As many of your editor’s friends know, he is often lured to trolling the tabloids, looking for juicy bits about the royal family or Hollywood royalty.  Recently, while perusing the Daily Mail* for news of the upcoming Harry/Meaghan nuptials, he came across the big-headline news that three European power players – Rolls-Royce, Airbus, and Siemens, are collaborating on creating a testbed for a hybrid power system. The trio will take a Bae 146 four-engine regional jet, convert it to a hybrid demonstrator by 2020, and have a production plane in place by 2030.  The high-wing airplane has four turbofans in place now, but the partners will replace one with a Siemens two-megawatt electric motor powered by a Rolls-Royce two-megawatt generator …

Sitting next to your editor for the first day of CAFE’s ninth annual Electric Aircraft Symposium, Paul Bertorelli from AVweb, took copious notes, made sound recordings, and during coffee and lunch breaks and in after-hours sessions, interviewed the accomplished faculty at the Symposium.  His thorough and far-reaching reports appear in his last several days’ postings to AVweb.  Having stressed mightily while attempting to take understandable notes from each speaker’s talk, your editor can only be impressed by Paul’s super reportorial abilities, and his communicating the scope and importance of what took place at EAS IX. From your editor’s perspective, several significant things took place this year.  Senior leadership from Airbus and Siemens presented talks affirming their companies’ commitment to making …

Siemens Makes a Big, Light Motor

Its 14 kilogram (30.8 pound), 85 kilowatt (114 horsepower) motor already graces the nose of the PIpistrel WattsUp, and Siemens seems to have expanded its aeronautical offerings with its new 50 kilogram (110 pound), 260 kilowatt (348.5 hp.) unit.  According to Dr. Frank Anton, Head of eAircraft at Siemens Corporate Technology, the new motor “make[s] it possible to build series hybrid-electric aircraft with four or more seats.” Siemens claims a world record of five kilowatts per kilogram, although Roman Susnik, with his Emrax motors pulling close to 10 kilowatts per kilogram, might contest that, and LaunchPoint is working toward eclipsing that mark.  To be fair, it’s certainly a giant boost over the power-to-weight ratio of most industrial-type electric motors, which …

Dr. Brien Seeley, President of the CAFE Foundation, has made the following announcement: “The Chief designer of the F-22 Raptor has prepared another spectacular design: The World’s Fastest Electric Vehicle. This new aircraft design will be presented along with the other outstanding talks at next week’s CAFE Electric Aircraft Symposium, April 27, 28 in Santa Rosa, California (Sonoma Wine Country). This symposium, dedicated to the burgeoning new domain of emission-free flight, now has representatives from Boeing, Bosch, IBM, Honda, Nortrhop-Grumman, Japan Air Lines, Rolls-Royce, Siemens, Aerovironment, FAA, Cummins, Cessna, Lycoming and many other companies enrolled to participate.” The high-speed electric may be a response to Ivo Boscarol’s pledge to put up $100,000 of his Pipistrel G-4 winnings at last year’s …
