Recently resumed flight testing and payload evaluations in Yuma, Arizona when a joint US/UK team undertook the first operation
QinetiQ’s Zephyr High-Altitude Long-Endurance unmanned aerial system (HALE UAS) programme recently resumed flight testing and payload evaluations in Yuma, Arizona, when a joint US/UK Zephyr team undertook the first operation of the system with a US flight crew.
This test sequence, jointly sponsored by MOD UK and OSD DDRE JCTD programme, focused on evaluating potential payloads as well as advancing the conops for operating long endurance persistent aircraft in excess of five days.
The Zephyr concept is designed to offer solar-powered, persistent coverage with continuous mission durations of up to three months at a revolutionary low-cost per flight hour. Capable of carrying a variety of payloads, the applications of the system include wide area surveillance, communications relay, specific target monitoring, anti-piracy efforts, route monitoring, counter-IED, border security, and local area security.
An ultra-lightweight carbon-fibre aircraft, Zephyr weighing less than 100 pounds with a wingspan of up to 75 feet. Launched by hand, Zephyr is solar powered during the day using United Solar Ovonic amorphous silicon arrays no thicker than sheets of paper that cover the aircraft’s wings. At night it is powered by lithium-sulphur batteries supplied by the SION Power Corporation that are recharged during the day using solar power.
The US Army’s Yuma proving ground in Arizona was the siite of Zephyr’s world-beating three and a half day flight in July’08 – the fourth of a series of flight trials that have been flown in the US since 2005.
