B-1B Lifting Body Effective Area?

[IAD]

Quick question, in regards lifting bodies...

(Specifically, the B-1B Lancer's LB.)

Just how much of the surface should one consider to be 'lifting', for the sake of wing-loading calculations? Would the yellow outline (see attached) be a reasonable estimation of actual lifting area?

Thanks in advance..!

You can probably consider the area of the motors as lifting also, filling in the gap between the fuselage and wings.

With that adjustment, the above estimate would be reasonable, do you think?

Wow. Ok... The B-1B has a pretty impressive amount of wing, then...
