Flying Wings
The Northrop B-2 is a flying wing bomber that has corporate,
structural and sentimental connections to the famous XB-35 and
YB-49 aircraft of the 1940s. The present Northrop Corporation
has always denied that there was any direct engineering
relationship between the aircraft. But their obvious
similarities in shape, concept and wingspan have fixed in the
public mind that the modern B-2 is a direct descendant of John
Northrop's most famous designs.
John K. Northrop's goal was to create a plane shaped like a
flying wing. This innovative aviation designer believed the
flying wing was the ideal shape for an aircraft. He based his
theory on the concept that the fuselage of a conventional
aircraft develops little lift and much drag, while the empennage
not only creates drag but has horizontal surfaces that are often
designed to provide negative lift. If you wanted to eliminate
drag, you were left with only the wing.
In the 1940s, Northrop developed a series of "flying wings" that
culminated in the YB-49 series. Although these planes were
advanced aerodynamically, they had problems with stability and
were not stable bombing platforms. Another problem was that the
YB-49, while jet powered, was saddled with an airframe built with
technology designed for piston-powered planes. In 1949, the U.S.
government cancelled the Northrop flying-wing program for
technical and political reasons.
