Ornithopter Web Sites

These model kits, designed by Nathan Chronister, are your best choice for getting started in building your own ornithopters.

The 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
Ptera software, developed by Cameron Urban, is a fast, easy-to-use, and open-source package for analyzing flapping-wing flight.

EV 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.

Technical 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.

Bird 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.

Attract Hummingbirds
Learn how to attract hummingbirds to your yard, and make a fun family activity out of it.

Ornithology Resources
A collection of interesting web sites about birds.
