Heart Aerospace, a Swedish startup, has teamed with BAE Systems, a veteran British aerospace supplier, to help with powering its 30-seat, battery-powered airliner. The four-motor craft will include a very large battery pack under the passenger compartment. The need for safety should be obvious. Adding eleven seats to its original 19-seat platform, Heart also brings a turbo generator on board, enabling flights up to 400 kilometers (250 miles) with 30 passengers, or even 800 kilometers (500 miles) with 25. These figures include normal airline range reserves. Partners include BAE Systems, Swedish aerospace group Saab, avionics supplier Garmin, and Aernnova, a Spanish airframe specialist. BAE’s UK-based group’s Controls and Avionics Solutions operation in upstate New York will oversee the batteries and …
China Flies RX4HE, a Hydrogen-Powered Four Seater
China has flown its first hydrogen-powered four-seat aircraft, the Liaoning Ruixiang RX4HE, on March 25. The airplane is somewhat unique in having an internal combustion engine (ICE) that runs on the liquid hydrogen used as fuel. Developed with the FAW (First Automobile Works), the engine displaces two liters and runs on the 4.5 kilograms (9.9 pounds) of highly-pressurized H2 carried on board. This enables one hour endurance at a cruising speed of 180 kilometers per hour (112 mph). FAW claims 43-percent efficiency for the powertrain and an overall thermal efficiency “greater than 40 percent.” (The video shows the RX4E, no videos of the HE model yet available.) According to Wikipedia, “China FAW Group Corp., Ltd. is a Chinese state-owned automobile …
Amprius Announces 500 Watt-Hour per Kilogram Cell
Amprius has announced a 500 Watt-hour per kilogram cell, essentially doubling the energy density available up to now. Remember, though, that cell-levels of energy drop as the cells are incorporated into modules and packs, carrying the burdens of containment packaging, bus bars, and battery management systems (BMS) that lower total output. Pack levels will be lower. Slow Progress This comes as the culmination of at least 14 year’s work, starting with Yi Cui’s work at Stanford University. Your editor first saw him at a 2009 CAFE Foundation symposium at the Hiller Aviation Museum in San Carlos, California. He was a proponent of the 10X battery, which at that time would have meant 10 times the energy storage of then typical …
Monash Makes Motors – and Fuel from Thin Air
Monash University announced a new type of electric aircraft motor and the promise of a fuel that could power everything from your smart watch to your airplane in the future. Both rely on unique ways of seeing the physical world around us. The Kite Magnetic Motor Charles Alcock, writing for FutureFlight.com, discusses Kite Magnetics’ 120 kilowatt (160 horsepower) electric propulsion unit (EPU) intended for a variety of light aircraft applications. part of a program at Monash University in Melbourne, Australia, the motor could find applications in “conventional fixed-wing aircraft, as well as eVTOL and eSTOL designs, high-altitude satellites, and wing-in-ground craft,” according to the University. At its core, the motor relies on the University’s patented Aeroperm™ magnetic material. This lightweight …
APUS Offers Two Hydrogen-powered Aircraft
Designs to Fly “Without Harm for the Climate” APUS (Latin for swift bird) has announced two aircraft, the i-2 and i-5, that will offer either zero emission or very low emission flight. The designs represent some highly innovative thinking and excellent performance. APUS states its mission as, “Flying without any Harm for Climate!” To that end, they are developing four craft that will fly on green hydrogen power. Partnered with, “PowerCell (Hydrogen Fuel Cells), Fraunhofer (High-Voltage applications), COTESA (hydrogen storage solutions) and HEGGEMANN (hydrogen supply and safety systems) we are developing certified powertrain units for emission-free air transportation applications.” APUS i-2, Zero-Emission General Aviation Aircraft In a recent discussion with CEO Dipl.-Ing.Phillip Scheffel; Laurent Altenberger ,an Aerospace Project and Supply …
Biggest yet from Universal Hydrogen
Universal Hydrogen flew the largest hydrogen-powered aircraft yet at Grant County Airport in Moses Lake, Washington. The DeHavilland Dash 8 was powered on its right side by a MagniX motor and fueled by H2 from a pair of containers in the rear of the fuselage. It made a 15 minute flight to 3,500 feet and settled back to a safe landing It carried “the largest hydrogen fuel cell ever to power an aircraft, “and Universal Hydrogen co-founder and CEO Paul Eremenko “declared the moment the dawn of a new golden age of aviation.” Prep for flight Lightning McClean, Universal’s modified Dash 8, normally flies with up to 50 passengers. The penalty for using H2 for fuel is giving up 10 …
Universal Hydrogen Certified, Ready to Fly
On February 7, 2023, Universal Hydrogen received a Special Airworthiness Certificate in the Experimental category from the Federal Aviation Administration. This will allow their DeHavilland Dash 8-300 to begin test flights. Universal boasts their craft will be the largest hydrogen fuel cell-powered aircraft ever to fly. Up to now, it’s been performing taxi tests and motor runups, getting ready for the big day. On a Mission Universal Hydrogen’s web site opens with this statement: “Our mission is to put aviation on a trajectory to meet Paris Agreement emissions targets by making hydrogen-powered commercial flight a near-term reality.” The coming flight tests are a major step toward fulfillment of that mission. Inclusion of the large hydrogen-carrying modules reduces passenger carrying capacity …

Elektra Trainer Certified
Calin Gologan has been in the electric and solar-powered airplane business for a long time. Displaying and flying his Elektra One at Oshkosh, Wisconsin in 2011, he was early to the game. Now, with the his Elektra Trainer certified, relatively inexpensive flight training is imminent. Birgit Weissenbach announced the June 29 maiden flight, subsequent test flying, and January 19, 2023 certification of Elektra Solar’s two-seat, side-by-side trainer. In a 20-minute flight from Memmingen International Airport, taking off in less than 100 meters (328 feet), the craft confirmed “the extraordinary characteristics of the aircraft, which even exceeded the expectations of the developers.” Certification came from DULV (Deutschen Ultraleichtflugverbandes, or German Ultralight Association), as the representative of the Federal Ministry for Digital …
Carbon and Oxygen and Dirt Cheap Batteries
Carbon and oxygen comprise a big part of the universe, and are essential to life on earth. They may also be the answer for long-term energy storage in a promising battery development from Noon Energy. “100 hours of storage at one-tenth the cost of lithium-ion batteries for long-duration storage.” It started on Mars According to Electrek, “Chris Graves, Noon Energy’s founder and CEO launched the company in 2018 After helping to develop NASA’s Mars Perseverance rover MOXIE device, which produces oxygen from the Martian carbon dioxide atmosphere.” According to TechCrunch, “The device sucks in carbon dioxide and strips off an oxygen atom, which it stores on board. The remaining carbon monoxide is exhausted into the thin Martian atmosphere. MOXIE, by the …
