The Dragonfly was invented by Sean Frawley and Dan Getz who began experimenting with ornithopters while they were still teenagers. [1] The four-winged design of the Dragonfly was based on a previous rubber-band-powered ornithopter kit designed by Nathan Chronister and manufactured by The Ornithopter Zone.
Other ornithopters do not necessarily act like birds or bats in flight. Typically birds and bats have thin and cambered wings to produce lift and thrust. Ornithopters with thinner wings have a limited angle of attack but provide optimum minimum-drag performance for a single lift coefficient. [39]
SmartBird is an autonomous ornithopter created by Festo's Bionic Learning Network with an emphasis on better aerodynamics and maneuverability. It is an ornithopter modeled on the herring gull. [1] It has a mass of 450 grams and a wingspan of 1.96 meters. [2] In April 2011 the SmartBird was unveiled at the Hanover Fair.
The terrestrial Entomopter is a multimode (flying/crawling) insect-like robot developed by Robert C. Michelson and his design team from the Georgia Tech Research Institute (GTRI), University of Cambridge, ETS Labs and others.
The DelFly project started in 2005 as a Design Synthesis Exercise for a group of Bachelor of Science students at the Faculty of Aerospace Engineering of the TU Delft.The flapping wing design was mentored by Wageningen University, [3] the remote control and micro camera integration by Ruijsink Dynamic Engineering, and the real-time image processing by the TU Delft.

[1] [4] Take-off was assisted with a tow from a car to get the aircraft up to speed, before flapping for lift-off. [1] A total of 16 flaps were used on the run to maintain height. [ 1 ] At the start of the flight, data indicates that the Snowbird was able to gain height, while maintaining speed, indicating that there was more power than ...

The ornithopter was a high-wing monoplane, with the pilot seated in a recumbent position. Its construction followed conventional glider practice of the time. The fuselage had a bulkhead construction, covered in thin plywood .
