EAS IX: JoeBen Pulls off a Hat Trick

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

JoeBen Bevirt, founder and head of Joby Aviation and Joby Motors , is obviously a workaholic, and not only gave a talk at EAS IX, but had an example of his Lotus unpiloted aerial vehicle at the AUVSI (Association for Unmanned Vehicle Systems International) conference in Atlanta, Georgia on the same weekend. Two weeks before that, his demonstration wing for the LEAPTech program was speeding across the desert at NASA’s Armstrong Flight Research Center (AFRC), Edwards Air Force Base in California. JoeBen told Symposium attendees all about his S2 personal aerial commuter and LEAPTech, a joint development with NASA. Part of the LEAPTech program has included building a truck platform for testing the 18-motor wing.  This is a fascinating bit of engineering …

EAS IX: Mike Ricci Explains PWB, Safety

Dreamliner battery nightmares have troubled the dreams of electric flight for the past two years.  Michael Ricci, Vice President of Engineering with LaunchPoint Technologies, gave attendees at this year’s Electric Aircraft Symposium a crash course (pun intended) in the many types of failure modes electric aircraft face.  Luckily, he also provided ways to mitigate and eliminate those failure modes. He introduced a concept called “Propulsion by Wire” (PBW), the main thrust for electric aircraft and roughly akin to the commonly discussed “Fly by Wire” concept.  Asking what product specifications for electric propulsion will look like, he answered his own rhetorical question with the technical requirements for reasonable interaction, a useful user interface, airworthiness, and safety. Starting with the last issue …

Powering Imagination in Seattle

Seattle’s Museum of Flight on Boeing Field will host a one-day event, Powering Imagination, an electric flight symposium organized by Erik Lindbergh, grandson of Charles and Anne Morrow Lindbergh. Presentations will be held in the William M. Allen Theater at the Museum, starting at 10:00 a.m. on Saturday, February 28 and ending at 5:00 p.m.   Admission is free, but RSVP to cwilcox@museumofflight.org to guarantee a seat. Topics include an update on the NASA LEAPTech aircraft being designed and built by Joby Aviation and powered by Joby motors.  This 20-motor (!) aircraft will achieve a high coefficient of lift from the motors that distribute thrust over the entire span. Eric Lindbergh will talk about the Quiet Flight Initiative, a multi-pronged approach to …
