One of the biggest thrills this year at Oshkosh was getting to see Eagle Flight Research Center’s DA-36 run its YASA electric motor.  Eagle Flight, an outgrowth of Erik Lindbergh’s Powering Imagination program he’s been pursuing for the last several years, aims to create quiet electric aircraft that will carry sight-seers over National Parks and Monuments.  Such flights would not disturb people or wildlife below, and would give a Gabriel’s eye view of the most pristine places in our country. International Approval His ideas have met with international support.  As noted on the YouTube video of their meeting, “… Flavia Schlegel (Assistant Director-General (ADG) for the Natural Sciences) at UNESCO in Paris… gave an enthusiastic endorsement of our eSpirit of …

2017 Green Speed Cup – Airplanes More Frugal Than Priuses

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

The Green Speed Cup, held every year except for 2016 since 2011, is measure of an airplane’s efficiency, using a formula from the competition’s web site.  “The scoring will be very simple. The aircraft that flew with the best ratio of fuel-consumption per distance and speed will win the competition. The scoring of each competitor will be related to the winner. The winner gets 1000 points for one day.” According to Robert Adam, one of the organizers of the Cup, “We had a fantastic Green Speed Cup (and rightfully but reasonably prods your editor for not covering the results sooner.)  Luka Znidarsic from LZ Design won with his “front electric sustainer” Ventus glider. He had to close the gap between battery …

April 21 and 22, 2017, set your GPS for N 37° 31′ 20.84” W 122° 15′ 38.31” – the Hotel Pullman San Francisco Bay.  The refined and beautiful setting and four-star accommodations make a grand accompaniment to the story we will share. The story of the 2017 Sustainable Aviation Symposium includes the latest in aerodynamics, electric power and energy storage.  It’s a grand and sweeping review, told by talented intellects in the context of using the latest technology to help save the planet.  A few exemplars of the program highlight this year’s story, “ A Keynote Address from a Master Designer Tine Tomazic, Director of Research and Development for Pipistrel, created the G4 to win the 2011 Green Flight Challenge, …

EC04 Design Wins 2016 Berblinger Prize

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

A Big Win for Stuttgart Team Dipl-Ing Ingmar Geiß, Deputy Project Leader for e-Genius at the Institute of Aircraft Design at the University of Stuttgart, shared this pleasant news:  “I am happy to tell you that our hybrid-electric “ECO4” has won the Berblinger Prize 2016.  ECO4 combines an optimized electric airframe with a modern combustion engine generating electricity. This combination leads to an aircraft which cruises at 120 knots and consumes 40 percent less fuel than comparable state-of-the-art airplanes with conventional propulsion. As a further advantage, a small but powerful battery system enables a silent take-off without the combustion engine running, reducing significantly the noise emissions.”   The Berblinger Prize Gunter Czisch, mayor of Ulm, presented the 23,000 euro ($24,035 …

Pipistrel, Sino GA Sign Memorandum of Agreement

Dean Sigler Announcements, GFC, Hybrid Aircraft, Sustainable Aviation 0 Comments

China has over one billion, four hundred million people.  Slovenia has a little over two million.  This population disparity has not kept Pipistrel d.o.o. Ajdovscina and Chinese company Sino GA Group Co. from signing a Memorandum of Understanding for a long-term joint-venture in the field of light and general aviation in the regions of China, East Asian countries and the Asian Pacific region. Pipistrel, led by General Manager Ivo Boscarol, has built many airplanes in its 27-year history (including over 800 of its Sinus/Virus series), and earned plaudits for its clean manufacturing and ethical management.  It has led in development of electric motorgliders, an electric training aircraft, and a high-performance hybrid cruiser.  It won the Green Flight Challenge in 2011 …

HY4 Makes First Public Flight – Your Editor Rides EAA’s Ford Trimotor

A day after Pipistrel, the DLR and associates flew the first public demonstration of their four-seat hydrogen-powered HY4, your editor and a friend took a brief hop around the Aurora State Airport in Oregon in EAA’s Ford Trimotor, the first certified airliner in America.  The two events, roughly equal in duration, if not in historicity, demonstrate a readily observable progress in aeronautics. A quickening of design and technology 14 years after the Ford 5AT first flew on a scheduled route that took 51 hours total time to cross the United States (and split transport duties with trains), your editor’s father was whisked nonstop by Army Air Corps C-54 across the Atlantic to Shannon, Ireland, and then to Bobbington and Newquay, England …

e-Genius Flies with a Range Extender

Dean Sigler Batteries, GFC, Hybrid Aircraft, Sustainable Aviation 0 Comments

Stuttgart to Barcelona Dipl-Ing* Ingmar Geiß, Deputy Project Manager for e-Genius with the Institute of aeronautical engineering at Stuttgart University shared the news that e-Genius flew with its range extender for the first time on September 15.  He notes that while the battery-powered airplane can manage trips up to 300 kilometers (186 miles), the hybrid engine/generator pod will enable flights up to 1,000 kilometers (620 miles).  This would equal a trip from Stuttgart to Barcelona, Spain, according to the e-Genius web site. As the school explains, “With [the] e-Genius hybrid most flights of a typical user case can be done in the cost and energy efficient battery mode – for all longer flights the range extender can be used. Generator …

Speaking at the first annual Sustainable Aviation Symposium at the Sofitel San Francisco Bay on May 6, 2016.  Dr. Joseph Kallo focused on hydrogen as a more than potential fuel for future flight.  He stressed that H2 fuel development was further along than one would think, and shared several examples to promote that thought. A Busy Man, a Storied Airframe Dr. Kallo is DLR (Deutsches Zentrum für Luft-und Raumfahrt – German Center for Air and SpaceTravel) Coordinator of Electrical Aviation for Germany’s equivalent of NASA, oversees work at the DLR Institute of Engineering Thermodynamics, which has worked with Pipistrel in Slovenia to convert the Green Flight Prize winning Pipistrel G4 to the hydrogen-powered HY4. He’s also Institute Director at the …

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 …
