any fibrous panel composite is worthless in compression, the only thing that can resist compression forces in a panel type fibrous composite is the matrix. and the matrix has a small resistance to compression.
As long as the forces are planar there will be little risk of delamination. this is probably the reason that its used where it is, the forces will be trasmitted along the material.
force direction means allot in composites.
that article sounds like airbus think boeing havnt done their homework on composites. in reality both companies have a relatively long experience and exapnsive knowledge of composites. They also have the right tools to analyse the problem.
composites are relatively new in the manufacturing world, in the scales we are talking about here, so things like the fracture mechanics of all the different lay-ups and the all the different materials is going to be junior to alloys….but its advancing quickly.
there is a substantial field for things like modelling escape procedures and exits. these things include a factor for human randomness under pressure…statistics is good for somthing after all!!
airbus are right that it is likely that someone would be injured during emergency evac procedures given the height of the upper row of emergency doors. But i suppose that prevention of injury is a lame excuse for not testing these things.
does anyone have any information on the validity of emergency escape tests and the frequency with which these systems are used???

lol yes thats right the stubs are both handed the same, thankyou for the trivia warbird!
thanx
lol yup, but…..nope thats not the irregularity….:)
they are countermeasure dispensers.
well the one with what looks like guys hanging out the side door, i think is the falcons aircraft.
the other was used in the tactical herc display.
steve, the ceiling might not be up to the job to of hanging it 🙂
nice photo’s!
good to see its not a permanent fixture there.
would love to go see that ar234.
coanda
matt, yes should have done but didnt have time, these are hot off the press!
kodak, there is a hump in the runay, but i think i was holding the camera a bit on the wonk.
coanda
thanx a-29!
excellent piccies!
do you have a press pass or somthing to get a chance to take some of those photo’s??
i’ll be there!!
the meteor and vampire pair arrived, did there ‘thang’ and disappeared off again, lots of aircraft doing hte rounds today!
air atlantique have got a good thing going for them there. the twin pin and the dak were at cosford today both looked full.

i suppose many of those comments are from people who wouldnt go near airshows usually, but of course airshows these days HAVE to be billed as family events.
I understand that a family in tow isnt the easiest thing, my dad used to have to do it with me, my bro and sister too! imagine paying attention to whats going on and looking after three kids. I understand that its not easy.
I am not having a go at anyone and have watched cosford airshow from the inside and the outside in the past (particularly when you HAD to pay for the museum too (which is an admirable organisation but having been there a number of times, that particular cost wears a bit thin)).
tickets may have been sold out at one outlet, but, there are others.
because this is a ‘family'(with reasonably priced ‘family tickets’) day with many people i suspect not even particulalry going for the airshow, I would expect people to show a lot less patience. Queues are a fact of airshow life, they happen everywhere to everyone. I have been going to airshows as a nipper and on my own for the past 22 years(dad took me to woodford when i was months old! ) and of course we have got stuck in traffic, we never made it to abingdon when they had the huge flypast, but were stuck on the motorway and had to live with a look round cambridge( VV boring for 3 kids under 10!!).
the answer???
there are two answers.
fly in.
go to bed early and get up early.
we live in that area and have got up early enuf for all sorts of shows all over the place.
Unfortunately for cosford there is only one practical way in and out, and thats down the road there. there is a fire exit that they usually let some traffic out of, but thats on the active side of the field.
I heard over the tannoy that the nimrod had operational commitments.
canberra and sentry?? are there even any in this country right now??? pretty busy I’d say. the sentry has not made public displays to my knowledge, outside of waddington.
as for a SAR display, did you miss the big yellow helicopter???
rotary cfs(and the other units at shawbury) has more important things to do than get a display team going.
raf at home day?? i’d say so. a good turn out from the raf.
I admit that it would be good to see an apache display. i went to larkhill last summer and saw it display there ,and it was rather good. and there was one in static, which is somthing considering the ‘situation’ with them right now.
now, besides the UAS and attached AEF, it is an army camp I believe. A signals unit.
coanda
nope, but from those photos, and considering the display was ‘on’ you walked right past where I was standing
what did you think of the event?
coanda
well given ther return from a small set of objects like that, it’ll still probably be 80% signature effective. especially if the missisles are ‘treated’ and the pylons are built properly.
