The power of jet engines with afterburners created these speeds technically doable, but designers were being even now handicapped by the large increase in drag from the transonic space. The answer involved incorporating quantity to the fuselage ahead of and guiding the wing and decreasing it near the wing and tail, to create a cross-sectional place that a lot more practically approximated the ideal region to Restrict transonic drag. Early programs of this rule resulted in a very “wasp-waistline” look, such as that on the Convair F-102. In later jets software of this rule will not be as apparent inside the aircraft’s planform.
