff!
No way she'd pass the frozen chicken test
purist 😆 😆
nice guns
Leg end you must be the only other person that ive heard mention the frozen chicken test ,
My uncle used to work for BA but thought he was leg pulling
Stuart - he wouldn't have just been leg pulling, they use the whole bird.
😉
Take a leg and pullet?
The 'frozen chicken' story was always an urban myth, far as I knew. Is there any truth in it, anyone know? (The 'frozen' mistake, I mean)
Yes. We have a farm near Nottingham that breeds birds for it.
edit: ah sorry. Dunno if that one's frozen.
My father worked at Handley Page and was responsible for designing a high velocity cannon for launching chickens at planes to simulate bird strike damage.
The chicken isn't frozen. Birds at 40,000 feet might be cold, but they're not solid blocks of ice!
Though urban myth has it that French engineers who used the chicken gun to test TGV windscreens were concerned that no drivers would ever survive a bird strike until Rolls Royce engineers pointed that out. 😀
Nah, the French engineers couldn't fire the gun. They just put it down and ran off.
The germans did the test then.
have you ever seen a chicken at 40,000ft to prove your point?
😉
The story was that, when designing the APT, British Rail borrowed Rolls Royce's chicken cannon to test the strength of their windscreens. After several unsuccessful tests, they asked RR's engineers for advice - they looked at everything and said "you need to defrost the chickens first".
Aah, sorry to the cheese eating surrender monkies. My bad.
That's the urban myth, yes, or a version of it.
"How do you test for bird strike"
"We use frozen chickens"
later ...
"We tried the frozen chicken test, they demolished our engines at shockingly low speeds, what gives?"
"have you considered defrosting them first?"
I've seen it variously attributed to BAE, Rolls Royce etc, which makes me wonder if at some point it wasn't actually made up.
You should never let the truth get in the way of a good story.
Oh sure. I just like to know when it's a story. Doesn't mean I enjoy it any less.
I like to know how magic works. Doesn't mean I appreciate a well executed trick any less. Often, it's quite the opposite.
Those turbine blades are things of sublime beauty! I'd love a blade mounted on a polished block of wood just as a work of art to display, a smaller blade, obviously. 😀
This is all fine and well... still doesn't answer the question of would she pass the chicken test or not though?!

I was thinking of the curvier, sexy looking ones, that one's a bit... mundane looking. Cheers, anyway, and I hadn't actually thought of eBay.
Actually, a search threw up a pic from the cold war jets thread on here that piedi di formaggio posted up:

That I like! 😀

Well, not much meat on the wings, but the breast and drumstick look pretty tasty...
Well, someone had to...
Urban myth or not, our engineering lecturer used it to good effect when we started, it always stuck in my mind that clarity of instruction is key.
My dad used to know a pathologist who instructed students on a corpse. He'd shove a digit in an orifice and then instruct them to lick it. He did it using one hand for the insertion and one for the licking.............clarity, very important.

I keep the intake turbine from a CAT 3208 diesel turbocharger as a paperweight on my desk. That [i]is[/i] a thing of beauty, and brings back fond memories of when I could afford to have the rest of the boat that went with it!
That you tube vid above was filmed across the road from my house. It gets ****ing tedious listening to that, or destruction testing (revving nuts of it till it stops working) whilst trying to sleep after a night shift.
Luckily they seemed to have stopped testing.
where do you live mildred?
At least she managed to keep her kit on for that photo.

I've heard that story, too - although it was a doctor and a glass of urine. Makes me think it's probably an urban myth, too...
[shakeshead]On the day that Queen Kate is photographed with the corgis out somebody post a picture of her stood next to a jet engine.[/shakeshead]
I'm off to look at some French gossip mags whilst tutting about invasion of privacy.
The version I heard has it that the worried Boeing engineers sent an SOS to British Aerospace and the next day they received a typically laconic British reply in three simple words: "Defrost The Chicken."
Makes a good yarn though.
where do you live mildred?

Just going back to that test video for a moment, check out how much the blade bends when the bird hits it.

They're fan blades. Turbine blades are, errr, in the turbine.

Test facilities shut down a few years back, a deal with the local council for the new building on the site, that and some state in the US was willing to pay for a new test facility to be built.
Guess where I work? 😀
A nice little requirement from military aircraft requirements;
(d) Liquidized remains of impacted birds shall not
penetrate into the cockpit.
Hatfield Poly used to have a development Jetstream or HS125 fuselage with a big dent above the cockpit windows from bird strike testing.
Considering that all the avionics and cockpit airconditioning services are supplied by bleed air from the engines compressor, the "no dead animal parts to reach the cockpit" requirement is actually quite difficult to engineer......... 😉
Got a turbine blade from the RR RB199 Tornado engine as a key ring which is pretty cool.
