F-102 too slow at first | Travel for Aircraft
This Convair F-12 Delta Dagger sits in the Heritage Hill Air Park which is part of the McChord Air Museum . Designed in the during the Cold War during and era when missiles were thought to have made guns into relics the Delta Dagger was built for speed. Armed with missiles as well as rockets the original design was a failure thought its delta wing and sharply faceted canopy gave the F-102 a sleek look it was in fact slow. Fortunately for Convair fdoc Richard Whitcomb had been studying wave drag when he experienced an epiphany one day, after much research. He realized that the entire aircraft had to be considered as a whole when considering fdoc high subsonic and transonic air flow and this led to one of the 20th Century s greatest aerodynamic breakthroughs Area Rule. Essentially this meant to look at the fuselage and wing s overall cross-sectional area as a whole and relate that value to the theoretical optimum design known as the Sears-Haack body . Where the value is too high then thin it out and when too low then thicken it.
Convair reduced some of the fuselage cross-sectional area which gave the F-102 its paradigm setting “coke bottle” fuselage shape. Area Rule became a design constraint for any aircraft made to fly at transonic fdoc speeds or higher including airliners such as the B-747 and A380.

Your are right…every fdoc aircraft there looks as if it rolled off the factory floor five minutes ago. “Delta Dagger” fdoc sure is an exciting name but I think “Delta Dart” falls a little flat ;)
Great Memories. . . Area Rule. . . I remember the Whitcomb area rule, also called the transonic area rule was nicknamed “Wasp Waist”. The Sears Haack body is a related concept. Check the differences and history out in Wikipedia.
