Global Observer's maiden hydrogen-powered flight (USAF)

Following on from a successful maiden flight under battery power in 2010, AeroVironment’s high altitude, long endurance (HALE) Global Observer unmanned aircraft has now taken to the skies using hydrogen-fueled propulsion. The aircraft reached an altitude of 5,000 feet during the four hour flight on January 11 at Edwards Air Force Base (EAFB) in California. Both the endurance and the altitude of the system will be expanded in further test flights in order to achieve the planned operational altitude of 55,000 to 65,000 feet.  Read More

Global Observer takes to the air for the first time

After AeroVironment’s recent announcement that its Global Observer unmanned aircraft system (UAS) had successfully completed a series of Wing Load tests the team apparently wasted no time getting the craft in the air for its maiden flight. On August 5 Global Observer 1001 took off from Edwards Air Force Base (EAFB) in California and climbed to an altitude of 4,000 feet where it performed a series of maneuvers before landing successfully one hour later.  Read More

Global Observe has completed a series of Wing Load Tests at NASA's Dryden Flight Research ...

AeroVironment has passed a critical milestone in the development of its Global Observer unmanned aircraft system (UAS). The company reports that the High Altitude Long Endurance (HALE) aircraft has completed a series of Wing Load Tests at NASA's Dryden Flight Research Center – proving that the aircraft's all-composite 175-foot wing can withstand the level of dynamic stress it will be subjected to at altitudes of between 55,000 and 65,000 feet.  Read More

AeroVironment eyes new EV Fast-charging Benchmark: 80% in 15 minutes

One of the key stumbling blocks in the uptake of battery electric vehicles is charging times. After all, who wants to wait eight hours to "fill the tank" when a gasoline, hybrid or hydrogen powered vehicle can be replenished in a matter of minutes. One of the projects seeking to address the issue is a collaboration between electric vehicle manufacturer THINK and charging infrastructure developer AeroVironment (a company best known to Gizmag readers as a manufacturer of UAVs). The companies are collaborating on a fast charging project for the THINK City electric vehicle with the goal of taking the EV from zero charge to 80 percent full in just 15 minutes.  Read More

AV has released video of its hovering Nano Air Vehicle

Not long ago we brought you an article about a tiny ‘nano air vehicle’ (NAV) that hovers by flapping its wings. Its creator, AeroVironment, has now released a video capturing details of the craft's impressive non-restricted flying capabilities.  Read More

Aeropak fuel cell provides four times the power of advanced lithium batteries

Horizon Fuel Cell Technologies latest hydrogen fuel cell release is designed as a drop-in replacement for battery packs used in small electric Unmanned Aerial Systems (UAS). Weighing 4.4lbs (2kg) and storing 900Wh of usable electric energy, the Aeropak can to increase flight endurance by up to 300% over lithium batteries, meaning longer range missions and more energy to run on-board cameras and sensors.  Read More

Raven UAV

AeroVironment's Raven UAV system has been used to demonstrate the viability of small Unmanned Aerial Vehicles as a low-cost surveillance alternative in a continuous 30-hour persistent surveillance test flight. Conducted in conjunction with the U.S. Army Product Manager for Small Unmanned Aircraft Systems (SUAS), the demonstration involved unbroken surveillance of a target site using one standard production Raven RQ-11B baseline system (three aircraft and two ground control stations) operated by two-person crews working in eight-hour shifts.  Read More

AeroVironment's Raven UAS: new Digital Data Link

AeroVironment, Inc. will produce 50 new Raven RQ-11B unmanned aircraft systems (UAS) equipped with enhanced communications following the announcement of a USD$16.8 Million order from the U.S. Army on January 22. The company's new Digital Data Link (DDL) replaces the original four-channel analog set-up, increasing communication channels by a factor of four and allowing more of the unmanned craft to be flown in one area simultaneously.  Read More

The Windspire

While wind turbines are a clean, green way to generate power, they can be a bit of an eyesore and require quite a bit of room meaning, more often than not, they need to be located in sparsely populated areas far from where the generated power is actually needed. We’ve looked at AeroVironment’s innovative urban solution as well as StatoilHydro’s HyWind. Now a look at another innovative product - Windspire. The Windspire, from Reno, Nevada based Mariah Power, combats the large footprint problem by employing a propeller-free design that makes it ideal for rural, suburban, and even some urban residential environments.  Read More

UM SolarBubbles team with 'Endurance'

Fuel-cell manufacturer Adaptive Materials and students from the University of Michigan have teamed up to set a new world record for the longest fuel-cell-powered flight of a radio-controlled aerial vehicle. The flight of 10 hours, 15 minutes and four seconds beats the previous mark of just over nine hours set by AeroVironment's Puma UAV earlier this year.  Read More
