ONERA’s AMPERE Flies on Distributed Electric Thrust

Dean Sigler Electric Aircraft Components, Electric Powerplants, Fuel Cells, Sustainable Aviation 0 Comments

ONERA’s mission statement for its AMPERE (Avion à Motorisation réPartie Électrique de Recherche Expérimentale) electric aircraft is fairly straightforward.  “AMPERE is a demonstrator of a regional airplane with electric propulsion distributed, allowing to transport from 4 to 6 people over 500 [kilometers – 310 miles] in 2 hours.  The objective of the AMPERE project is to bring to maturity the technology of distributed electric propulsion in order to transfer it to the industry.”  ONERA, the Office National d’Etudes et de Recherches Aérospatiales (National Office for the Study and Research of Aerospace) is the French equivalent of NASA. ONERA showed a one-fifth-scale model of AMPERE at the Paris Air Show last week, with spokesman and designer Jean Hermetz holding forth on …

Long Hours of Droning On

Several different organizations are trying different ways to keep unmanned aerial vehicles, UAVs, up longer.  We’ll look at three recent efforts in long-endurance missions, each with a unique technological approach. Wirth Research – Hydrogen Fuel Cell Wirth Research is now constructing a new tilt rotor, Vertical Take Off and Landing (VTOL), hydrogen fuel cell powered, advanced terrain-mapping drone.  Carrying a payload of sensors and onboard data processing capabilities, the vehicle will be powered by a complete H2 storage, control and power system provided by HES of Singapore, a specialist in ultra-light hydrogen fuel cells. The Wirth machine’s missions range from precision agriculture, to pipeline and cable inspection for utilities, surveillance and other security-related tasks, through to detection and monitoring support …

April 21 and 22, 2017, set your GPS for N 37° 31′ 20.84” W 122° 15′ 38.31” – the Hotel Pullman San Francisco Bay.  The refined and beautiful setting and four-star accommodations make a grand accompaniment to the story we will share. The story of the 2017 Sustainable Aviation Symposium includes the latest in aerodynamics, electric power and energy storage.  It’s a grand and sweeping review, told by talented intellects in the context of using the latest technology to help save the planet.  A few exemplars of the program highlight this year’s story, “ A Keynote Address from a Master Designer Tine Tomazic, Director of Research and Development for Pipistrel, created the G4 to win the 2011 Green Flight Challenge, …

HY4 Makes First Public Flight – Your Editor Rides EAA’s Ford Trimotor

A day after Pipistrel, the DLR and associates flew the first public demonstration of their four-seat hydrogen-powered HY4, your editor and a friend took a brief hop around the Aurora State Airport in Oregon in EAA’s Ford Trimotor, the first certified airliner in America.  The two events, roughly equal in duration, if not in historicity, demonstrate a readily observable progress in aeronautics. A quickening of design and technology 14 years after the Ford 5AT first flew on a scheduled route that took 51 hours total time to cross the United States (and split transport duties with trains), your editor’s father was whisked nonstop by Army Air Corps C-54 across the Atlantic to Shannon, Ireland, and then to Bobbington and Newquay, England …

Dr. Joseph Kallo, DLR See a Hydrogen Future

Speaking at the first annual Sustainable Aviation Symposium at the Sofitel San Francisco Bay on May 6, 2016.  Dr. Joseph Kallo focused on hydrogen as a more than potential fuel for future flight.  He stressed that H2 fuel development was further along than one would think, and shared several examples to promote that thought. A Busy Man, a Storied Airframe Dr. Kallo is DLR (Deutsches Zentrum für Luft-und Raumfahrt – German Center for Air and SpaceTravel) Coordinator of Electrical Aviation for Germany’s equivalent of NASA, oversees work at the DLR Institute of Engineering Thermodynamics, which has worked with Pipistrel in Slovenia to convert the Green Flight Prize winning Pipistrel G4 to the hydrogen-powered HY4. He’s also Institute Director at the …

Nissan’s SOFC Vehicle – Just in Time for the Olympics

Dean Sigler Biofuels, Fuel Cells, Hydrogen Fuel, Sustainable Aviation 0 Comments

Two major types of fuel cells vie for vehicle designers’ attention: PEM, or proton exchange membrane types, and solid oxide fuels cells (SOFCs). PEMs (also known as polymer electrolyte membrane fuel cells) require an expensive catalyst such as platinum, and hydrogen as fuel. Hydrogen itself is costly to produce and runs up the operating cost for such a fuel cell. Nissan Motor Co., Ltd. timed things to coincide with the 2016 Olympics opening in Rio de Janeiro, Brazil for the introduction of their solid oxide fuel cell vehicle, a van that runs on bio-ethanol electric power.  Nissan’s Carlos Ghosn claims this to be a first, with benefits for potential users. “The e-Bio Fuel-Cell offers eco-friendly transportation and creates opportunities for …

Roof Top Hydrogen-Generating Solar Cells for Vehicles

Students at the University of Leuven, the Netherlands, have won the first Energy Award, sponsored by Febeliec – the association of industrial energy consumers, a Belgian trade association. Their miniature solar panel produces hydrogen gas when exposed to sunlight, not unlike “artificial leaves” of other researchers.  The bioscience engineers crafted a small square panel that can be mounted to rooftops, including those of cars, to convert water vapor in the air to H2 that could feed fuel cells in the building or vehicle.  This could also reduce CO2 “on a large scale to convert it into useful substances,” according to the team of young scientists. Generating electricity and producing hydrogen at the same time is a neat trick, but the …

EnergyOr Ups the Ante for Endurance

Staying airborne for more than an hour or two might seem like a huge leap for battery-powered electric aircraft.  Inspired designers like Eric Raymond have been able to use solar cells to extend their flights to near-perpetual states.  A large craft like Solar Impulse 2 remains in flight for up to five successive days and nights only through careful energy management and flight planning.  Researchers are looking at hydrogen fuel cells as an alternative to batteries, with the hopes of achieving greater endurance. One company, EnergyOr, has developed two still small fuel cells to power their rotary- and fixed-wing drones, setting several records in the process.  With payloads and maximum takeoff weights that enable carrying a 4K camera or large …

Fuel Cells for Drones: Going for Endurance

Dean Sigler Fuel Cells, Hydrogen Fuel, Sustainable Aviation 0 Comments

Several fuel cell developments show there are lots of options for burning hydrogen, if we can only make and distribute it in great enough quantities.  Most noteworthy, fuel cells could provide increased endurance and range compared to batteries. Professor Gyeong Man Choi and his Ph.D. student Jun Joong Kim, working at the Pohang University of Science & Technology (POSTECH) in South Korea, have developed a miniaturized solid oxide fuel cell (SOFC) that can fly a drone for more than an hour.  On the consumer front, their fuel cell would allow cell phones to be charged just once a week. The professor and his students created the fuel cell to directly replace the batteries normally found in cell phones, laptop computers, …
