Our guest explains the research on fuel cells as a power source for unmanned aircraft. In the news, an Airobotics drone operates without a human pilot, the USAF uses a drone for aircraft inspections, BVLOS inspections in Canada, an underwater autonomous vehicle, a drone for humanitarian missions, more Amazon UAS patents, and a Patriot missile takes out a small quadcopter.
Dr. Benjamin D. Gould is a Chemical Engineer in the Chemistry Division of the Naval Research Laboratory (NRL). He’s an expert in fuel cell power systems and specializes in the development of next-generation power sources for the US Navy.
We talk with Dr. Gould about the research the NRL is conducting with fuel cells and the Ion Tiger unmanned air vehicle. We learn how fuel cells produce electricity, and the reasons fuel cells are attractive for unmanned aircraft. Dr. Gould also explains the application of additive manufacturing to fuel cells, future research projects, and the availability of the hydrogen used as the fuel.
Dr. Gould earned his Ph.D. in Chemical Engineering from the University of Michigan in 2007 and his B.S. in Chemical Engineering from the Colorado School of Mines in 2002. His research interests include additive manufacture of fuel cells, fuel cell recovery processes, bipolar plate design, open cathode fuel cells, and hydrogen safety. He was awarded the prestigious 2013 Delores M. Etter Top Scientists & Engineers of the Year Award for his work on fuel cells.

Tel Aviv-based Airobotics wanted to build a drone that required no human operator. One that could take off, fly pre-programmed flights for up to 30 minutes, and then land without human assistance. The company now says they have “developed a platform that is fully automated, industrial grade, on-demand and multi-purpose.” The Airobotics 1 video shows the automated landing box and a robotic arm for automatic payload and battery exchange.
A quadcopter has been tested for the maintenance inspection of a C-17 cargo plane at Edwards Air Force Base. The US Air Force’s 412th Test Wing’s Emerging Technologies Combined Test Force (CTF) flew three sorties on the flight line with a 3D Robotics Solo quadcopter. Next, they’ll analyze the video to determine if the resolution is good enough to see small details like structural abnormalities, rivets, and cracks.

Canadian UAVs Inc. and Lockheed Martin CDL Systems are teaming for BVLOS inspections of pipelines, wellheads, and power lines. Using a Lockheed Martin Indago 2 quadrotor, they demonstrated the capability at the UAV testing facility in Foremost, Alberta.
Canadian UAVs Inc. is a UAV solutions provider. Lockheed Martin CDL Systems specializes in the development and licensing of vehicle control station software for unmanned systems.
“Boaty McBoatface” is a British UAV, an underwater autonomous vehicle. Researchers plan to use it to collect data about the effects of global warming on the world’s oceans. Boaty is to depart from southern Chile and head towards the Southern Ocean. Follow @BoatyMcBoatface on Twitter.
Windhorse Aerospace is developing a prototype of the Pouncer delta-wing drone. This single-use drone is designed to carry food and supplies on humanitarian missions. Windhorse says it’s “pre-formed shell can be reused to provide shelter, the frame can be burnt safely to cook food, and the payload, which is food and water, provides life-saving nutrition.” Not only that, but the company says, “One day, the airframe may be made of edible components.”
If a drone lands on a sloping surface, it could fall over. But an Amazon patent contemplates independently telescoping legs that would allow it to stay level. Such legs could also act as a shock absorber, and be tipped with spikes, screws, suction cups, or magnets to grip different surfaces. Another Amazon patent shows adjustable winglets on propeller tips for flight efficiency.

Gen. David G. Perkins, commander of the US Army Training and Doctrine Command, speaking at the 2017 Association of the United States Army (AUSA) Annual Meeting & Exposition, stated that someone described as a very close U.S. ally “dealing with an adversary flying a small quadcopter,” fired a Patriot surface-to-air missile at the drone. It worked.
