We’re coming to a parting of the ways in energy storage development for electric cars. Or we may be coming to a joining of technologies in new and previously unimagined ways. One side, led by Elon Musk and his Tesla Empire, promotes battery power and development. Yet, in Tesla’s home state of California, government and private investments in hydrogen vehicles is growing. Several Asian and European automakers are bringing out fuel cell powered vehicles in the face of low numbers of existing fueling stations. For all the promotion from either side, future “green” cars may become too expensive for private ownership, and various approaches to providing personal mobility may replace the traditional owner-driver model. Regardless of the outcomes or market shares, the technology will be applicable to personal aviation, although perhaps at a significant price. Battery-Powered Vehicles Lead – For Now According to EV World, “In the last year, global registrations of electric vehicles from the first three years of …
EAS VIII: Dr. Jaiwon Shin Brings NASA to CAFE
The CAFE Foundation was honored this year to have Dr. Jaiwon Shin, Associate Director for the Aeronautics Research Mission Directorate. at the National Aeronautics and Space Administration (NASA), speak at the eighth annual Electric Aircraft Symposium. His responsibilities at the agency, and his earnest regard for CAFE and its direction were evident during his talk. According to his NASA biography, “Dr. Jaiwon Shin… manages the agency’s aeronautics research portfolio and guides its strategic direction. This portfolio includes research in the fundamental aeronautics of flight, aviation safety and the nation’s airspace system.” Such tasks include overseeing the next generation (NextGen) air traffic control system, funding promising research projects, crafting policies that will assure ongoing progress in creating cleaner, safer flight vehicles, and coordinating such activities with congress and other government agencies. He pointed out that the first “A” in NASA stands for “Aeronautics,” the agency’s first major area of research and policy making. Dr. Shin noted that the Wrights brought us powered, controlled …
Sunseeker Duo Goes Dual
Irena Raymond became the first passenger of a solar-powered airplane recently, even taking over control of the Sunseeker Duo she and husband Eric built over the last several years. Her thoughts provoke awe and envy. “Flying the Duo, skimming the white fluffy clouds from above and playing on the sky, I feel like a bird. No limitations, a pure freedom. It’s so quiet! Compared to a normal airplane, it’s like night and day. You need a very good headset in every other powered airplane, but in this airplane you can speak normally even when the motor is running full power, no headset needed. It is unbelievable.” Eric provides some hard data to complement Irena’s understandably poetic words. “I am expanding the flight envelope, so far up to 13,000 feet and 85 mph. My heaviest passenger… is 85 kilograms (187 pounds), and we were able to climb up to 12,500 feet. 80 percent of the solar cells are hooked up.” Responding to …
Dr. Shin to Keynote Electric Aircraft Symposium
Dr. Jaiwon Shin, NASA Associate Administrator for Aeronautics, will close the Friday, April 25 session of the eighth annual Electric Aircraft Symposium with his keynote address, “The NASA Aeronautics Vision and Strategy – How It Relates to Electric Aircraft.” As Associate Administrator, Dr. Shin “manages the agency’s aeronautics research portfolio and guides its strategic direction,” according to his official NASA biography. He co-chairs the National Science & Technology Council’s Aeronautics Science & Technology Subcommittee, a group of federal departments and agencies that fund aeronautics-related research. Its first presidential policy for aeronautics research and development (R&D) was ratified by Executive Order 13419 in December 2006, and now guides such research until 2020. Dr. Shin oversees and sets policies for an array of explorations into aerodynamics, propulsion, air traffic control – including NextGen, aviation safety, and the integration of such technologies into broader economic and strategic concerns at the national and international levels. With myriad Aeronautics Research Mission Directorates (ARMD) and at …
Green Speed Cup Day Two – A Clear Winner
Robert Adam, one of the organizers of the Green Speed Cup in Germany and pilot of the Flight Design CTLS that ended the competition in seventh place, shared some information on the challenges faced by pilots in this year’s event. “We had 12-15 knots crosswind today (only a little less yesterday) and Tim-Peter (-Voss) managed this demanding taildragger (the SPACEK s.r.o. SD-1 microlight) calmly!” This very light and short-coupled airplane flies with a variety of two- and four-stroke engines, but Voss’ had a Verner JVC-360 four-stroke unit of 38 horsepower. It averaged a little over four liters per hour fuel consumption per 100 kilometers (59 mpg) over the practice day and two contest days. In the Green Flight Challenge, it would have been penalized for being a single-seater and thus having a lower passenger-mile-per-gallon figure than the two, and even four-seat entrants. The TDI turbo-diesel DA-40, for instance, would have had a 4X passenger mile per gallon figure if that had …
Green Speed Cup – Training Day is Over and Day One Establishes a Record
Happily for those of us who champion the idea of electric aircraft, the practice day and day one of the Green Speed Cup in Strausberg, Germany fetched a world electric aircraft distance record for e-Genius and an outstanding showing for all concerned. This beginning for the third running of the Cup sets a high standard for the coming days. The Green Speed Cup has elements of soaring flight through the use of thermals, careful speed flying that emphasizes fuel economy, and precise flight planning with attention to the planned route, winds aloft, and power settings. Green Speed Cup organizers map out a series of triangular routes to test the limits of piloting skills and airplane efficiency. As the organizers explain, it’s all pretty simple: “To fly ‘green’ you have to know how fast to fly and which power setting to use. This depends on the current wind-profile, on the current lift and on several other parameters like the aerodynamical properties.” …
Aviation Week Recognizes CAFE Foundation’s Efforts
As noted in this blog. Dr. Brien Seeley, President of the CAFE Foundation, has been actively promoting the idea of a short to intermediate range Sky Taxi, a two-seat aerial vehicle that would carry its passengers safely from 420-foot runway “pocket airports” to other such runways at other urban and suburban settings, or even pockets situated within major airports. The safety and utility promised by these electrically-powered aircraft would provide convenient, inexpensive trips for commuters who would enjoy TSA-free travel up to 500 miles at point-to-point speeds exceeding even private LearJets. Aviation Week recently noted efforts by John Langford, CEO of UAV specialist Aurora Flight Sciences, to achieve part of Dr. Seeley’s far-reaching goals with today’s technology. As Graham Warwick reports in the magazine, “Five years after DayJet’s on-demand air service using very light jets ceased operations, the dream of air taxis remains alive. But industry is looking at unmanned aircraft technology as a way to reduce or eliminate the …
Dr. Seeley Speaks at AIAA Conference, NASA Dryden
Dr. Brien Seeley, Founder and President of the CAFE Foundation, has been giving a series of talks at the Experimental Aircraft Association’s AirVenture 2013, before a gathering of technical experts at NASA’s Dryden Flight Test Center, Edwards Air Force and at the American Institute of Aeronautics and Astronautics (AIAA) International Powered Lift Conference in Los Angeles. The International Powered Lift Conference focuses on the latest developments in Vertical or Short Takeoff and Landing (V/STOL) aircraft research, concepts, and programs, something of great interest to CAFE in its development of airplanes capable of using pocket airports. Pocket Airports will require a special type of airplane – electric, according to Dr. Seeley, and capable of taking off with a ground roll of 90 feet (home plate to first base), able to climb at an angle that would clear the 150-foot Matterhorn at Disneyland by the time it reaches the end of a 420-foot runway, and being nearly inaudible as it crosses the …
NASA, CAFE Aims and Goals Converge
Charles F. Bolden, Jr., a retired U. S. Marine Corps Major General, astronaut and now NASA Administrator, had enough adventures in any one of his careers to have made several who’s who lists. The twelfth administrator of the National Aeronautics and Space Administration, his previous careers included 34-years in the Marine Corps during which he spent 14 years as a member of NASA’s Astronaut Office, traveled to orbit four times on the space shuttle, deployed the Hubble Space Telescope, and flew on the first U. S.-Russian joint shuttle mission. As a Marine fighter pilot, he flew over 100 combat missions during the Vietnam conflict; and during the first half of 1998, served as Commanding General of the 1st Marine Expeditionary Force Forward in support of Operation Desert Thunder in Kuwait. According to his NASA biography, “Bolden’s many military decorations include the Defense Superior Service Medal and the Distinguished Flying Cross. He was inducted into the U.S. Astronaut Hall of Fame …
Dr. Seeley at AirVenture 2013
Imagine being able to walk one morning from your front door to a nearby small airport, step into an electrically-powered small airplane, point to a destination on an illuminated map on the airplane’s display screen, and be whisked to your destination so quietly that your passage overhead will not wake your neighbors. This is part of the dream that Dr. Brien Seeley, founder and President of the CAFE Foundation, presented to an appreciable and appreciative crowd on Friday, August 2 at the Rotax Pavilion during the Experimental Aircraft Association’s AirVenture 2013. His talk, “The CAFE Foundation’s Green Flight Challenge Program: Toward a New Transportation Mode,” was a roadmap to how the CAFE Foundation, NASA and corporate sponsors will present five new challenges leading to the type of electric short or vertical-takeoff and landing airplane that will enable neighborhood pocket airports. He also challenged EAA members to become involved, using their technical knowledge and talents to further the development of quiet, …
