Flapping-wing airplanes are envisioned.
ANN ARBOR, Mich., Feb. 5 (UPI) -- U.S. scientists are studying birds, bats and insects and their aerobatic efficiencies as a step toward designing flapping-wing airplanes.
University of Michigan engineers said such planes of the future might have wingspans smaller than a deck of playing cards and the aerodynamics of flying animals that can outperform current man-made aircraft.
For example, the engineers note 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.
"Natural flyers obviously have ...
