Dean Sigler Announcements, Batteries, Electric Powerplants, Hybrid Aircraft, Sustainable Aviation Leave a Comment

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

Dean Sigler Announcements, hydrogen, Hydrogen Fuel, Sustainable Aviation Leave a Comment

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

Dean Sigler Announcements, Batteries, Sustainable Aviation Leave a Comment

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

Dean Sigler Announcements, Batteries, Electric Powerplants, hydrogen, Hydrogen Fuel, Sustainable Aviation Leave a Comment

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 …
