Airbus announced its Zero E program in late September, showing three possible candidates for hybrid hydrogen power. Zero E, for zero emissions, is a tall order even for one of the world’s two largest aircraft companies. Now, the company makes yet another announcement – for a novel modular “pod” configuration – “a stand-alone propeller propulsion system powered by hydrogen fuel cells. It consists of the following elements:” A propeller Electric motors Fuel cells Power electronics LH2 tank A cooling system A set of auxiliary equipment Instead of housing the hydrogen fuel in the fuselage, Airbus creates a more spacious cabin by moving fuel storage to each pod. Each pod would be identical and modular. Components could be removed and replaced …
Something to Lighten the Post-Holiday Letdown
Even following Boxing Day, we have a few items to re-gift to our faithful readers, and close out the season with four very light examples of electric aviation. A-I-R ATOS Felix Ruhle has been improving and refining a basic wing design for over a decade, growing a line of aircraft that range from simple hang-gliders to fairly sleek, self-launching, electrically-powered ultralight sailplanes. The A-I-R factory/showroom in Halblech, Germany, one of 18 dealerships around the world, fronts a lush green meadow and houses a plethora of ATOS wings. The ATOS wing, coming in a range of sizes, can be attached to seemingly anything from a simple jump-off-the-nearest cliff hang-gliding rig to refined, electrically-powered ultralight sailplanes. Under development for the last few …
Beam Me Up: Flying on Sunshine™
We recently reported on two electrically-powered cross-country flights for which the big issue was lack of battery-charging facilities at airports along the way. Both “teams” had their chargers carried by an accompanying airplane or automobile. Now, with a public demonstration a Beam Global charger at Reedley Municipal Airport in Fresno County, California, we see a no-fuss way to bring EV charging to aviation – even in remote locations. Beam Global premises its installations on a foursome of negatives: No permitting, no construction, no electrical work, and no utility bill. Installation, if one believes Beam’s video, is almost a non-event. Beam, formerly Envision Solar, produces pre-fabricated EV ARC solar-powered charging stations. Like a vacation camper, the ARCs can be towed right …
Peter Sripol’s Mk. IV is Paramotor Powered
Peter Sripol creates interesting ultralight aircraft, among other, sometimes scary projects. His latest is pulled along by a paramotor motor. Because of the small aircraft’s low and slow performance, the low-power (and very low noise) motor seems more than sufficient to the task. His fourth design, the Mk IV has no ailerons, much like an earlier ultralight, the Skypup. After initial tests showed shortcomings with the Mk. IV, quickly modified wings allowed Peter to return to the air quickly. As he explains, there won’t be plans for this airplane because it has too many not as yet time-tested innovations. The hot-wire-cut foam structure and vinyl wrapped wings are an unknown in terms of longevity, so it’s probably best to let …
NAWA’s Straight Line Electrode to More Power
Most battery breakthroughs are five years in the future, following the basic rules of scientific journals and Popular Science magazine. The usual refrains are, “Further research is required,” and “Researchers expect commercial development within the next decade.” Rather than wait for the future, NAWA Technologies claims the world’s fastest electrode today and production now. NAWA’a brochure explains their Vertically Aligned Carbon NanoTube (VACNT) architecture is “key to its next-generation energy storage.” Think of a forest of carbon nanotubes through which current can flow. In the jumble of usual battery materials, an ion would have to clamber over boulder-like obstructions and possibly get hung up in the random intersections of conductive material. The VACNT architecture allows ionic flow as though they …
A Dash of Hydrogen
Getting the Parts Free, Charged for Refills What if future flight had a simple “return the old fuel container and get a new one” business model? Paul Eremenko, founder of California startup Universal Hydrogen, wants to try it out in a Dash 8 airliner equipped with two 2-megawatt motors supplied by MagniX. Poor analogy perhaps, but in his boyhood, your editor had a camera that was sold at the store complete with a roll of film already inside. All you had to do when you took all your pictures was send it by mail, with a check or money order, and a week later, you got the reloaded camera back with the prints and negatives of your pictures. This klunky, …
ZeroAvia First Out of the Gate with Hydrogen Flight
An Historic Hydrogen Outing While Airbus and MagniX promote the near- and not-so-near virtues of hydrogen-powered flight, ZeroAvia has demonstrated such flight with the largest H2-powered aircraft so far. Their Cranfield, England-based Piper Malibu flew on H2 power for the first time September 24 on an eight-minute circuit. The blue Malibu reached 1,000 feet and a top speed of 100 knots true air speed. Quick to capitalize on the successful mission, , ZeroAvia founder and CEO Val Miftakhov held a press conference the next day. In it, he explained his team,“has had discussions with seven aircraft manufacturers about possible retrofit and new-build applications for the propulsion system. He said the company has signed letters of intent with 10 airlines that …
Eather One – When Friction is a Good Thing
Tribolectrics Your editor has long promoted the idea of the Grand Unified Airplane, a vehicle which would essentially power itself from sunlight, piezoelectrics, structural batteries, and even the friction of the air over its surfaces. He wrote about the concept in the May, 2013 Kitplanes, and has noted an increasing number of articles in scientific journals describing a variety of nanogenerators, including tribolectric types. Tribolectrics are not new, having been discovered in the 18th century and initially quantified by Johan Carl Wilcke, a Swedish Physicist in 1757. “Tribo” comes from the Greek for “rub,” and as shown in the following video, even the rubbing of air over a surface can generate electricity. Note that about the 1:25 point Dr. Wang …
Two New Electric Sailplanes
Two electric sailplanes come from different ends of the soaring spectrum and each shows its own unique character. Their differences are as noteworthy as their geographic separation. Birdy Birdy is a single-seat, electrically powered motor glider that fits the European Union 120 kilogram class. The 264-pound empty weight puts it 10 pounds above America’s FAA Part 103 254-pound limit. But Euro craft in that category are not as limited in top or cruise speed. Birdy’s light weight required clever arrangement of components to enable a maximum takeoff weight of 280 kilograms (616 pounds) and pilots up to 1.95 meters (6’ 5”) tall. Its 13.5-meter (44.29-foot) wingspan carries only 13.9 pounds per foot, enabling 40:1 glide ratio at around 90 kilometers …
Pipistrel Velis: Part of an Electric Heritage
The Pipistrel Velis is the culmination of 13 years of electric aircraft development and the first to gain certification by the European Union Aviation Safety Agency (EASA) on June 10. Pipistrel has been in the electric airplane business since 2007 when it announced the Taurus Electro motorglider, which entered service in 2011. That aircraft went through several iterations, and is still part of the Pipistrel lineup of electric planes, which includes the Alpha Electro Trainer, the Panthera Hybrid, and the new Velis. Alpha Electro Trainer in SoCal An electric version of the Alpha Trainer, the Electro has been in production since 2015. With an empty weight of 615 pounds (279 kg) and a maximum take-off weight of 1,212 pounds (550 …
