I'm guessing the myth in qustion is about the frozen vs non-frozen
chickens.* It will be interesting to see what the Mythbusters guys do

it.

Watched the program.
Their conclusion, frozen or thawed makes no difference to impact.
Strictly a function of mass, velocity, and time of deceleration.


Hmmm, I suspect when dealing with a kg of water it makes a
big difference to the fan blades if that water is frozen
in a single lump.

Maybe in the case of water. But I once talked to an engineer involved
in developing the canopy for the Shorts Tucano and he basically said
the same thing - frozen chicken, thawed chicken, made no difference to
the damage caused.

IIRC he said it was a 4lb chicken that was used as standard.

It was interesting the extraordinary damage a 100MPH chicken
caused to that little Beechcraft. It looked like a 20mm hit.

Heh... maybe they need to design for pigeon strikes and not chickens.
Really... when
was the last time you saw a chicken in flight higher than 20 feet off the
ground, or
hanging around an airport? Pigeons and gulls on the other hand, or ducks...
they get up there
a bit more. But are much smaller birds. Unless the goal is to design for
collisions with canada
geese (our secret weapons).

Bird strikes happen near the ground as well as at altitude.

A structure that will take the impact of a larger bird will take a
smaller bird in stride.

Pretty much. In fact, the size bird for the F-16 canopy tests was
upped from 'chicken' to 'turkey' after a collision with a California
condor.

They also have at least one at Lockheed Fort Worth (for testing

The one I saw was portable and was installed in the transonic wind
tunnels when they were testing full scale windshields and how they
reacted to bird impacts at high speeds.

Took a field trip to Tullahoma once (Arnold?) and saw the gun too.
According to the folks there at the time (1995), they get live chickens and
euthanize under the supervision of the local ASPCA immediately before they
get shot out of the gun and into the unsuspecting canopy/engine. The whole
process is precisely controlled and monitored.

Hell, I've built them. Its not that hard to make a pneumatic cannon.
There's
even a sport for them (google search "pumpkin chucking")
