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.

The 30th MC-12 Liberty was recently deployed to the U.S. Central Command area of responsibility completing the initial deployment plan, an Air Force official announced July 9. MC-12 Liberty ISR aircraft are currently operating with three units in SOuthwest Asia: the 361st Expeditionary Reconnaissance Squadron operating from Kandahar, Afghanistan and the 4th Expeditionary Reconnaissance Squadron stationed in Bagram, Afghanistan and the 362nd Expeditionary Reconnaissance Squadron in Balad air base, Iraq.

According to Lt. Gen. David A. Deptula, the deputy chief of staff for Intelligence, Surveillance and Reconnaissance at Headquarters Air Force, the aircraft has had a positive impact in theater. He added that the MC-12s assisted in the capture of hundreds of insurgents, and the discovery of weapons caches and improvised explosive devices. The MC-12 fleet has flown more than 5,000 combat sorties and taken more than 22,000 hours of full-motion video and more than 40,000 images to date. ”This project is an unqualified success, and the model for how we should develop and deliver quick-reaction ISR capabilities,” General Deptula said.

“The MC-12W is the fastest weapons system delivered from concept to combat since the P-51 Mustang in World War II” said “We mobilized a significant industry base and every resource at our disposal, and delivered the first Federal Aviation Administration-certified aircraft in six months and three weeks, It began flying combat sorties in less than eight months.”

In April 2008, Secretary of Defense Robert M. Gates established a Department of Defense-wide ISR Task Force to identify and recommend solutions for increased ISR in the CENTCOM AOR. Secretary Gates tasked Air Force officials July 1, 2008, to acquire 37 “C-12″ class aircraft to augment unmanned systems. It was less than eight months from funding approval to the delivery of the first aircraft in theater. The entire operational fleet of 30 aircraft was deployed in only 13 months.

“The entire Project Liberty team worked seamlessly to get this airborne ISR capability to the AOR as quickly as possible,” said Lt. Gen Craig Koziol, the DOD ISR Task Force director. “From concept to all the sensor integration efforts required to get this platform deployed, the team demonstrated superb focus to get this quick reaction, airborne ISR capability fielded to support (Operation Enduring Freedom and Operation Iraqi Freedom).”

The aircraft are military versions of the Hawker Beechcraft Super King Air 350 and Super King 350ER. They are equipped with an electro-optical infrared sensor, and other sensors as the mission requires. The EO/IR sensor also includes a laser illuminator and designator in a single sensor package. A fully operational system consists of a modified aircraft with sensors, a ground exploitation cell, line-of-sight and satellite communications data-links, and a robust voice communications suite. The MC-12 capability supports all aspects of the Air Force Irregular Warfare mission — counter insurgency, foreign internal defense and building partnership capacity — and is capable of worldwide operations.

With the Air Force MC-12 program winding down, the U.S. Army is gearing up to replace its Guardrail aircraft with C-12 based platforms, equipped to carry out a wider range of missions, beyond the traditional electronic surveillance performed by the Guardrail.
