Dean Sigler Batteries, Electric Aircraft Components, Electric Aircraft Materials, Electric Powerplants, Sustainable Aviation 0 Comments

Aviation Week reports from the Paris Air Show on a “disruptive” entry in electric aviation.  Eviation, founded by Omer Bar Yohai, is primed to deliver a change in transportation as we know it.  Yohai says, “The dominant solutions available today are deeply flawed and demand disruption.” The company’s promotional video only hints at the company’s intentions.  Their vision statement on their web site, though, indicates a skyward aspiration: “Making electric aviation the fast, competitive and clean answer to on-demand mobility of people and goods.”  Aviation Week’s Noam Eshel quotes Bar Yohai as saying, “We design, test and build the tools that will enable future of regional transit by air, changing consumers’ perception of both distance and time.  Five years from …

Look Up and Say Cheese!  Autonomous Mapping from the Elektra One Solar

Dean Sigler Electric Aircraft Components, Solar Power, Sustainable Aviation 0 Comments

Had the residents of Landshut, a 13th-century city in Lower Bavaria, chanced to look up at the right time over the last few weeks, they might have glimpsed a bright yellow shape looking back at them.  Calin Gologan’s latest Elektra One Solar carries a suite of cameras that can transmit 2D movies in 4K resolution to a ground station up to 40 kilometers (25 miles) away.  Through sophisticated software, the images can be translated into 3D maps with a resolution of five centimeters (just under two inches), the primary mission of the flights. Partner ViaLight, a 2009 spin-off of the DLR (the German Aerospace Center), provided the hardware and software that allows up to 100 Gbps (gigabits per second) data …

Not a Goldschmied Fuselage, but Still Wonderfully Low Drag

Dean Sigler Electric Aircraft Components, Electric Powerplants, Sustainable Aviation 0 Comments

Following your editor’s blog entry on the Prandtl wing and erroneously named Goldschmied fuselage, he received this correction from Dr. Brien Seeley, President of the Sustainable Aviation Foundation and one of the creators of the body in question. “However, it is, I think, important to note:  We did not fabricate a Goldschmied body and it is incorrect to refer to ours as one. Ours is original, unique and it does not at all rely upon Goldschmied’s annual suction approach (aft boundary layer treatment). A Goldschmied body studied at Cal Poly is shown along with a link to its 205 page study.  It differs by having a pointed nose and sharp convergence at the rear annular inlet to create the concave …

An Image of the Future at the 2017 Sustainable Aviation Symposium

Dean Sigler Electric Aircraft Components, Sustainable Aviation 0 Comments

The Seeleys and SA board members did themselves proud for this year’s Sustainable Aviation Symposium.  Your editor visited the grand ballroom in the San Francisco Bay Pullman Hotel the night before the meeting was to take place.  All the tables, chairs and stage were in place, but the room was otherwise bare.  Early next morning, your editor trudged downstairs again, to be met with an astonishing sight.  At the back of the ballroom, a pair of exotic geometric shapes glowed in blue and green lighting.  Somehow, a 50-foot wing and substantial streamlined shape had materialized overnight.  Already, attendees were peering up at the extremely twisted tips of the wings and trying to analyze what they saw before them. Aspirational Geometries …

Aero, an annual event at Friedrichshafen, Germany, highlights the beginning of the European air show season.  E-Flight Expo has been a regular part of this for the last several years, and displays the latest in electric flight technology.  Certainly the most forward-looking part of the show, the Expo grows every year.  Several exhibitors helped further the advanced look this year. MGM Compro With at least five aircraft powered by their electric power systems on display, MGM Compro showed great market strength.  The Czech firm has 16 of its motors atop each Volocopter 200, with one as a propulsor in the tail.  Their motors power the Magnus e-Fusion aerobatic trainer, several GP gliders, the S.R.O. Song motorglider, and any number of …

Airbus E-Fans 2.0 and 4.0 Dropped in Favor of E-Fan X

Dean Sigler Electric Aircraft Components, Hybrid Aircraft, Sustainable Aviation 0 Comments

Much like waiting for the single-person ram-jet helicopter to show up in your garage, you’ll be left hanging for a two- or four-seat Airbus e-Fan to grace your hangar.  Although not sharing the news in its “Innovation” or press release sections on its web site, Airbus has announced that it’s dropping plans to produce an E-Fan family of personal aircraft.  It will move instead into developing a larger, more powerful aircraft, the E-Fan X, that could fly within three years. Airbus started with a four-motor rendition of the Cri-Cri, four MGM Compro units twirling contra-rotating propellers and producing 60 horsepower.  Their “Innovation” program followed that with the tw0-seat E-Fan, and announced plans to build these in series at their cleverly named …

 George Bye – Electric Aerospace in Small, Medium and Large

Dean Sigler Electric Aircraft Components, Hybrid Aircraft, Solar Power, Sustainable Aviation 0 Comments

George Bye has been crafting and testing electric aircraft for the last decade and now has four craft of varying size demonstrating the reach of his vision.  Bill Moore interviewed George for EVWorld.com recently.  We’ll review the airplanes with which George is involved, starting small and working up to a spectacular cross-country cruiser. Silent Falcon Although the UAV company associated with the Silent Falcon is not part of Bye Aerospace, it had its origins there.  Now located in Albuquerque, New Mexico, Silent Falcon operations are overseen by John Brown, former Chief Financial Officer (CFO) for Bye Energy. Silent Falcon’s glider-like 14-foot wing, high efficiency airfoil, electric power and high-efficiency solar cells allow up to five-hour surveillance flights.  Its ability to …

TAG – You’re Down!

Dean Sigler Electric Aircraft Components, Electric Powerplants, Sustainable Aviation 0 Comments

Nailing the landing is a big test for gymnasts, birds, and in the near future – for electric commuter aircraft.  Landing in an impossibly short distance seemed like a mission only for helicopters until recently.  Fixed-wing machines seem at a disadvantage here, rotary-wing craft having the edge in being able to set down almost anywhere, and on the proverbial dime.  Brien Seeley’s TAG may make it possible for fixed-wing craft to emulate birds. Fixed-wing craft have the advantage in point-to-point speed – a big selling point for commuter craft.  High cruising speeds and short ground runs seem mutually exclusive, although new designs and inspired amateurs are showing the way to combining the best of both worlds. First, it’s apparent from …

Pop.Up – Airbus Pops Up with Another VTOL Commuter

Dean Sigler Batteries, Electric Aircraft Components, Electric Powerplants, Hybrid Aircraft, Sustainable Aviation 0 Comments

What will Pop.Up next?  We’re floating away, being carried skyward by PAL-V’s, JetPack’s 12-rotor machine, e-volo’s 16-rotor design, and even Hoversurf’s four-rotor flying donor-cycle. At least a half-dozen other varieties of VTOL (vertical takeoff and landing) commuter machines are coming at us with bewildering speed.  If nothing else, the competing visions of future aerial transport show some kind of deeply felt need to escape the surly bonds of earth, or at least its eternal gridlock. Airbus has already played one hand, showing its cards with Silicon Valley-based A3 (A Cubed) and a vehicle looking like a combination of NASA’s X-57 Maxwell and Joby Aviation’s S2.  It pulled another card from its sleeve this week at the Geneva Auto Show, unveiling …

Hoversurf – The Russians are coming with Flying Bikes

Dean Sigler Electric Aircraft Components, Electric Powerplants, Sustainable Aviation 0 Comments

Hoversurf, a Russian flying motorcycle, has been getting a lot of press lately.  “Looks like a hell of a ride,” trumpets TheNextWeb.  Mashable headlines, “The first manned hoverbike could finally fulfill your ‘Star Wars’ dreams,” but points out, “Those dangerous-looking propellers spinning right next to the pilot’s legs.” New Atlas (formerly Gizmag) says it is, “Equally amazing and horrifying.” https://www.youtube.com/watch?v=ztr5eyASasQ Hoversurf’s Scorpion evokes Star Wars with its clean white gloss.  But like the movie’s speeder bikes flung about by heroes and villains alike, seems equally dangerous with its wooden propellers at two different heights – ankle-biter and knee-slapper.  Protective shields theoretically will prevent slicing and dicing, and future plans call for an enclosed cabin with the occupant more secure from …
