If
you want to get an advanced look at the future of aircraft design... you may
want to head for the beach, and watch as seagulls glide over the waves.
National
Geographic magazine reports scientists have found airplane wings shaped
similarly to those of some seagulls may reduce drag during flight, thus saving
fuel. In fact, a wing modeled after a seagull registered a 4-percent
improvement in drag over the theoretical "best" conventional aircraft
wing.
So
what's different about a seagull-shaped wing? Well, the seagull-wing is highly
cambered along its span -- with a prominent bend along the surface, before
turning down at the tip.
It's
that down turned edge that most interests scientists, says Ken Visser, a NY
scientist who is conducting research at Germany's Institute of Aerodynamics and
Flow Technology. The design reduces the swirling vortex that disturbs airflow
on conventional wings, and keeps the vortex from moving inboard toward the body
of the plane.
Despite
the promising research, however... it's unlikely we'll see any seagull-inspired
planes any time soon over here, as NASA continues to focus its efforts more
towards the "space" part of its name, and less and less money is
devoted to "aeronautics."
There
are also questions of weight, and maneuverability... although the latter seems
to hold promise, as well. After all... have you ever seen a seagull dive for
food? Nothing moves faster...
