1. The Germans and the Americans developed the area rule interdependently, and the concepts merged after WW2.
Then how come we weren't aware of that 1943 research paper post WW2? It would seem that we weren't fully aware of area-ruling until 1952 with Richard Whitcomb's work.
The XF91 max speed was mach 1, so it was not likely an issue.
Actually, the XP-92/XP-92A and XF-91 were both designed to have supersonic performance. The XF-91 had an afterburner, four rocket-engines, and was capable of Mach 1.71 with the rockets and everything running. It was most certainly supersonic.
3. The F102/106 did not originally incorporate the area rule and had difficulties at the sound barrier.
The YF-102 had no area-rule, the YF-102A was area-ruled as was the production F-102A; the F-106 was area-ruled from the get-go and was originally called the F-102B
4. Yes the area of the intakes count, as a function of the nose break. You have to factor in the nose section.
But if you don't have a nose-section, just an intake lip?
