The following press release was distributed by Dr. Birgit Weißenbach, wife of Calin Gologan and press representative for PC-Aero GmbH: “Many press releases and articles were published in the whole world relating the Aircraft flown by Luminati Aerospace LLC in NY named Substrata V0 and the Solar Electric airplane from PC-Aero/Elektra UAS named Elektra One Solar. “In order to avoid misunderstandings PC-Aero/Elektra UAS GmbH publish[es] the following press release: “In October 2015 PC-Aero/Elektra UAS, the designer and manufacturer of the electric-solar airplane Elektra One Solar, and Luminati Aerospace signed a Manufacturing License Agreement for ONE UNIT aircraft based on the Elektra One Solar documentation provided by PC-Aero/Elektra UAS. PC-Aero/Elektra UAS also provided [a] ONE UNIT manufacturing license agreement to CarbonWacker GmbH …

Seventh Annual Electric Aircraft Symposium Unveils New Technology

Dean Sigler Electric Powerplants, Feedback, Sustainable Aviation 3 Comments

This year’s CAFE Foundation Electric Aircraft Symposium in Santa Rosa, California had surprises from several sources, including new aircraft, batteries, and materials that will help make the future a good place to be.  Some technologies are maturing and some are about to spring forth in ways we won’t see coming. We’ll be looking at each presentation in detail in future postings, but know for certain that the electric aircraft movement is turning a corner as things become integrated in an ever-quicker progression.  We will see significant announcements in the next few months. The Symposium included not only technology, but seriously looked at how neighborhoods and society in general can integrate these new technologies in a more responsible way than the …

Ionic Thrusters Offer Quiet Flight

Dean Sigler Electric Powerplants, Feedback, Sustainable Aviation 1 Comment

Gizmag and Science Daily both covered a propulsion system that’s been with us for many decades, but which is just now seeing practical applications in space flight, and may be adapted to terrestrial winged vehicles. Your editor might have passed it over as overhyped, but the research came from the Massachusetts Institute of Technology (MIT) and was published in The Proceeding of the Royal Academy – two good indicators of veracity. Jennifer Chu of MIT’s News Office explains, “When a current passes between two electrodes — one thinner than the other — it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel.”  That …

A Comparison Too Far

A recent entry comparing the German Carplane® and Burt Rutan’s BiPod has prompted a response from John Brown, who found the posting of concern for the misapprehensions it might cause in readers. He notes, for instance, “Your current article portrays us as a large Govt. Co. (we got a small subsidy) going up against a ‘charity’ organization (Northrop-Grumman’s subsidiary, Scaled Composites) in whose name the BiPod is registered at the FAA – as a glider; “It compares us to 1930s modular concepts where actually the BiPod’s wings are screw-on/screw-off ‘modular’ and use that older concept; “It attributes a commuter ‘pitch’ to us where, in fact, we’re not aiming for that market at all. [Thanks for your apology. However, the world …

A Swiss Swift

Dean Sigler Electric Powerplants, Feedback, Sustainable Aviation 0 Comments

Editor’s note: Livio Mengotti sent this comment regarding Dr. Steve Morris’s Swift’s first  flights in California, under the pilotage of Brian Porter.  (See “A Manned Swift Takes Flight,” March 1, 2010.) The videos are self-explanatory and filled with technical detail. Based on the videos, Switzerland is filled with open fields and glorious vistas awaiting aerial exploitation. Compare Livio’s undercarriage and pilot accommodations with those of Morris’s craft and the pod on Manfred Ruhmer’s Swift conversion.  Note, also, that the motor is mounted on the front of the wing, instead of behind it, as on the other two examples.  Congratulations for your performance! I built an electric Swift too. I made two flights on April 2010. I can mount and remove …

Synergy and Passion at EAS

Dean Sigler Electric Powerplants, Feedback, Sustainable Aviation 0 Comments

John Palmerlee, Editor of The Flying Wire, Experimental Aircraft Association Chapter 124’s newsletter, wote this in the May 5, 2010 edition.   The CAFE Team hosted what was in my opinion a very successful event at the Doubletree Hotel in Rohnert Park, April 23 and 24, 2010. Nearly thirty contributors from around the world spoke at the Electric Aircraft Symposium, and their message was clear: Change is coming… let’s get on board together. Electric airplanes and motorcycles, model airplanes, algae biofuel synthesis, wetlands initiatives, hybrid air carriers, battery breakthroughs, VTOL PAVs, tethered wind generators, flight systems analysis, nanostructures… and a mystery Green Flight Challenge aircraft promising to tap into new design paradigms. This was just a taste of the concepts …
