What is Human-powered aircraft?
[[File:Daedalus Project's Light Eagle.jpg|thumb|right|200px|A human powered aircraft]] A '''human powered [[aircraft]]''' is an aircraft that is powered entirely or partly by the [[pilot]](s). Several human powered aircraft have been [[construct]]ed in the past 30 years for [[recreation]] or to win [[prize]]s. Designing a successful human-powered aircraft is difficult because a very large [[power to weight ratio]] must be [[wikt:achieve|achieve]]d. This has been the reason why many of these aircraft use [[wikt:advanced|advanced]] [[composite]] [[material]]s in their [[construction]]. There are human-powered aircraft being [[design]]ed and made now. One aircraft is being built by [[Virginia Tech University]] named the Iron Butterfly. Another one is being built by the [[Pennsylvania State University]] named the [[Zephyrus]]. ==References== {{Reflist|2}} * [http://www.humanpoweredflying.propdesigner.co.uk/index.html History of man-powered flight] {{Webarchive|url=https://web.archive.org/web/20160313235455/http://www.humanpoweredflying.propdesigner.co.uk/index.html |date=2016-03-13 }} * [http://www.teamicarus.com/wa.asp?idWebPage=15322&idDetails=114 Chronology and pictures] * [http://BlueFalkor.tudelft.nl Blue Falkor Human Powered Aircraft project at TU Delft The Netherlands] {{Webarchive|url=https://web.archive.org/web/20071112204317/http://bluefalkor.tudelft.nl/ |date=2007-11-12 }} {{aircraft}} [[Category:Aircraft]]
