Zephyr, the solar-powered, high altitude long endurance (HALE) unmanned vehicle developed by QinetiQ has been flying for the past week, smashing a number of long-standing world records.

The solar powered drone mission continues above the US Army’s Yuma Proving Ground in Arizona, as part demonstrating the solar powered drone’s capability to fly a two week mission. “By being able to remain over a location for weeks or months at a time, it can usefully deliver a host of practical and more affordable solutions to both civil and military customers” said Jon Saltmarsh, Zephyr Program Director at QinetiQ.

A Larger Zephyr

The current goal is to fly for a further week and prove Zephyr is the world’s first truly eternal plane, capable of providing a low-cost, persistent surveillance capability over months rather than days. Potential applications include earth observation and communications relay in support of a range of defense, security and commercial requirements.

Unlike conventional manned or unmanned aircraft now being operated, Zephyr does not need to return to base at regular intervals for re-fuelling or servicing which also helps minimize the logistical supply chain and extend its operational capability.

Around 50% larger than the previous Zephyr, technical changes now mean it has a 22.5m wingspan to accommodate more batteries that are combined with a totally new integrated power management system. The entirely new aerodynamic shape and high “T” tail also contribute to reduce drag and improve performance. The payload capacity will meet a number of key surveillance and communication requirements already demonstrated by Zephyr over the past three years. Zephyr’s ultra-lightweight carbon-fibre design also means it weighs in at just over 50Kg.

“The current Zephyr aircraft is a genuine breakthrough design, drawing on the latest technology and represents a massive leap forward in engineering excellence incorporating an entirely new wing design.” Saltmarsh explained. Launched by hand, the aircraft flies by day on solar power delivered by amorphous silicon solar arrays no thicker than sheets of paper that cover the aircraft’s wings. These are also used to recharge the lithium-sulphur batteries, supplied by Sion Power Inc, which are used to power the aircraft by night. Together they provide an extremely high power to weight ratio on a continuous day/night cycle, thereby delivering persistent on-station capabilities.

Claiming the World Endurance Record for UAVs

On July 23, 2010 Zephyr successfully landed after 14 days (336 hours) and 21 minutes flying over Arizona.  and is now awaiting official confirmation of its world record status. Following the flight, QinetiQ is claiming three world records for the Zephyr:

• the absolute duration record for an Unmanned Air Vehicle – being filed at 336 hrs / 22 minutes
• the duration record for a UAV (in the U/1.c / 50-500Kg category) – time as above
• the absolute altitude record for a UAV (in the above category) – being filed at 70,740ft (21,561m)

This record far exceeds the unofficial world record for longest duration unmanned flight of 82 hours, 37 minutes set in 2008 and already held by Zephyr, and is well in excess of the current official world record of 30 hours 24 minutes set by Northrop Grumman’s RQ-4A Global Hawk on 22 March 2001. Upon landing, plans to claim the world record for HALE UAV flight endurance. The company invited the Federation Aeronautique Internationale (FAI), the world air sports federation, to oversee the flight and an FAI Official has been monitoring progress at the Yuma Proving Ground.

QinetiQ was awarded $45 million by the U.S. Navy for the delivery of seven Zephyrs, QinetiQ will produce the Zephyrs at Farnborough, in the United Kingdom. The seven aircraft are expected to be delivered win 2014.

07/23/2010 Update: QinetiQ to land its Zephyr solar powered aircraft

QinetiQ will today bring Zephyr, its solar powered high-altitude long endurance (HALE) Unmanned Air System (UAS) back to earth after two weeks in the air, smashing a number of long-standing official and unofficial world records.

Zephyr was launched on 09 July and is currently still flying above the US Army’s Yuma Proving Ground in Arizona. Today Zephyr will have been aloft for 14 nights continuously, achieving the objective of the trial and setting a number of performance and altitude records. At this point QinetiQ’s Zephyr team in Yuma will bring the aircraft back to earth.

With the Phantom Eye's 150 foot wing span and two hydrogen-propelled engines, Phantom Eye will be able to carry a 450 lp payload on missions spanning over several days, at an altitude of 65,000 ft. Photo: Boeing

The Boeing Company [NYSE: BA] today unveiled the hydrogen-powered Phantom Eye unmanned airborne system, a demonstrator that will stay aloft at 65,000 feet for up to four days. Later this summer, Phantom Eye will be shipped to NASA’s Dryden Flight Research Center at Edwards Air Force Base, Calif., to begin a series of ground and taxi tests in preparation for its first flight in early 2011. That debut flight is expected to last between four and eight hours.

With a 150-foot wingspan, Phantom Eye will cruise at approximately 150 knots and can carry up to a 450-pound payload. It is powered by two 2.3-liter, four-cylinder hydrogen fuelled engines that provide 150 horsepower each. “The hydrogen propulsion system will be the key to Phantom Eye’s success” said Darryl Davis, president of Boeing Phantom Works, “It is very efficient and offers great fuel economy, and its only byproduct is water, so it’s also a ‘green’ aircraft.”

“Phantom Eye is the first of its kind and could open up a whole new market in collecting data and communications,” said today at the unveiling ceremony in St. Louis. Key Phantom Eye suppliers and partners include Ford Motor Company (engines), Aurora Flight Sciences (wing), Mahle Powertrain (propulsion controls), Ball Aerospace (fuel tanks), Turbosolutions Engineering (turbochargers), the Defense Advanced Research Projects Agency and NASA.

The Euro Hawk unmanned aircraft system (UAS), built by Northrop Grumman Corporation and EADS Defence & Security, successfully completed its first flight June 29. The high-flying aircraft took off at approximately 10:32 a.m. PDT from Northrop Grumman’s Palmdale, Calif., manufacturing facility and climbed to 32,000 feet over Palmdale’s desert skies before landing nearly two hours later at 12:24 p.m. PDT at Edwards Air Force Base, Calif.

The German Ministry of Defense awarded a contract in January 2007 to EuroHawk GmbH a 50-50 joint venture company by Northrop Grumman and EADS Defence & Security, for the development, test and support of the Euro Hawk SIGINT surveillance and reconnaissance system.

Based on the Block 20 Global Hawk, Euro Hawk will be equipped with new signals intelligence (SIGINT) mission system developed by EADS, providing standoff capability to detect electronic and communications emitters. A ground station consisting of a mission control and launch and recovery elements will be provided by Northrop Grumman. EADS Defence & Security will also provide a SIGINT ground station, which will receive and analyze the data from Euro Hawk as part of an integrated system solution.

The Euro Hawk has a mission endurance of 30 hours and a maximum altitude of more than 60,000 feet. It is an interoperable, modular and cost-effective replacement to the aging fleet of manned Breguet Atlantic aircraft, which have been in service since 1972 and will be retired in 2010. Subsequent systems are anticipated for delivery between 2016 and 2017 following successful testing and introduction in German operational service.

Northrop Grumman is planning to conduct an aerial refueling demonstration performed by two Global Hawk HALE UAVs, under a DARPA funding. Illustration: Northrop Grumman

Northrop Grumman, National Air and Space Agency (NASA) and the Defense Advanced Research Projects Agency (DARPA) are planning to demonstrate aerial refueling of a NASA Global Hawk autonomous aerial vehicles by a sister ship.  The program will be designated KQ-X.

The agency allocated US$33 million for Northrop Grumman, to conduct the autonomous refueling demonstration within the next two years. The demonstration perform the first-ever fully autonomous rendezvous, rejoin, station keeping, aerial refueling, and formation separation of two unmanned aircraft.  The flight will be conducted at altitudes typically flown by the Global Hawk’, hence, overcoming inherent limitations of high altitude flight in thin atmosphere and limited control authority associated with long-endurance aircraft. “The importance of aerial refueling is clear in the way military aviation depends on it today,” said Jim McCormick, the DARPA program manager for KQ-X. ”This demonstration will go a long way towards making those same advantages a reality for the next generation of unmanned aircraft.” A successful outcome will allow developers of future unmanned aircraft to produce more cost-effective systems that rely on aerial refueling for the most demanding missions.

Northrop Grumman will retrofit two of the high altitude long endurance (HALE) UAVs, one aircraft pumping fuel into the other in flight through a hose-and-drogue refueling system. The aerial refueling engagement will be completely autonomous. Engineering work will be accomplished at the Northrop Grumman Unmanned Systems Development Center in Rancho Bernardo, California. Pilots from NASA, NOAA, and Northrop Grumman will fly the Global Hawks from the NASA Dryden Flight Research Center at Edwards Air Force Base, also in California. Sargent Fletcher, Inc. and Sierra Nevada Corporation are major KQ-X subcontractors.
