EV World reports that a Singapore-based company, Horizon Energy Systems, has test flown the world’s first hydrogen powered quadracopter, a small UAV that is claimed to fly for hours, instead of the minutes a lithium battery pack would provide. The report asks that tantalizing question for all who suffer from range anxiety, especially while in flight. “What if you could increase flying time by a factor of ten? Instead of half-an-hour, you could keep the UAV flying for five hours, and then charge it in a couple minutes time? That’s what Singapore-based Horizon Energy Systems is promising. They have developed micro fuel cells that can be fueled by three types of hydrogen storage systems from small compressed gas cylinders to ‘on-demand’ hydrogen generation chemical cartridges rated at 700 Watt-hours per kilogram (Whr/kg), significantly higher than the best lithium batteries.” Horizon’s Hycopter micro UAV quadracopter stores 120 grams (0.26 pounds) of hydrogen in its structure, equivalent to three kilograms (6.6 pounds) of lithium …
Good News and a Bright Future from EAS IX
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 …
Desert + Salt Water = Jet Fuel
Masdar, the United Arab Emirate’s clean energy development program, is hosting Solar Impulse as it prepares for its around-the-world flight. Beyond that, Masdar comprises five business units: Masdar Capital, Masdar Clean Energy, Special Projects, Masdar City and Free Zone, and Masdar Institute, “an independent, research-driven graduate university. Masdar Institute of Science and Technology is a multi-faceted research center, which although small at this time, seems to be fairly prodigious in the output of patents, patents pending and academic papers. The Institute heads a program to use “coastal seawater to raise fish and shrimp for food, whose nutrient-rich wastewater then fertilizes oil-rich halophyte plants that can be harvested for aviation biofuel production.” Halophytes, as those who’ve listened to or read Dennis Bushnell’s comments will know, thrive in harsh conditions including a diet of saltwater. Working with a consortium including Masdar, Etihad Airways, Boeing and Honeywell UOP, and later joined by aerospace companies Safran and GE, Masdar Institute’s initial laboratory-scale demonstrations could …
Boeing and Embraer Embrace on Biofuels
Brazil may become a central research and manufacturing site for biofuels, with Boeing and Embraer opening a joint sustainable biofuel research center, something that will rely on Brazil’s fertile land to supply non-food plants with which to make jet fuel. Working in the Boeing-Embraer Joint Research Center in the São José dos Campos Technology Park, opened in January 2014, the companies are continuing to “focus on technologies that address gaps in creating a sustainable aviation biofuel industry in Brazil, such as feedstock production, techno-economic analysis, economic viability studies and processing technologies.” Boeing’s Research & Technology-Brazil (BR&T-Brazil) Center, one of the company’s six international advanced research centers, leads the collaboration with Embraer and works with Brazil’s research-and-development community “to grow Brazil’s capabilities and meet the country’s goals for economic and technology development while supporting the creation of innovative and affordable technologies for Boeing’s business units.” This is one of several biofuel development projects in the U. S., the Middle East, Africa, …
Adam and Jamie are Paying Attention
Dr. Seeley alerted your editor this morning that Adam Savage and Jamie Hyneman’s web site, Tested.com, featured an entry on electric aircraft, “Fuel-Free Flight: the State of Electric Airplanes,” by Terry Dunn. Dunn does a good job of covering history and advantages of electric aircraft – complete with a quote from Dr. Seeley about the good neighbor aspect of quiet electric airplanes. He also discusses the barriers to electric aircraft development beyond current motor gliders and light aircraft – mainly the question of obtaining batteries that have much better energy densities than those currently available. “The batteries currently available are adequate to provide suitable range for some flyers. As the pool of available batteries improves, so will the range of electric aircraft and the number of pilots who embrace them. Despite continued progress, I think that a ground-breaking battery breakthrough is necessary before electric powered airplanes can become commonplace in the near term.” Despite the obstacles, he notes that the …
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 …
NTSB Releases Initial Report, Recommendations on Dreamliner Battery Fires
January 2013 was a time of great concern for operators of the Boeing 787 “Dreamliner.” On the 7th, an empty 787 operated by Japan Airlines experienced a fire in the main battery pack. On the 16th, an All Nippon Airways 787 made an emergency landing and evacuated everyone on board on emergency slides after the flight crew responded to a computer warning of smoke inside one of the electrical compartments. Other incidents pointed to issues in the use and transport of lithium-ion batteries such as those used in the big Boeing. The National Transportation Safety Board (NTSB) has directed several recommendations to the Federal Aviation Administration (FAA), derived from the agency’s ongoing investigation of the Japan Airlines incident only, at this time. Certainly the ongoing investigation of the All Nippon flight incident will merit a separate report. Despite the fact that many industry “insiders” have offered opinions as to how Boeing should have designed and constructed the two lithium-ion battery …
A Light Twin in the Business Community
Announced at Friedrichshafen’s Aero Expo and displayed (at least in model form) at the 2013 Paris Air Show, the Elektro E6 is the technology platform for a future, all electric transport aircraft. With low CO2 emissions, noise and vibration, the six-seat, two-motor airplane features full carbon composite structure. Solar cells on its high wing could help extend the range for this machine to 500 kilometers (310 miles), predicted if battery developments continue at their current pace for the next six years. The light twin would boast a payload of 480 kilograms (1,065 pounds). The E6 comes about as part of an Agreement of Cooperation between PC-Aero GmbH and EADCO GmbH. Rosario De Luca’s EADCO (European Aerospace Design Consultants), capable of supporting new designs from conceptual review through manufacturing has worked on projects for Boeing, Airbus, Fokker and Fairchild Dornier, along with Eurofighter. Calin Gologan’s PC-Aero has seen the inception and test flights of the Elektra One, Solar One and the creation …
Could This Be the Ford Bi-Motor?
The original Ford Tri-Motor had a body by Ford and three Pratt & Whitney radial engines arrayed across its nose and wings. The Phantom Eye has a body by Boeing, and two 2.3-liter Ford engines fueled by the hydrogen the airplane carries in its bulbous fuselage. It first flew last June, but hit a snag on landing, or at least dug in and twisted a landing skid, rendering it inoperable until this year. Boeing performed software and hardware upgrades, including strengthening the landing gear. Its second flight was a big success with a successful landing – a great one even, since the airplane is reuseable. This is particularly helpful for Boeing, which funded the project out of its own pocket. The company commented on the expectations raised by the flight: “Boeing’s liquid hydrogen-powered Phantom Eye unmanned airborne system completed its second flight Feb. 25, demonstrating capabilities that will allow it to perform intelligence, surveillance and reconnaissance (ISR) missions for up …
Fastest Electric Vehicle Design at EAS VI
Dr. Brien Seeley, President of the CAFE Foundation, has made the following announcement: “The Chief designer of the F-22 Raptor has prepared another spectacular design: The World’s Fastest Electric Vehicle. This new aircraft design will be presented along with the other outstanding talks at next week’s CAFE Electric Aircraft Symposium, April 27, 28 in Santa Rosa, California (Sonoma Wine Country). This symposium, dedicated to the burgeoning new domain of emission-free flight, now has representatives from Boeing, Bosch, IBM, Honda, Nortrhop-Grumman, Japan Air Lines, Rolls-Royce, Siemens, Aerovironment, FAA, Cummins, Cessna, Lycoming and many other companies enrolled to participate.” The high-speed electric may be a response to Ivo Boscarol’s pledge to put up $100,000 of his Pipistrel G-4 winnings at last year’s Green Flight Challenge for the first supersonic electric aircraft.
