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 …

Nudging, Then Doubling an Electric Distance Record

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

Suddenly, we’re seeing new electric aircraft nudging, then doubling an electric distance record.  First, Autoflight in China and then Beta in America achieve higher ranges than that previously achieved by Joby. Jules Verne Saw It Coming In two late 19th-century novels, Robur the Conqueror and Master of the World, Jules Verne chronicled the fictional adventurers of a mad inventor who thought he could dissuade world leaders from practicing war by bombing them from his Albatross flying warship.  A great deal like Captain Nemo of Nautilus fame, Robur uses violence to stop violence.  Both protagonists fail in their efforts. The Albatross, mistaken as its objectives were, is perhaps an inspiration for today’s eVTOLs, propellers spinning for lift and for forward motion.  …

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 …

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 …

Alauda AirspeederMK4  and  AMSL Speed Toward Records

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

Alauda and AMSL – two companies down under – are pressing ahead on divergent missions, but both powering “flying cars” with hydrogen.  Both craft will achieve higher speeds and cover longer ranges than most other electric Vertical Take Off and Landing (eVTOL) craft. Alauda Airspeeder MK4 Alauda’s brief history of creating Airspeeders hits its latest iteration, the MK4.  It replaces batteries with a 1,000 kilowatt hydrogen-fueled turbo generator driving ducted fans in place of previous open rotors.  Up to now, the various Marks were remotely controlled and battery powered.  MK4s will be “crewed” and powered by green hydrogen. Evolved over the last few years, MK4 will be much faster than its 100 kilometer per hour predecessors, and we hope, more …

Enovix BrakeFlow™ Stops Thermal Runaway

Dean Sigler Batteries, Sustainable Aviation Leave a Comment

Enovix battery architecture including its exclusive BrakeFlow™ system enables 100-percent silicon in their silicon/lithium electrodes and prevents battery fires.  Battery fires, particularly on or in an airplane, are potential disasters.  One such incident occurred recently on United Air Lines flight 2664 planned from San Diego International Airport to Newark New Jersey’s Liberty International Airport. Things went awry when a battery pack in the passenger compartment started to smoke and caught fire.  Seven passengers were injured, four of whom were hospitalized.  The Boeing 737 Max 8 was just starting its flight, turned around, and landed back at San Diego after only 10 minutes in the air.  Taxi times were greater than the flight time.  It was probably more than a bit …

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 …

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 …
