This is just a scale model built by someone. Nice, but it doesn't belong in this topic. That's what the Modelling Forum is for. You also already posted this exact same display of century series models earlier (which I removed).
The first attachment is the article you've referenced. It's OK.
Lift will force the air upward around the leading edge. The angle of attack of the wing is then always superior to the angle of incidence (the angle b/w the aircraft reference axis and the wing root chord). On the Blackbird, the angle of incidence is more or less zero (the wing is aligned with the main axix of the fuselage).sferrin said:Sundog said:NUSNA_Moebius said:Does anyone know why the fuselage was sort of bent/angled up as you go towards the front? Seems that the plane would have a constant very nose high attitude even at high speed and high altitude. A bent down nose like in the Su-27 (maybe not as drastic) would seem to make more sense to me, as it would smooth out airflow and allow the radar to be pitched down more.
You will notice many of the HSCT designs had this same feature. It minimizes wave drag. The F-108 was designed to cruise at supersonic speeds, the Su-27 wasn't, which is why it wouldn't be a good idea to angle the nose down like on the Su-27.
Often wondered the same thing about the Blackbird. If you raise the nose so the inlets are normal to the direction of flight (the orientation that would seem to make the most sense for a circular inlet) the nose would be high (more lift too).
IIRC, the Blackbird originally had the fuselage and nacelles aligned and it didn't work so well, so they angled the fuselage up slightly which allowed the chines to develop more lift to control the AC shift, similar to what canards would do.
This link should bring you to a video showing mockup and artwork from Boeing image archive
I can't find a way to link directly to the item page but this search result (at the moment) isolates it.

That sketch of the XF-108 next to a Blackbird really drives home just how huge the XF-108 was going to be...The first one is an artwork of mine....
That's a nice one! A MiG-31 would be a interesting addition for comparison.The first one is an artwork of mine....
It wasn't my intention, since it was conceived as "All American" interceptors...That's a nice one! A MiG-31 would be a interesting addition for comparison.
Fair enough.It wasn't my intention, since it was conceived as "All American" interceptors...
