UAS

DARPA researchers have ruggedized a compact solid oxide fuel cell fueled by propane and in...

Small unmanned aircraft systems (UAS) have become an increasingly important intelligence, surveillance and reconnaissance tool for the military and their use will only continue to expand. While vehicles that are small enough to be carried provide soldiers in the field with capabilities such as over-the-next-hill imagery or the short-term monitoring of convoys, much research is going into finding ways to extend mission duration through better battery systems. DARPA researchers say they have overcome this limitation with the development of a compact solid oxide fuel cell (SOFC) fueled by propane that quadruples the endurance of small unmanned aircraft systems .  Read More

First flight for MP-RTIP equipped Global Hawk (Photo: Northrop Grumman)

Northrop Grumman's Block 40 Global Hawk has new eyes. The unmanned aircraft completed its first full system flight carrying the production version of the next-gen Multi-Platform Radar Technology Insertion Program (MP-RTIP) sensor at Edwards Air Force Base, California, on July 21.  Read More

Geocopter's GC-201

Quadrocopters like the AR.Drone and Datron Scout may have been hogging the UAS limelight lately but Dutch unmanned rotorcraft system manufacturer Geocopter has shown there’s still life in the traditional helicopter design yet with the official delivery of its first light unmanned helicopter called the GC-201. Designed and built just like a normal helicopter, the GC-201 features a twin gas turbine engine propulsion system, lightweight carbon fiber fuselage and full automatic takeoff, mission and landing capabilities.  Read More

Elbit has successfully tested an interesting new Forward Ground Control Station (FGCS) for...

Israeli defense technology company Elbit has successfully tested an interesting new Forward Ground Control Station (FGCS) for its Skylark I LE man-packable Unmanned Aerial System (UAS). The lightweight FCGS is 15 kg (33 lbs) lighter than the existing Skylark ground control system and is designed to enable dismounted soldiers to carry minimum gear for optimal operational efficiency, as the UAS can be launched by Dispatcher Units well to the rear, transferring control of the operation to the FGCS-equipped Forward Units when the UAS reaches their range.  Read More

Boeing Phantom Ray UAS takes off on its maiden flight (Photo: Boeing)

Boeing has successfully kicked-off its test flight program for the Phantom Ray unmanned airborne system (UAS). The fighter-sized technology demonstrator reached an altitude of 7,500 feet and a speed of 178 knots in its first flight on April 27 in the skies above NASA's Dryden Flight Research Center at Edwards Air Force Base, California. A second successful test flight followed on May 5.  Read More

The Firebird was designed to be flown either manned or unmanned

Although the use of unmanned aerial vehicles (UAVs) such as Global Hawk and Raven for military information gathering has increased sharply in the last decade due to the maturation and miniaturization of enabling technologies, conventional piloted aircraft can still be a better option depending on the mission at hand. Northrop Grumman has unveiled a new intelligence gathering aircraft called the Firebird that falls into the category of an Optionally Piloted Vehicle (OPV) with its ability to be flown robotically or with a human pilot on board.  Read More

The Global Observer before its maiden flight in August 2010

In a setback for AeroVironment's four-year demonstrator program, the first Global Observer unmanned aircraft system has crashed during flight-testing. AeroVironment has confirmed the "mishap" occurred at 2:30 am PDT on April 1st, approximately 18 hours into its ninth test flight at Edwards Air Force Base (EAFB) in California.  Read More

K-MAX unmanned helicopter sets payload record (Photo: Lockheed Martin)

The Unmanned K-MAX helicopter being developed by Kaman Corporation and Lockheed Martin has further demonstrated the potential of this type of aircraft in the field by completing a list of airdrop firsts. The milestones in payload weight and altitude were reached during a recent series of tests at the Army's Yuma Proving Ground in Arizona where the KMAX (UAS) made guided airdrops via sling load at an altitude of 10,000 ft above sea level including a payload of 4,400 lbs.  Read More

The pint-sized, lightweight Nano Hummingbird

AeroVironment, the California-based company behind the largest, highest and longest flying unmanned aircraft system (UAS), the Global Observer, has now achieved a remarkable technical milestone with a much smaller aircraft. With its "Nano Hummingbird" the company has for the first time achieved controlled precision hovering and fast-forward flight of a two-wing, flapping wing aircraft that carries its own energy source and relies only on its flapping wings for propulsion and control.  Read More

Skylark I UAV from Elbit Systems flies on AEROPAK fuel cell power in simulated battlefield...

The latest test of Horizon Energy System's AEROPAK fuel cell power system has seen it fitted aboard an Elbit Systems Skylark I-LE UAS (Unmanned Aircraft System) and put through its paces. Although the AEROPAK has been put to the test in other UAS aircraft, the official test flight recently carried out in Israel marked the first time a fully operational system using the AEROPAK - including take-off and recovery with an operational payload integrated onboard - has been tested.  Read More
