Verdego Aero – Another Variant on VTOL Travel

Dean Sigler Electric Powerplants, GFC, Hybrid Aircraft, Sustainable Aviation 0 Comments

A Controversy for Starters Skeptics abound concerning the current spate of vertical takeoff and landing (VTOL) machines.  The latest entry in the competition comes from the trio of Erik Lindbergh, Eric Bartsch, and Pat Anderson of Embry-Riddle Aeronautical University.  Their Verdego eight-rotor machine looks a bit like the Airbus A3 Vahana, but has pusher, rather than puller, propellers on the rear wing. On his Linked In page, Bartsch jumps into an ongoing fray with his article, “The Inevitability of Short-Range Urban Aviation – Why I’m Betting Against the “Flying Uber” Skeptics.” It takes aim at the opposing point of view in “Going Direct: On the Insanity of Flying Ubers,” by Plane & Pilot writer Robert Goyer.  To shorten the two …

Dean Sigler Batteries, GFC, Sustainable Aviation 0 Comments

On August 30. Pipistrel inaugurated the first electric charging station to fully warrant the name, charging one of their own Alpha Electro trainers.  The project was co-financed by the Ministry of Education, Science and Sport and the European Union from the European Social Fund.  Led by Pipistrel, the LECAD Laboratory, and the Academy of Fine Arts and Design, mentors and students developed and constructed a fully-functioning station. Technical characteristics of the charging station:  – capable of charging two electric aircraft at the same time – current strength: 2 x 20 kW – charge speed: one hour to fully charge Alpha Electro – operating voltage 3f 400V AC – WiFi connection to the network As Pipistrel explains, “The goal of the …

Madagascar Medicine Meets the Green Flight Challenge

In the Small World category, the team leader of the 2011 Green Flight Challenge winning team is designing the next generation of a drone that can carry blood and stool samples from remote and otherwise inaccessible parts of Madagascar to a central laboratory where the samples can be analyzed.  Jack Langelaan, Professor of Aerospace Engineering at Pennsylvania State University, is working with Vayu Aircraft to develop a vertical takeoff and landing machine specially crafted to meet the needs of the ValBio Centre. The video shows an early version of the drone, while pictures on Vayu’s web site depict a sleeker, more refined approach.  The functionality for both machines would seem to be identical, but the styling for the projected future …

e-Genius Crosses the Alps on Battery Power – Twice!

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 2 Comments

It makes your editor’s morning to receive such wonderful emails.  Dipl. Ing. Ingmar Geiß, Deputy Project Manager for Overall Aircraft Systems on e-Genius wrote the following: “We had a great Saturday – we flew from Stuttgart over the Alps to Italy, recharged the batteries and flew back on the same day!  For us, this shows the practicability of battery powered aircraft and we think this is a milestone towards an eco-friendly and efficient aviation.” The e-Genius web page on the University of Stuttgart site expands on the story, describing the flight’s accomplishment. “A milestone towards an energy efficient and carbon-neutral aviation has been reached.” While Americans rested up for their Fourth of July festivities, “Saturday morning, the electric aircraft “e-Genius” …

Green Speed Cup Final: a Mix of Well-Flown Aircraft

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

Day three of the Green Speed Cup in Strausberg, Germany brought few surprises other than how fuel efficient all of the aircraft turned out to be, especially considering they are all powered by gasoline engines.  Normally, this would demonstrate that even a light machine uses large amounts of fuel, but this contest demonstrated the benefits of good design and careful piloting. The Akaflieg Darmstadt D39 flown by Holger Massow came in first, winning the last two days outright.  Second went to Hans-Peter Ortwein flying a Stemme SV-10T, and third, perhaps surprisingly, to the only two-stroke powered machine, a Technoflug Piccolo, a fixed-gear, high-wing motorglider with an engine sticking up behind the wing.  The Piccolo was flown by Werner Scholz. Two …

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 …

Carplane Makes a Comeback

Dean Sigler GFC, Sustainable Aviation 1 Comment

The German firm Carplane made an entry into the media a few years ago, especially when it compared its bi-modal flying car with a Burt Rutan design.  That started a brief kerfuffle of edgy comparisons between the two groups, but no necessary winner.  Now, having shown at least a finished and apparently drivable vehicle at Aero 2015, Carplane has renewed prominence in the media.  And the blog brings it all back, prepared for less-than-flattering comments. Stating what may stir others to contend for their rival mounts, Carplane makes a bold claim.  (The italicized and bolded word is Carplane’s emphasis.) “Flying cars will soon be a reality. And Carplane® is the world’s only flying car currently undergoing formal certification. Watch this page as we …

e-Genius Extends Its Range

Dean Sigler Diesel Powerplants, Electric Powerplants, GFC 1 Comment

Shown at the E-Flight Expo at Friedrichshafen’s Aero 2015, Stuttgart University’s e-Genius had an aerodynamic-looking pod next to one wing, containing an ENGIRO range extender consisting of a Wankel-type engine and a generator.  The unit could, as its name implies, help e-Genius go for new records to add to its already significant collection. Bill Lofton at EV Hangar has detailed the extender, now associated with the e-Genius and in a larger variant on the Equator P2 amphibian being built in Norway by Tomas Broedreskift. Equator’s web site describes its power system: “The hybrid propulsion system being developed by Equator is called EHPS (Equator Hybrid Propulsion System). The engine specific project is being co-funded by Transnova and the company doing the development work …

Powering Imagination at the Museum of Flight

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

Powering Imagination, a symposium devoted to that premise and to encouraging the development of electric aviation, achieved both goals on Saturday, February 28 at Seattle’s Museum of Flight.  Organized by Erik Lindbergh and Eric Bartsch, the gathering included two panel discussions and eight presentations that helped define where the world of electric flight might be heading.  Between 10:00 a.m. and 5:00 p.m., presenters covered a lot of ground. Following Cale Wilcox, the Public Programs Coordinator for the Museum’s, introduction, Erik Lindbergh took the stage to explain the goals of the Powering Imagination organization, including making aviation clean, quiet, exciting and affordable.  This democratization of flight mirrors aspirations of the CAFE Foundation and is reflected in the educational efforts made by …

A Cheerfully Acknowledged Chastisement

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

If one writes things, occasional slip-ups creep in.  In this case, an unchallenged assertion of who is “first” drew this kind email from Klaus Savier, builder, tuner and pilot of a very slippery Long-Eze.  He’s flown from California to Florida and back on good old fossil fuels (with one fuel stop each way) in his highly modified Long-Eze and achieved 30 miles per gallon at 250 miles per hour true airspeed.  It would be interesting to see how little fuel the airplane would consume at Green Flight Challenge airspeeds.  His demonstrated 0.36 pounds of fuel per horsepower-hour is claimed by Klaus to be 40-percent lower than the commonly seen 0.60 pounds per horsepower-hour that engines without his Light Speed Engineering …
