The Lindbergh E-flight Rally coinciding with Friedrichshafen’s annual Aero Expo will explore the growing capabilities of these amazing machines.  The Lindbergh Foundation invites owners of electric aircraft to gather two days before the opening of Aero Expo 2020 to fly over the scenic marvels of Germany, alighting on Expo opening day “around 11 a.m., just on time for the AERO press conference.”   The hoped-for en masse arrival would highlight the number of electric aircraft now flying and their reliability.  Organizers explain, “Like the first ultralight aircraft did then, the first electric aircraft today need to prove that they already function perfectly.” The two-day aerial cortege would fly “along Lake Constance, and past castles, palaces, and churches, to a first stopover at Regio Airport Mengen, which was recently awarded a contract by the state of Baden-Württemberg for the construction of a test platform for electric flight/autonomous flying.”  There, entrants will charge their batteries and head for their second and last …

Doing More with Less – BLI on a Big Scale

Hybrid and electric cars sell because they lower operating costs for the owner.  Designers and manufacturers sort out ways to increase efficiency, including streamlining, using low-rolling-resistance tires, and making structures lighter.  An added technology, boundary layer ingestion (BLI) may add to aircraft efficiency. NASA and industry leaders are working on equivalent solutions for aircraft, and airplanes will end up as different from today’s designs as Toyota Priuses and BMW i3s are from Ford Falcons or Chevrolet Corvettes.  NASA proclaims, “An aviation renaissance, one focused on energy efficiency and economic impact, is on the horizon, and it’s changing how engineers look at aircraft power and design.” Jim Heidmann, a manager of NASA’s Advanced Air Transport Technology Project (AATT), says, “I feel we are at a tipping point in commercial aviation.  We are exploring and developing game-changing technologies and concepts for aircraft and propulsion systems that can dramatically improve efficiency and reduce environmental impact and accelerate the introduction of new aircraft.” Think of …

Good News and a Bright Future from EAS IX

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 1 Comment

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 progress in electric aviation, with future plans to develop two and four-seat aircraft for European and American markets from Airbus, and to produce a range of light-weight, commercially-available motors from Siemens. Siemens has 343,000 employees worldwide and revenues of 101.2 …
