Solar spy plane sets unofficial 82 hour flight record
Tuesday, August 26th, 2008

The current world record for an unmanned flight stands at just over 30 hours and was set by the Northrop Grumman’s RQ-4 Global Hawk. But that record has unofficially been smashed by a new aircraft developed by QinetiQ.
The QinetiQ Zephyr Unmanned Aerial Vehicle (UAV) managed a flight time of 82 hours and 37 minutes soaring over the U.S. Army’s Yuma Proving Ground in Arizona. The flight was done to test a communications payload and did not meet the criteria to be classed as an official world record.
The Zephyr weighs just 30kg due to its carbon fibre frame, and is capable of carrying up to 2kg of cargo. To launch, it is held by 3 people and they run to gain speed before releasing the craft. When in flight it can be controlled via satellite communication or be set to run on autopilot.
The UAV is powered via solar energy and a rechargeable battery. The wings of the Zephyr have a layer of amorphous silicon solar arrays that provide the required energy and recharge the battery. The battery is present to allow the UAV to continue flight through the night.
Simon Bennett, managing director of QinetiQ’s Applied Technologies commented:
The Yuma Proving Ground in Arizona was an appropriate setting for Zephyr’s world beating flight as many landmark aviation developments have taken place there in recent years. In addition to setting a new unofficial record, the trial is a step towards the delivery of Zephyr’s capability for joint, real-time, battlefield persistent surveillance and communications to forces in the field at the earliest opportunity.

Matthew’s Opinion
The designers think this is just the start and those long hours will soon turn into months with a bit more development. That means we will have the capability of launching UAVs that could potentially provide commercial services as well as acting in a military capacity.
The technology should also be looked at by the aviation industry for commercial flights. Covering the wings and upper fuselage of commercial aircraft with the same solar arrays would surely produce a significant amount of energy to power on-board gadgets. The only question would be as to how resilient the arrays are to the elements and the constant take-off, fly, land, routine of these planes.
Early tests of the BlackBerry Bold reveal that the new handset is suffering from the same 3G connection problems as the iPhone 3G.
