2008-09-01 - Zephyr record flightQinetiQ's Zephyr UAV flies for three and a half days

Inoffizeller Weltrekord für UAV<br /> Zephyr's reputation as the world's leading solar powered high-altitude long-endurance (HALE) Unmanned Aerial Vehicle (UAV) has been reinforced with a world-beating three and a half day flight at the US Army's Yuma Proving Ground in Arizona. The solar powered plane flew for 82 hours 37 minutes, exceeding the current official world record for unmanned flight which stands at 30 hours 24 minutes set by Global Hawk in 2001 and Zephyr's previous longest flight of 54 hours achieved last year.

The UK Ministry of Defence has funded the development of Zephyr to date and has partnered with the US Department of Defense (DoD) under their Joint Capability Technology Demonstration (JCTD) Programme - which is designed to move urgently needed technologies rapidly into the hands of US forces in the field. The US DoD funded the demonstration flight under the Programme and this was the first time the two governments have participated in a joint demonstration of a HALE UAV. Launched by hand, Zephyr is an ultra-lightweight carbon-fibre aircraft. By day it flies on solar power generated by amorphous silicon solar arrays no thicker than sheets of paper that cover the aircraft's wings. By night it is powered by rechargeable lithium-sulphur batteries, supplied by SION Power Inc, which are recharged during the day using solar power.
The flight trial at Yuma took place between 28 and 31 July in the harsh conditions of the Sonoran Desert in mid summer with temperatures up to 45°C (113°F). Zephyr was flown on autopilot and via satellite communications to a maximum altitude of more than 60,000ft. The trial included a military utility assessment of a US Government communications payload.
