MagniX, an Australian High-Power and Torque-Dense Motor

A new motor from Australia, the MagniX Magni5, promises 300 kilowatts (402 horsepower) from a 53-kilogram (116.6-pound) package, or about five kW per kilogram.  This is competitive with other power-dense permanent magnet motors. The Magni5 claims an absolutely flat torque curve (more a line, really) from zero to 2,500 rpm, producing 1,000 Newton-meters (737.5 foot-pounds) throughout its revolution range.  This is a great deal like steam locomotive performance.  Its 444 millimeter (17.5 inches) diameter and 275 mm (10.8 inches) size is perfect to hide behind a propeller spinner.  The torque should guarantee a good rate of climb, and might be a worthy candidate for powering a Pikes Peak International Hill Climb contender. The company certainly seems to be on track …

EADS’ Electrifying Threesome at Paris Air Show

EADS (European Aerospace Defense Systems), known colloquially as Airbus, highlighted its Paris Air Show chalet at Le Bourget with three  examples of the work from its Innovations Workshops. All projects are part of the European Commission’s “Flightpath 2050” initiative, conceived to reduce carbon dioxide (CO2) emissions 75 percent, nitrogen oxide (NOx) emissions 90 percent and noise  65 percent from 2000 levels by 2050. EADS thinks electric and hybrid propulsion could become an alternative to fossil fuels within that timeline, with several projects highlighting, “the willingness of EADS to invest in technologies that today, tomorrow, will further reduce emissions of carbon dioxide from aviation.” E-FAN Working with Aero Composites Saintonge (ACS), the IW Research and Technology Group has developed and built the …
