GRUMMAN X-29A
The X-29 was built to explore state-of-the-art technologies in
aircraft design. The most easily identified of these, the forward-
swept wing (FSW) was combined with advanced materials, a forward
mounted elevator (canard) and an electrical flight control system.
The purpose of this combination of features was to test how well
all these elements worked together before they were used in future
aircraft.
Both Germany and the U.S. experimented with FSW aircraft during
World War II but did not use them operationally. One problem with
the new design was that the wings could not be made rigid enough to
keep them from bending dangerously at higher speeds. In the 1970s,
however, composite materials became available, and wing structures
could be built that were both lightweight and very rigid.
Grumman began building the first of two X-29As in 1982. The pro-
gram was administered by the U.S. Air Force and jointly funded by
the Defense Advanced Research Projects Agency (DARPA), the Air Force,
and the National Aeronautics and Space Administration (NASA).
The first X-29A (S/N 82-003) made its initial flight on December
14, 1984 at Edwards AFB, California. On December 13, 1985, during
its 26th flight, this aircraft became the world's first FSW aircraft
to exceed the speed of sound in level flight. After successfully
completing the test program, the X-29A was retired to the Museum in
late 1994. The second X-29A made its first flight on May 23, 1989
and continued to perform test flights well into the 1990s.
