Site of the Day for Wednesday, June 9, 2004 Project Ornithopter Today's site, from the University of Toronto's Institute for Aerospace Studies, offers a look at that aviation oddity -- the ornithopter. Gentle Subscribers who are somewhat bemused by the notion of mechanical flapping wings will discover a serious academic study devoted to this now unusual approach to aircraft design. "This website will describe ornithopter research, design, and testing. .... Included will be the project's history as well as current results. ... The purpose of this project is to achieve humanity's oldest aeronautical dream: flight with mechanical flapping wings. Many early aircraft concepts assumed that such imitation of birds and bats was the proper design direction. However, the challenge of achieving both efficient lift and thrust with flapping wings was far greater than simply using the wings for lift and providing thrust with a separate propulsor. " - from the website The site provides a history of the ornithopter, how it works and a multimedia presentation of photos and videos of the aircraft, including a flight simulator. One of the project's pilots offers a brief but enthusiastic commentary while a technical paper on wing design is available in .pdf format.
