They were used to verify the fit of everything from hydraulic tubing and fuel lines to control cable and control rod lengths. You would also have sub-element mockups for things like cockpit furnishings. This was back in the day when aircraft shapes were lofted like boats and the drawings were created on vellums with pencil. Not as accurate as 3D modeling now, so everything had to be checked before you made up fixtures for manufacturing. A lot of tubing and such was developed right on the mockup and then copied for production.JDK wrote:And a question. It seems clear that Grumman was particularly wedded to the idea of the mockup, presumably pre-production. I can see that made sense to convince the Navy in the locust years of the 30s, but in the 40s, even before Pearl Harbor?
And what use where they? I know the reasons normally advanced, but a lot of it looks more like a company demonstration model to impress customers (see the quality of work, and finish of the pieces) rather than a 'see it all fits' kind of tool.
