Qinetiq Zephyr
The Qinetiq Zephyr is a series of lightweight solar-powered UAV originally designed and built by the United Kingdom company, QinetiQ.〔 〕 and is now part of the Airbus High Altitude Pseudo-Satellite (HAPS) programme. 〔(【引用サイトリンク】title=First flight of Astrium's Zephyr solar HAPS )〕
==Development==
The Zephyr 7 holds the official endurance record for an unmanned aerial vehicle for its flight from 9 July to 23 July 2010, lasting 336 hours and 22 minutes (2 weeks / 14 days).〔
Record claims have been verified by the Fédération Aéronautique Internationale (FAI) for both duration〔(【引用サイトリンク】title=FAI Record ID No. 16052 )〕 and altitude, at 21,562 meters. It more than doubled the previous endurance record for unmanned flight.
In a 2008 demonstration for the US military, a smaller-scale version of the Zephyr (Zephyr 6) performed beyond the official world record for the longest-duration unmanned flight, however its 82-hour flight at an altitude of 61,000 feet did not set an official record because FAI officials were not involved in the flight.
