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 manufacturer headquartered in Changchun, Jilin.  Founded in 1953, it is currently the second largest of the “Big Four” state-owned car manufacturers of China, together with SAIC Motor, Dongfeng Motor Corporation and Changan Automobile.” e-Flight Journal reports the engine is “turbocharged …

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 nanocrystalline substance is part of a soft amorphous metal matrix.  Unlike traditional iron materials in motors, however, Aeroperm does not exhibit iron’s normal “lossiness.”  Instead, it loses energy at “one-tenth the rate of existing magnetic materials used in current electrical …

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 of those revenue-producing seats, Universal’s Plug Power containers taking up the back rows of the cabin.  Other gear included a rigorous evaluation of every component and system, the Dash 8 was ready for taxiing and test flights. Two large hydrogen …

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 controllable.  Remotely controlled  crashes, as shown in this2022 MK3 race, are no more harmful to human operators than a video game – although probably more costly. Looking a great deal like a Formula 1 or Formula e race car, the …

Air New Zealand has a five-part plan for reducing and even eliminating aviation emissions with some well-defined approaches and goals.  The airline hopes to achieve net zero by 2050, with demonstrable steps toward that starting now. Five Key Elements ANZ will rely on five key elements in its quest for zero-emission flight.  They are already involved in producing sustainable aviation fuel (SAF), partnering with makers of zero emission aircraft technologies, renewing their fleet, reducing carbon emissions through improved flight and ground operations, and removing carbon using best known techniques.  You can read the full sustainability report here. Producing SAF Sustainable aviation fuel (SAF), explains Air New Zealand, “Is made from a variety of sustainable resources other than crude oil, such as used cooking oils, landfill waste, forestry waste, carbon captured from the air and green hydrogen. It has the potential to dramatically reduce lifecycle carbon emissions by up to 80 percent or more compared with traditional jet fuel.” Since New …

H3 Dynamics and Its Hydrogen-Electric Nacelle

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

H3 Dynamics (formerly HES – Horizon Energy Systems) has flown a small example of its hydrogen-electric nacelle that could power many craft now in the concept phase.  H3 headlines its web page with the words, “Dreaming Big,” followed by the premise, “The future of aviation is hydrogen-electric, autonomous, and digital.”  Their press release declares, “The future of hydrogen aviation powered by H3 Dynamics’ distributed hydrogen propulsion nacelles has taken flight for the very first time in France.” Hydrogen could be a dream fuel, clean burning and leaving only a little water vapor in its wake.  It has a few drawbacks, though.  H2 takes up four times the space of gasoline or kerosene for a roughly equivalent amount of energy.  In something sizeable like a semi-truck or a seagoing ship, such space requirements can be accommodated.  Airplanes need to be streamlined and svelte, so trying to carry enough energy for long ranges and endurance can spoil otherwise beautiful lines. H3 claims its …
