I went digging through my archives and came up with these C-47 photos from Vietnam. They are provided for interest only and probably have little value.
|Back to business. When we left off last month you were
ready to start the wings. Here are the numbers you will need:
C-47 Wing Butt Lines (These begin new at Fuselage Butt Line 142.00
|Ok, here comes a problem. Notice that the wing is flat out
to the engine but then it angles up a bit. This is called Dihedral and
is a common AC design feature. To plot this we need a new set of numbers
for the wing water lines. Guess what? Iíll have to approximate. First
the flat portion:
At FBL 0.000 and Station 195.5 to 372.5 WL 115.00
At FBL 142.00 and Station 195.5 to 372.5 WL 115.00 (The engine mounts centered on FBL 111.00).
Now the Dihedral; At WBL 413.000 and Station 312.5 to 360.0, WL 160.00.
