A most interesting paper on flight motions to explain
how bumblebees and other ungainly insects
fly....motions ya say??;
http://unisci.com/stories/19992/0618994.htm
Using a pair of robotic wings they've dubbed
"robofly," Michael Dickinson and his colleagues at UC
Berkeley have found three distinct wing motions that
not only allow insects like flies and bees to stay
airborne, but also let them steer and execute amazing
acrobatic maneuvers. These mechanisms seem to be
common to most insects, and perhaps even to the
hummingbird.
"Engineers say they can prove that a bumblebee can't
fly," said Dickinson, an assistant professor of
integrative biology. "And if you apply the theory of
fixed wing aircraft to insects, you do calculate they
can't fly. You have to use something different.
"We now have a unified theory of insect flight
aerodynamics that explains how they can steer and
maneuver. We've solved the old riddle."
