QinetiQ Zephyr

QinetiQ Zephyr

Zephyr is a lightweight solar-powered plane engineered by the United Kingdom defence firm, QinetiQ. It is of carbon-fibre construction, and uses sunlight to charge lithium-sulphur batteries during the day, which power the aircraft at night. The aircraft has been designed for use in observation and communications relay.cite news

The Zephyr holds the world record for the longest duration unmanned flight with a 54-hour, 58,355 foot flight in September 2007.

In a demonstration for the US military, the Zephyr performed beyond the official world record for the longest-duration unmanned flight, however its 82-hour flight did not set an official record due to the fact that the Federation Aeronautique Internationale was not involved in the flight.cite news
