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 …
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 Peter make his determination on that. Note the machine seems to be remarkably quiet, the OpenPPG motor drowned out by propeller noise. (That’s also low because of the e-Prop’s design.)* When Peter is able to shout down to his father …
