Thanks for pointing that out, I had no idea at all, really, totally clueless !!!

I really think some need to pull their collective heads in on not just this thread but the forum as a whole ! The amount of chest beating going on at the moment is ridiculous, and many of us have been around long enough on this site to understand each other, where they are coming from and their knowledge base to not feel the need to point out the obvious.

We have also been around long enough to know this very discussion has been had numerous times over the years as well

Anyway onward and upward......

As discovered on the AWD build where very little production design or engineering was budgeted. The powers that be anticipating a simple "build to print" were somewhats shocked by the result, even though I was there when this very thing was brought up at CDR and relayed to them.

Just quick question, after the working drawing are done are all designs validated by tank testing and can submarines designs be also tested in a tank to give an idea on flow noises?

a lot of the acoustic amplification is not generated by the hull - which is why subs get put into the chook shed...

Not sure what you mean by chook shed, but with all that wire only thing I can think of is a faraday cage, I doubt you mean that.

its an acoustic array which the sub is driven into and then everything is mapped - engines running, engines off etc...

its one of the unsung technologies where an australian company also developed a portable version which was 1/10th of the cost of the fixed version and within 5% of the margin of error

they look like a famers woolshed with all the sheeting and cladding missing

Video released by Pongo Airlines of their embarked Tiger ARH FOCFT in HMAS CANBERRA.

Some interesting scenery and detail scattered through the video.

Great video there.

@2.53the pylon of the ARH seems to have quite a significant amount of scratches.. Could anyone point out what could be associated with this type of wear and tear?

Interesting, seeing the tiger rotors fold manually. Much easier than the Chinooks. I think the scratches are from getting into and out of the aircraft.

My guess would be surface damage from launches ?

What a pain to fold the rotors !! Bring on the Z's at least they have a semiautomatic folding blade capability designed for operation on LHD's

Cheers

Has there been an issue with Canberra of late?

Has she returned to Sydney very early in what was supposed to be six weeks at sea?

I have seen a sketchy report elsewhere that I have not seen backed up.
