Angus, consider however that the 190 wing came off as easily as the 109's did, only it came off in 1 piece (the entire wing came off, I am guessing the fuselage was put on a truss or something), and a replacement could be bolted on quickly. The damaged one would be scrapped, canibalized, or sent back to the factory, going by other accounts I've heard during the war.

Pulled out on one side?
It goes "through" the underside of the fuselage, so it just makes me wonder.
The 109 solution is blimming marvelous though...
It was very interesting to carry out the flight trials at Rechlin with the Spitfire and the Hurricane. Both types are very simple to fly compared to our aircraft, and childishly easy to take-off and land. (Werner Mölders)

Well, that solves that then!

Where are the bolt holes Milo?

How do they put that Girder together?

Show two preceding pages if your going to be honest.

All the best,

There are other means of assembly besides nuts and bolts.

I don't care what the 2 preceding pages have on them. You post them because I don't have them.

The spar was assembled from 7 individual pieces.

So much for Crumpp's claim of one continous piece.

No, it is the FW-190 spar, Storch.  Same one your saw,  You just saw it as it comes from Focke Wulf.  

Milo should probably learn something about Girder construction.  Most Girders are assembled from pieces and fused together.

Where are those bolt holes again?

Milo has found the parts which are assembled at the factory once they are together you are not getting them apart without a cutting torch or saw.

My supposed deceit:

The FW-190's is one solid piece running throughout most of the wing. It is not bolted together or fitted from the fuselage. The wings run under the fuselage and the main spar is one continous piece.


Stands as a true statement.

All the best,

Crumpp

Well that settles it. I'm convinced.
 It is obvious that the wing spar was engineered per specs submitted by Hall and Gillies so that when Grumman copied the FW the spar would be ready-made for implementing folding wings.  ;)

So, it isn't a solid spar at all. Doesn't matter how it's PUT TOGETHER, it's put together from several pieces to form a continous piece.
Point is, it has joints. punktum.

Angus: Re wing removal: The wing is 1 piece, and the fuselage, like a 109, has its own "belly", so that it's got its own skin and structure. However, the 190 has a trench cut into it where the spar stretches through the fuselage, and it literally drops out the bottom when unbolted, and another can be bolted into place. I did a quick google search but couldn't find an image. Those folks that are building the new Fw190s (the "190s-that-arent-really-190s") had a good image with the wing beside the fuselage, but they must have taken the image down.

Re: wing spar

The argument was that the spar was solid, and could not be repaired or replaced in the field. The fact that (at the steel mill) this thing was formed from separate smaller pieces doesn't mean much. You still can't replace or repair it.

It's like a ship's hull. *THAT* is made from lots of smaller pieces, but it's 1 big piece where you can't just swap out parts if they get broken.

EDIT: Here's an example of just the wings (not sitting next to the fuselage like I wanted to show, however).

That's cool. Nice Krusty. Do you have a seperate pic of the fuselage?
Doesn't exactly run through the fuselage though (like the a6m, - I think), and with 1 wing damaged, you'll have to take the pair off.
Still, the 109 solution is quite good.
But Crumpp's point was definately a solid spar all the way, not joined at all. I understand that as "not joined at all" , and it boggled me, for it would be worse from the viewpoint of manufacture, although buing strength instead.
Anyway, the final line is that the spar was indeed combined from several pieces. IMHO it doesn't make it any worse, (rather better), much more logical really. And whether it was bolted, riveted, welded, pressed or whatever doesn't really matter. Well, with still 7 pieces, I'd use bolts probably.
Maintenace.....

What difference does any of this make besides scoring points in petty personal conflicts?

Was only continuous after assembly, just like the Zeke.

For the Zeke "the entire wing-together with integral fore fuselage section-must be replaced" if damaged.

Just another of your not being able to express yourself correctly Crumpp.
