Researchers
at the Massachusetts Institute
of Technology rolled a model X-Cell 60 helicopter 180[degrees],
flew it upside down for a second, then completed a half loop
to end up flying upright in the opposite direction, all by flipping
a switch on a remote control. The maneuver, called split-S,
lets an aircraft reverse direction quickly in a horizontally
confined space. It's one of a variety of aggressive, agile maneuvers
that the next generation of unmanned aerial vehicles (UAVs)
will be expected to perform in military combat.
The technology developed by MIT
researchers makes it possible for anyone to operate the aerobatic
craft. Small, agile, autonomous helicopters like MIT's X-Cell
60 may provide a new tool for military reconnaissance or weapons
delivery in mountainous or other challenging terrain that is off
limits to larger aircraft and too dangerous for manned aircraft.
Their small size, ease of operation, and potentially low cost
compared with the current generation of UAVs, such as the Predator,
make this option appealing not only to the military, but to the
entertainment industry as well.
