Re: The de Havilland Comet
#42I still think the Comet manages to look more futuristic than other civil planes. Something about the look of those engines in the wing roots with not a nacelle in sight. Such a shame it turned out to be doomed due to being first and the now well known metal fatigue story. The article, as with everything Comet related, ends with noting that lesson is why airliners now have very rounded windows. Yet none ever wonder or…

The reason why cockpit windows are so angular is of course for visibility. They are mounted in a heavy load-bearing frame. Structural efficiency is sacrificed for a better view.

Do you have a problem with any of the facts I presented?

My school was right next to a runway (as in a couple of hundred metres at most) — whenever a Nimrod was taking off, class had to stop and wait for it to do its thing as there was simply no competing with it on volume. Loud buggers! As with a lot of British war jets from the post War decades, there was something quite beautiful — almost organic — in their lines.
Concorde is still the most beautiful aircraft ever, IMO.

The Comet did go on in a military role as the Nimrod - I once saw an AEW Nimrod parked at the edge of RAF Kinloss - a staggeringly ugly beast: https://en.wikipedia.org/wiki/Hawker_Siddeley_Nimrod
They were an amazing example of a legacy system being maintained far beyond any reasonable expectation of life at gradually increasing cost, to a great extent because nobody could agree on a replacement and the one-off cost of a replacement was always a bit more than the endless "maintenance" and "refurbishment". If I remember rightly the refurbishment project hit the problem that, because the original planes were ha…

I remember seeing a Vulcan bomber doing aerobatics over our wee Scottish village - quite a site and the noise was incredible.
The noise was such that I now thoroughly believe the Brown Note might well exist, and back then was stunned to be able to imagine I could discern individual organs resonating inside of me. I've never felt such a level of bass since, not even in my later clubbing years, hugging bass bins in sweaty clubs, listening to dub techno or whatever it was that took my fancy twenty years ago... .
SUCH noise. It becomes so loud it's not even noise any more, just pressure waves and complete sensory discombobulation.

#46I wonder why all the planes were names in some variation of Yoke [name, including Yoke]? Maybe: yoke: NOUN; Irish informal; A thing whose name one cannot recall, does not know, or does not wish to specify. https://en.oxforddictionaries.com/definition/us/yoke

Hi, that's me you're insulting. Do you have a problem with any of the facts I presented?
There are many disciplines in "aerospace engineering", and if you say work on instrumentation, then saying "aerospace engineer here" in this context is about as misleading as saying "circles are just squares with large radius corners" (they are also "triangles with large radius corners").
What do you actually do in our job?

I have a problem with every statement you made in your first reply, starting with "aerospace engineer here", which implies you are specially qualified to discuss airplane structural design. There are many disciplines in "aerospace engineering", and if you say work on instrumentation, then saying "aerospace engineer here" in this context is about as misleading as saying "circles are just squares with large radius corn…
I work in airworthiness and maintenance, so I deal with aerostructures on a daily basis. You?
>about as misleading as saying "circles are just squares with large radius corners"
What happens if you take a square with sides of length x, and smooth the corners down until the radius of each corner is x/2?

I know you work in airworthiness from your post history. It also indicates you work with flight systems, and not structures. Amirite? What is your professional qualification?
You can see what I do in my profile.
>What happens if you take a square with sides of length x, and smooth the corners down until the radius of each corner is x/2?
Same thing as happens with any regular polygon with sides of length x.
You said "It's not the shape of the window but the radius of the corner". This, like every other statement in your initial comment, is a misleading half truth at best. The true picture is complex, but the shape definitely matters, because you want to avoid abrupt local changes of stiffness in the direction of most stress (this can happen without any openings even, for example by adding a local bracket).

You are not quite rite, no. "Flight systems" is ill-defined but if you mean flight controls like elevators and ailerons and whatnot, then yes. I also work with structures as a routine part of maintenance, repair and overhaul. Why would you assume my HN comments are a good way to accurately determine my area of professional expertise? Most of my comments are just shitposting about javascript anyways.
>The true picture is complex, but the shape definitely matters
Of course it matters in a general context, but what matters more in the context of fatigue-related crack growth and stress concentration is the radius of the corner. This is why we stop-drill cracks. This is basic undergrad stuff.
In any case, I see from your profile you work in oil and gas. Not sure why you have so much emotional investment in this topic but this quote of yours:
>Don't listen to the "aerospace engineer" that answered you. The reason why cockpit windows are so angular is of course for visibility.
Doesn't refute or rebut anything I've written on this topic. In fact I was not attempting to explain why cockpit windows are polygonal in shape, only that the corners aren't as sharp as it might seem at first glance/long distance because it seemed like OP was equating "rectangular" with "causes structural problems".
I probably won't reply again, have a great day bro.
