Was it to fly with its wings as swept back as that? A smooth ride at low level, yes. But also crash prone surely?
PaulMM (Overscan) said:Nope, sweeping the wings all the way back to 90 degrees turning you to a lifting body was a 'thing' for a while. This model locates the pivots outboard to make it work.

TomS just pointed this one out from my verbal description in the oblique wing thread. There used to be a 1/48th scale (probably) model of this atop a cupboard in the flight controls office at BAE Systems Rochester. It had definitely been there since the GEC/GEC-Marconi Avionics days, and potentially all the way back to Elliott Avionics. It disappeared one weekend during some renovations (around about the millennium?) and hopefully it ended up in the Rochester Archives, not the skip, but I don't know.Also found at NTRS -timeframe (1966) suggest that it was LAMP-AMP-AMPSS program related. My previous thoughts of TFX were re-thought
Too late and unusual for TFX. Beat me if I'm wrong.
Yes. Absolutely that one. Glad to see my memory has stood the test of time!This one perhaps ? The rightmost two images . . .
cheers,
Robin.
My model that I got made of this designMy dear Flateric sent it before,but a clearer view;

The article talks at some length about the B-1B airframe that was taken from storage.
If you're asking about what airframes were placed in storage before, here is AMARC's inventory page for the B-1B:

It's hard to believe that scanning a physical object is the best way to build a digital model that will be used to understand the condition of the fleet. Each individual part differs from other examples within whatever tolerances were in effect when the part was produced. I'd think that it would be far better to work from the drawings, which include tolerencing representative of all examples and don't require disassembly.

Do they have the drawings? What condition are they in? What file format did they use? Is the CAD package still in existence? Do you know how long it takes to go from a drawing to a 3D printable model?

Scan output is a plot file that most software convert in a single surface file. You can easily 3D print that file directly if the model is suitable for the print process.
3d modeling from manufacturing drawings can be extensive with design evolution not always documented (various contractors manufacturing a single part through time for example).
Time needed greatly vary from a multi-parts per day to a week or more for a single part.
Often you'd need to re-invent the part trying to figure what exactly the process was and what are the compatible tolerances; that whithin a very short time. If you are serious, there can be a lot of documenting and FEA to match the part on hand.
It works well only if the project leaders has a real knowledge of what this work involves. Sadly, too often, this work can be outsourced to contractors selected on the best offer per lots, leaving very few margins to do a proper work.
Agile billing is often needed but not quite well understood by the actors in presence.
But the scan output is a single file: there is no segegrated nuts, bolts, rivets, panels, ribs etc... All is blended into a single 3d model and you need to reconstruct what will be needed for you to use (interfaces, part that have an impact in your simulation, thickness of elements etc...).
Scanning is not a shortcut to design. It's a first step.

That part slipped through my mind in my attempt to put everything on the text. You are right... And, if that was not obvious in my reply, they do know absolutely what they are doing.But the scan output is a single file: there is no segegrated nuts, bolts, rivets, panels, ribs etc...

From the article, "Once the B-1B arrives at NIAR, researchers will 3D scan each part, "down to the nuts and bolts," to create a highly detailed virtual model that they can reassemble and disassemble at will on a computer."
They're going to tear it apart. Just waving a hand scanner over an assembled airplane would be useless. And nobody said it was a, "short cut to design". The design already exists. It IS however a much more efficient way than wading through a warehouse full of drawings and trying to update that mess to current CAD technology.

They might even use a library of modeled objects to cross reference the scan data and detect if a shape match the projection of a known part.
