Shrike VTOL represents the conclusion of this development effort.

"With more than four years of customer funding behind it, our new Shrike VTOL unmanned aircraft system is designed to address the need for a small, light-weight hovering aircraft that delivers unique surveillance and intelligence capability not provided by current solutions.

"Not only does Shrike VTOL hover for more than 40 minutes with a high resolution video camera, but its innovative design also allows for the transmission of several hours of live video as a remotely emplaced perch and stare sensor," said Tom Herring, senior vice president and general manager of AeroVironment's UAS business segment.

"This new solution adds an important set of new capabilities to our existing and battle-proven family of small unmanned aircraft systems that are saving lives in theater today."

Herring said the Shrike VTOL system delivers the superior imagery, endurance and encrypted video found in all AeroVironment small unmanned aircraft systems. Operating quietly enough to go virtually undetected, Shrike weighs approximately five pounds and is small enough to fit in a backpack.

AeroVironment's Family of Small UAS
Raven, Wasp and Puma comprise AeroVironment's Family of Small Unmanned Aircraft Systems. Operating with a common ground control system (GCS), this Family of Systems provides increased capability to the warfighter that can give ground commanders the option of selecting the appropriate aircraft based on the type of mission to be performed.

This increased capability has the potential to provide significant force protection and force multiplication benefits to small tactical units.

AeroVironment's UAS logistics operation supports systems deployed worldwide to ensure a consistently high level of operational readiness. AeroVironment has delivered thousands of new and replacement small unmanned air vehicles. International purchasers of AeroVironment's small UAS include the armed forces of Italy, Denmark, the Netherlands, Spain, France, Norway, the Czech Republic, Thailand and Australia.

The milestone was part of the Phase II contract awarded by the Defense Advanced Research Projects Agency (DARPA) to AV to design and build a flying prototype "hummingbird-like" aircraft for the Nano Air Vehicle (NAV) program.

"The success of the NAV program paves the way for a new generation of aircraft with the agility and appearance of small birds," said DARPA NAV program manager, Dr. Todd Hylton.

The final concept demonstrator is called the 'Nano Hummingbird' and is capable of climbing and descending vertically, flying sideways left and right, flying forward and backward, as well as rotating clockwise and counter-clockwise, under remote control and carrying a video camera payload. During the demonstration the Nano Hummingbird flew in and out of a building through a normal-size doorway.

"The historic achievement made by the Nano Hummingbird is an example of the leading-edge innovations introduced and deployed almost routinely by the AeroVironment UAS team," said Tom Herring, AV senior vice president and general manager of Unmanned Aircraft Systems.

"From the battle-proven Raven, Wasp and Puma small UAS to the tiny Nano Hummingbird to Global Observer, the largest, highest and longest flying UAS, AeroVironment continues to define the future of unmanned aircraft systems. Our mission in doing so is to provide our customers with advanced tools that help them succeed."

The hand-made prototype aircraft has a wingspan of 16 centimeters (6.5 inches) tip-to-tip and has a total flying weight of 19 grams (2/3 ounce), which is less than the weight of a common AA battery. This includes all the systems required for flight; batteries, motors, communications systems and video camera.

The aircraft can be fitted with a removable body fairing, which is shaped to have the appearance of a real hummingbird. The aircraft is larger and heavier than an average hummingbird, but is smaller and lighter than the largest hummingbird currently found in nature.

"The success of the Nano Hummingbird was highly dependent on the intense combination of creative, scientific, and artistic problem-solving skills from the many AV team members, aided by a philosophy of continuous learning, which we feel was only possible due to the unique R and D environment here at AV," said Matt Keennon, AV's project manager and principal investigator on the NAV project.

The technical goals for the Phase II effort were set out by DARPA as flight test milestones for the aircraft to achieve by the end of the contract effort.

The Nano Hummingbird met all, and exceeded many, of the milestones:

• Demonstrate precision hover flight within a virtual two-meter diameter sphere for one minute;
• Demonstrate hover stability in a wind gust flight which required the aircraft to hover and tolerate a two-meter per second (five miles per hour) wind gust from the side, without drifting downwind more than one meter;
• Demonstrate a continuous hover endurance of eight minutes with no external power source;
• Fly and demonstrate controlled, transition flight from hover to 11 miles per hour fast forward flight and back to hover flight;
• Demonstrate flying from outdoors to indoors, and back outdoors through a normal-size doorway;
• Demonstrate flying indoors 'heads-down' where the pilot operates the aircraft only looking at the live video image stream from the aircraft, without looking at or hearing the aircraft directly;
• Fly the aircraft in hover and fast forward flight with bird-shaped body and bird-shaped wings.

This milestone marks the beginning of high altitude, long endurance flight testing for the demonstration and operational utility phase of the Joint Capability Technology Demonstration (JCTD) program.

“Global Observer has moved quickly from development and testing toward demonstrating mission-ready, affordable persistence,” said Tim Conver, AV chairman and chief executive officer. “Similar to a satellite, Global Observer is the first system designed to provide a 24/7/365 unblinking eye and continuous communications link over any location on the earth’s surface for as long as needed. The joint AV and U.S. government team developed Global Observer to meet today’s urgent requirements for persistence and to enable the development of much more cost-effective solutions for the future. The speed with which we have achieved this milestone reflects the benefits of an effective government-industry partnership.”

Because of its extreme endurance and range, Global Observer can be based out-of-theater, which will further reduce operating costs and local air traffic congestion while significantly reducing risk to operational personnel. AV plans to make Global Observer systems available for procurement and for operation as a turnkey service to provide communications and remote imaging in a manner similar to satellite services, but at a much lower cost.

The hydrogen-powered flight lasted for four hours and reached an altitude of 5,000 feet above sea level over the United States Air Force Flight Test Center at EAFB. This first flight follows the successful battery-powered flight test phase of the demonstration program that took place during the months of August and September.

The flight test team will now systematically expand the altitude and duration of test flights to validate the aircraft’s high-altitude, long endurance performance. These flights will include the Air Force's Joint Aerial Layer Network (JALN) Tactical Communications Suite (TCS) payload. The JALN TCS provides persistent, IP-based aerial communications infrastructure that extends communications from a Global Observer aircraft positioned at 65,000 feet above sea level over a wide area. The joint operational utility of the Global Observer system will also be assessed during this flight test series for future U.S. Government, civil, and military uses.

With 20 years of experience developing stratospheric, long-endurance unmanned aircraft systems (UAS), AV is developing Global Observer to operate as a “stratospheric geosynchronous satellite system” with regional coverage and minimal signal delay. Two Global Observer aircraft, each flying for up to a week at a time, will alternate coverage over any area on the earth, providing a seamless, persistent platform for high value missions such as communications relay, remote sensing, long-term surveillance and border patrol. Offering greater flexibility than a satellite and significantly longer duration than conventional manned and unmanned aircraft, Global Observer is designed to provide critical new capabilities in a reliable and more affordable manner, all while consuming no fossil fuels and emitting no carbon emissions.

In addition to flying above weather and above other conventional airplanes, operation at 55,000 to 65,000 altitude enables sensor payloads on the aircraft to view a significantly larger area on the surface of the earth than conventional, lower flying aircraft. Equipped with payloads that are readily available today, a two Global Observer system would provide persistent satellite-like coverage over any location on the globe at a fraction of the cost of satellites.

AV received the contract for developing and demonstrating Global Observer as a JCTD program in September 2007. Six U.S. government agencies have provided more than $140 million in funding for the program.

AV is a technology solutions provider that designs, develops, produces and supports an advanced portfolio of Unmanned Aircraft Systems (UAS) and electric transportation solutions.

Switchblade is a small UAS designed to provide a rapid, lethal, pinpoint precision strike capability with minimal collateral damage. AV’s electric transportation solutions include a comprehensive suite of electric vehicle (EV) charging systems and installation services for consumers, automakers, utilities and government agencies, power cycling and test systems for EV developers and industrial electric vehicle charging systems for commercial fleets.

This initial flight test phase of the demonstration program employed batteries to power the hybrid-electric aircraft and to approximate full aircraft weight and center of gravity for flight control, performance and responsiveness evaluation.

The program team has installed and is currently ground testing the aircraft’s innovative, hydrogen-fueled generator and liquid hydrogen fuel tanks which will power it through stratospheric, extreme endurance flights during the joint operational utility assessment phase of the program.

“These successful flights validated Global Observer’s airworthiness, and represent critical milestones as the team proceeds toward demonstrating stratospheric, extreme endurance operations,” said Tim Conver, AV’s president and chief executive officer. “The liquid-hydrogen fueled flight test series will be historic for AV and the JCTD team as Global Observer moves closer to demonstrating mission-readiness and supporting our troops whenever and wherever needed.”

The initial test flights took place during the months of August and September and have succeeded in achieving the primary objectives of the low altitude flight test program. The primary objectives for initial flight testing were to test guidance, manual and autonomous controls, navigation, structural performance, thrust levels and handling in various winds and turbulence conditions.

AV also has successfully operated Global Observer’s hydrogen-fueled generator for more than 1,500 hours in a specialized environmental chamber, including an uninterrupted 7-day mission cycle. The chamber subjects the generator to the range of temperatures, pressures and air densities that the aircraft will experience during the climb, loiter and descent stages of high altitude missions. Successful wing load tests performed in August validated the Global Observer wing at its load limit.

AV is developing the Global Observer unmanned aircraft system (UAS) to be the first to provide robust, cost-effective and persistent communications and surveillance over any location. Six U.S. government agencies have provided funding for the JCTD program.

Global Observer is designed to address an urgent national security need for a persistent stratospheric platform and to offer a means to satisfy numerous high value civil and commercial applications. The system is intended to provide mission capabilities that include robust observation over areas with little or no existing coverage, persistent communications relay, the ability to relocate the system as required by theater commanders, dedicated communications support to other UAS and tactical on-station weather monitoring and data support. Because of its extreme endurance the Global Observer system can be based out-of-theater, reducing costs, supply chain requirements and potential risk to operational personnel.

Each aircraft in a Global Observer system is designed to fly at an altitude of between 55,000 and 65,000 feet for 5 to 7 days. In addition to flying above weather and above other conventional airplanes, operation in this altitude range means that sensor payloads on the aircraft will be able to view a circular area on the surface of the earth up to 600 miles in diameter, equivalent to more than 280,000 square miles of coverage.

Equipped with payloads that are readily available today, two Global Observer aircraft would alternate coverage over any location on the globe, making this the first solution to provide customers with practical, seamless coverage, wherever and whenever required.

AV is a technology company that designs, develops, produces and supports an advanced portfolio of Unmanned Aircraft Systems (UAS) and efficient electric energy systems. Agencies of the U.S. Department of Defense and allied military services use the company’s battery-powered, hand-launched UAS to provide situational awareness to tactical operating units through real-time, airborne reconnaissance, surveillance and target acquisition.

This certificate permits Dutch military personnel to operate Raven systems in designated Dutch airspace.

The AeroVironment Raven B system was selected by the Netherlands Ministry of Defence, acting through its Defence Materiel Organization (DMO), after performing an open competition in 2007.

Key elements resulting in its selection were hand-launchability, reliability, ease of use, robustness, and demonstrated in-theater operational performance and logistics support. The DMO subsequently purchased Raven B systems and support services, including training of military users.

"Receiving this MTC validates the Raven system's airworthiness and reliability, but also represents an important step toward the operation of small UAS in our national airspace," said Dick Goedhart, head section type management unmanned aircraft, DMO.

"This MTC also makes it possible for us to use Raven for non-military applications, though for those activities segregation of airspace must still be managed by procedures."

The Raven unmanned aircraft is a 4.2-pound, backpackable, hand-launched sensor platform that provides day and night, real-time video imagery for "over the hill" and "around the corner".

reconnaissance, surveillance and target acquisition in support of tactical units. U.S. armed forces use Raven systems extensively for missions such as base security, route reconnaissance, mission planning and force protection.

In addition to the Raven system, AV's small UAS include Puma AE(tm) and Wasp(tm), which are also hand-launched and controlled by AV's hand-held ground control station.

AV's UAS logistics operation supports systems deployed worldwide to ensure a consistently high level of operational readiness. AV has delivered thousands of small unmanned aircraft to date. In addition to the Netherlands
, international purchasers of Raven systems include Italy, Denmark, and Spain.

The demonstration at Camp Roberts, Calif. followed an inquiry from Pentagon officials regarding the potential for AV's Raven small UAS to perform low-cost, tactically relevant persistent surveillance.

The continuous 30-hour duration represents a prolonged tactical level surveillance mission similar to what would typically be performed at the battalion or lower level. Using one standard production Raven baseline system, which consists of three aircraft and two ground control stations, the demonstration provided continuous surveillance using only two-person crews operating in eight-hour shifts.

Employing the autonomous guidance capability incorporated into the Raven small UAS, operators rotated the aircraft over a surveyed point target, a residential building on the base, maintaining unbroken surveillance throughout the demonstration, and reported activity at the target site.

In addition to recording the imagery, the demonstration team streamed a live video feed from the operation via webcast throughout the event.

According to Dean Barten, product director for Army SUAS, "This demonstration indicates that the Raven small UAS is capable of performing tasks normally assigned to limited, high demand, and higher echelon reconnaissance assets in a highly cost-effective manner.

The Raven small UAS was employed and performed as it does everyday in combat operations - reliably, without fanfare, in support of the soldiers in the fight."

Barten said that in a testament to the Raven system's reliability, over the course of the 30-hour demonstration, 27 sorties were flown with no system failures or mission aborts. The system operated flawlessly, despite the presence of high winds, air turbulence and rain, all while operating out of an unimproved area.

"Soldiers have in their rucksacks an immediately accessible, long-term surveillance unmanned aircraft system to give them extended bird's eye views of a target so they don't have to wait for larger unmanned aircraft systems that are in high demand," said John Grabowsky, executive vice president and general manager of AV's UAS segment.

"The battle-proven Raven system could also support many important non-military applications for extended intelligence, surveillance and reconnaissance, such as border control, law enforcement, and communications and reconnaissance following a major storm."

In order to maintain continuous surveillance, the Raven system operators rotated the aircraft over the target: one aircraft operating on an alternate control channel would relieve the orbiting aircraft prior to the latter's rotation back to the launch/ recovery site.

The Raven system's daytime color electro-optical camera and nighttime infrared camera payloads were employed to ensure continuous situational awareness. The Raven system's operations were conducted in varying weather conditions, including rain and temperatures ranging from low 70's to mid 40's (Fahrenheit).

The Raven systems used by the Army include three air vehicles, day and night sensors, two ground control stations, a laptop computer with mission planning and recording software and accompanying spares and a battery charger. The 4.2-pound Raven aircraft is powered by lithium-ion batteries.

In addition to its Raven system, AV's small UAS product family includes Puma AE and Wasp, which are also hand-launched and controlled by AV's hand-held ground control station. Each aircraft in AV's family of small UAS is interoperable and tailored to address a variety of operational user needs.

AV's UAS logistics operation supports systems deployed worldwide to ensure a consistently high level of operational readiness. AV has delivered thousands of small unmanned aircraft to date. International purchasers of Raven systems include Italy, Denmark, the Netherlands and Spain.
