fuselage parts
(OP)
I have a client who needs to perform bird strike testing. We did design work for them and now we are going to help them coordinate the bird strike test. Where do you buy fuselage parts for testing? I am in need of an A320 fuselage.

i'd talk to airbus (to find out who's scrapping hulls), or google "used airbus parts"

Airbus should be able to advise where their bird-test facilities/cockpits/vendors are located.
Most transparancy/windshield manufacturers will have [or know where to go for] cockpits used in birdstrike tests. Find out wwhich company makes AirBuss A320 windshields.
NOTE. IF You are testing new windows/windshields and/or heaters these vendors may clam-up. IF installing new antennas or sensors [IR,UV, low-light, mircrowave, etc] on the cockpit or nose, then probably no problem with any of the transparency vendors cooperating.

must be a big antenna if you're worried about bird strike ?

There have been many cases where large birds penetrated the nose skins/substructure, or pressure bulkhead [after penetrating the radome and radar]... and the crew gets showered with "soft/foamy/feathery" debris.
I would imagine that hail and lightning strikes could also be a significant problem.

RE: fuselage parts
Reason for this is simple: acft fly at +body-angle of attack [nose up] at low altitudes, low airspeeds, so that the crown areas are "shaded" from bird strikes by the cockpit.
low altitudes = typical range for large birds.
Low air speeds = Typical operation environments at low altitude controlled airspace
Upper crown strikes could only occur at low altitudes, high airspeeds, when body angle of attack is "0" or below (-)0 [nose down].
An example of this might be the Navy P-8 [based on 737]: aircraft is flown at low level and relatively high airspeeds over the ocean during it's maritime surveillance mission.
Obviously lower body [belly] installations are more vulnerable that upper crown installations [except lightning and hail].
Has this aspect been discussed/evaluated with Your client?

RE: fuselage parts
i'd suggest designing a blow-out panel to prevent over-pressurisation of the radome if/when punctured by a bird
pls, let me know when you do the test ! or at least post video !!

We have an A320 fwd fuselage and I'm pretty sure that's where we got it.

RE: fuselage parts
Improper installation/mod, mechanical [hail, maintenance stand, etc], corrosion, fatigue or lightning damage would be 99.9999% reasons for crown antenna/radome damage/failures.
Bird strike? Doubtful: unless there is an aspect exposed in typical flight attitudes where birds could be realistically encountered, such as far forward, high crown. A tall blade could be an exception.
Ice-shedding, hail strikes, corona arcing, etc at cruise attitudes are more likely than bird strikes.
In this case keep the quail frozen

RE: fuselage parts
it might well not be likely, ice acreation and (possibly more imporant) ice shedding are other concerns, but you need to have an answer when they ask "and what happens if a bird strike happens ? how do you demonstrate compliance with 25.571e(1) ?" saying "it shouldn't happen" won't get you far.
i'm curious that this is for "an antenna under a "large" radome" ? is the concern that the bird will puncture the radome, and then impact the antenna with sufficent force to damage the fuselage under the antenna ? that sounds a little far fetched to me (possibly "extremely improbable") ... and Very hard to show on test; you need to get the bird to hit the antenna ? i know some bird strike tests show unexpected results ... once, firing a bird at a wing/fueslage fairing, the damned thing punctured the fairing (as expected) but then broke a small fuel pipe buried under some structure (for protection !) .... i reckon you can never predic where the bird will go, except that it'll go where you don't want to !

I tried boneyard2u - he doesn't tear down the airframes so he doesn't have it. Keep trying!
RE: fuselage parts
instead of testing, i'd've thought you'd get some milage from a NL FEA ?

NW used to tear down their old aircraft at Laurinburg, NC airport. Don't know if that operation still exists after the merger with Delta.
RE: fuselage parts
Does it have to be an A320?
