Birds Give a Lesson to Plane Designers 250
Roland Piquepaille points out a news release from the University of Michigan where researchers are looking to birds and bats for insights into aerospace engineering. Wei Shyy and his colleagues are learning from solutions developed by nature and applying them to the technology of flight. A presentation on this topic was also given at the 2005 TED conference. From the news release:
"The roll rate of the aerobatic A-4 Skyhawk plane is about 720 degrees per second. The roll rate of a barn swallow exceeds 5,000 degrees per second. Select military aircraft can withstand gravitational forces of 8-10 G. Many birds routinely experience positive G-forces greater than 10 G and up to 14 G. Flapping flight is inherently unsteady, but that's why it works so well. Birds, bats and insects fly in a messy environment full of gusts traveling at speeds similar to their own. Yet they can react almost instantaneously and adapt with their flexible wings."

A Skyhawk, on the other hand, could carry a large number of coconuts. However, unlike with the swallows (where the main issue is not the grip but the weight ratios), the Skyhawk would be limited by the number of coconuts that could be attached. The Skyhawk is an attack aircraft with a payload of close to 10,000 lbs, which would make for a lot of coconuts. But, the only reasonable place to attach large numbers of them without causing aerodynamic interference would be the wing pylons, where the bombs usually go. If they were to fit, these coconut packages could not be much bigger than the bombs. As there are only five hardpoints, I can't imagine there being room for more than about 50 coconuts.
Still, this is a significant improvement over the swallows, and if you had to choose between the two, the Skyhawk would be a much better choice for migrating coconuts into temperate climes. Of course, something like a C-17 would be even better, but those have an even lower roll rate.
