These model kits, designed by Nathan Chronister, are your best choice
for getting started in building your own ornithopters.
National Robotics Education Foundation
The NREF helps educators to prepare students for careers in science,
technology, engineering, and math by identifying the most accessible
and affordable curricula, products, and learning resources.
Ptera software, developed by Cameron Urban, is a fast, easy-to-use,
and open-source package for analyzing flapping-wing flight.
Series Ornithopters by Horst Räbiger
The EV series ornithopters were a significant contribution to the
development of flapping-wing flight, the first to combine mechanically
driven twisting of the wings with a thick airfoil instead of membrane
wing. Räbiger also includes some great historical information
and technical data about aspects of ornithopter design.
University of Delft
This research program in the Netherlands has produced the Delfly,
which is a small, hoverable radio-controlled ornithopter that can
carry a camera. It is being applied for military use.
Albert Kempf's flying toucan introduced a flexible foam wing
with actively driven wing twist. His web site describes the ornithopter
and also has a great section on how birds fly.
Flight Web Site
This is a separate web site that I created, which focuses on
flapping-wing flight in nature, instead of ornithopters. It has
information about birds, bats, pterosaurs, insects, and flying fish.
Learn how to attract hummingbirds to your yard, and make a fun family
activity out of it.
