I'm curious about something: Why did we decide to use the Me-262 wing as a starting point rather than just sweep back the P-51's existing wing, thicken it and thin it where necessary, and fiddle with the area?
Where ever did you get that funny idea from ----

No doubt from the same place they all come from, a lack of knowledge and a 'conspiracy theory' view of history.
:banghead:
Prob because it already flew

When it would look remarkably like the wing from an Me262.............

I remember being told that the wing of the F-86 was based on the wing of the Me-262 with a 35-degree sweepback at the 1/4 chord with adjustments to area and aspect ratio
The didn't, the 262 and F-86 wings don't have much in common.
Let's start with the airfoils:
Aircraft Type Root Tip
Messerschmitt Me 262 Schwalbe NACA 00011-0.825-35 NACA 00009-1.1-40
North American Aviation NA-151 F-86A-1 Sabre NACA 0009.5-64 NACA 0008.5-64
And then of course the differences in construction, sweep angle etc., etc., etc ...
What they have in common is the leading edge slat type.
As to what the airfoil numbers mean:

Have fun.
BTW the P-51 airfoil was from an entirely different series.

Actually, we got a lot of aerospace research from the Germans after the war.

The bottom seems to be missing some numbers...

Actually, I was under the impression when I posted this thread that the baseline cross-section was the same with an increase in sweep: I was wrong, but I covered this.

Okay, that's what they based it on, thanks.

Leading edge slats were invented at the end of the First World War.

Yeah -- Handley-Page and another guy came up with the idea simultaneously, then both reach an amiable agreement on the pattern. Later the guy worked for Handley-Page specifically on slats and slotted flaps. The only difference the Messerschmitt slats have were they work automatically, otherwise it's an Handley-Page set-up
The Me-262's were actuated by dynamic pressure and g-load right?
