American XB-70 Valkyrie
The XB-70, one of the world's most
exotic airplanes, was conceived for the Strategic Air Command in
the 1950s as a high-altitude bomber that could fly three times
the speed of sound (Mach 3). Because of fund limitations, only
two were built, not as bombers, but as research aircraft for the
advanced study of aerodynamics, propulsion, and other subjects
related to large supersonic aircraft. The Valkyrie was built
largely of stainless-steel honeycomb sandwich panels and
titanium. It was designed to make use of a phenomenon called
"compression lift," achieved when the shock wave
generated by the airplane flying at supersonic speeds supports
part of the airplane's weight. For improved stability at
supersonic speeds, the Valkyrie could droop its wingtips as much
as 65 degrees.
