We’ve written several times about structural batteries in this blog, from Dr. Emile Greenhalgh’s early research at Imperial College to more recent efforts along the same line.  Interestingly, the basic idea remains very much the same over a decade.  Energy storage would take place in a monocoque-type structure that could use carbon fiber, fiberglass, and even graphene as  a structural material, while acting as a battery.  Now some of this thinking is being applied to hydrogen storage in wings. “TubeStruct™” APUS, an aircraft design, structure and certification operation in Strausberg, Germany, offering a full range of services including flight training.  They recently announced two new craft, both featuring hydrogen fuel systems contained in a novel “…  patented structurally integrated hydrogen …

We are on the verge of big happenings in the Urban Air Mobility (UAM) world.  Large amounts of money are flowing into the coffers of those companies which dared to pioneer in the area.  Large firms are partnering with these aerial startups.  And the Federal Aeronautics Administration is paying attention while actively pursuing certification for the new machines headed our way. Jay Merkle, FAA Certification and Airspace Integration At the Transportation Review Board’s annual meeting in Orlando, Florida, Jay Merkle, head of the FAA’s UAS integration office, told attendees that six (Urban Air Mobility) UAM  vehicles are “well along,” according to a report in Aviation Today.   He held that the growing market is ““more than just hype … this is …

ACCELL: A (Mostly) British Coalition Going for 300 MPH

Dean Sigler Batteries, Electric Powerplants, Sustainable Aviation Leave a Comment

Rolls-Royce is perhaps the epitome of Britishness, going back to 1904, when Henry Royce, founder of a successful mechanical/electrical business, met Charles Rolls, a successful car dealer in London.  Together, the founded the company which came to be known as Rolls-Royce.  By 1906, their Silver Ghost was known as “the best car in the world.”  That quality was inherent in their first aircraft engine, the Eagle, “providing some half of the total horsepower used in the air war by the allies.”  It provided the power in 1919 for the first direct flight across the Atlantic and the first flight from England to Australia – both in Vickers Vimy aircraft.  This led to racing success, with early V-12 engines by R-R …

Rolls-Royce ACCEL Program Goes For the Gold

Dean Sigler Batteries, Electric Powerplants, Sustainable Aviation Leave a Comment

Rolls-Royce’s ACCEL program and a consortium of partners want to create the world’s fastest electric airplane.  The concept has a recent series of predecessors, and a fascinating tie to an American speed champion. About five years ago, something called the TEACO (The Electric Aircraft Company) Bat, a formula 1-type raceplane powered by an electric motor, generated a great deal of interest.  It initially housed a single 80-horsepower electric motor, but once affiliated with Williams Engineering; the project added a twin-motor unit on a set of sleeved parallel shafts swinging contra-rotating propellers. Now, a partnership led by Rolls-Royce seems to have added a third motor, with all three singing in unison to drive a three-bladed propeller.  The airframe is new, too, …

Rolls-Royce Rolls a Few New Approaches

Rolls-Royce, famous for building engines such as the WWII Merlin that powered Spitfires, Mustangs, Mosquitos and Lancaster bombers, is engaged on three (or four) fronts currently, bringing hybrid electric transport to the skies. Hybrid Electric VTOL for Commuting Rolls is jumping into this crowded market segment with its concept for an electric VTOL (Vertical Takeoff and Landing) machine, powered by four electric motors on the wings and two on the tail.   With over 100 machines of varying configurations that might be the Uber rides of the future – according to Electric VTOL News, Rolls, normally a conservative company, is planning something a bit radical – even in this field. Rolls’ headline for this craft indicates a new direction for the …

Rolls-Royce, Airbus and Siemens Team Up on Hybrid Airliner

As many of your editor’s friends know, he is often lured to trolling the tabloids, looking for juicy bits about the royal family or Hollywood royalty.  Recently, while perusing the Daily Mail* for news of the upcoming Harry/Meaghan nuptials, he came across the big-headline news that three European power players – Rolls-Royce, Airbus, and Siemens, are collaborating on creating a testbed for a hybrid power system. The trio will take a Bae 146 four-engine regional jet, convert it to a hybrid demonstrator by 2020, and have a production plane in place by 2030.  The high-wing airplane has four turbofans in place now, but the partners will replace one with a Siemens two-megawatt electric motor powered by a Rolls-Royce two-megawatt generator …

Boeing and Embraer Embrace on Biofuels

Dean Sigler Diesel Powerplants, Sustainable Aviation Leave a Comment

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 …

EADS’ Electrifying Threesome at Paris Air Show

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

EADS (European Aerospace Defense Systems), known colloquially as Airbus, highlighted its Paris Air Show chalet at Le Bourget with three  examples of the work from its Innovations Workshops. All projects are part of the European Commission’s “Flightpath 2050” initiative, conceived to reduce carbon dioxide (CO2) emissions 75 percent, nitrogen oxide (NOx) emissions 90 percent and noise  65 percent from 2000 levels by 2050. EADS thinks electric and hybrid propulsion could become an alternative to fossil fuels within that timeline, with several projects highlighting, “the willingness of EADS to invest in technologies that today, tomorrow, will further reduce emissions of carbon dioxide from aviation.” E-FAN Working with Aero Composites Saintonge (ACS), the IW Research and Technology Group has developed and built the …

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 …

Charging Your EV on the Move

Qualcomm is best known for its quirkily-named Wi-Fi and other wireless communications technologies; ETHOS®, Haystack®, and Gobi®, for starters.  Relatively low-powered, they allow notebooks and smartphones access to broadband connectedness. Qualcomm has now expanded its reach, and its power, to inductive charging for electric vehicles.  Its wireless electric vehicle charging (WEVC) technology, HaloIPT will first allow wireless recharging of electric vehicles which park over a “sweet spot” that has the capability of sending power “over an air gap of hundreds of millimeters while still maintaining high-energy transfer electricity,” according to the company. PCWorld reports that Halo’s inductive “WEVC can transfer up to 3.5 kilowatts of power at greater than 90 percent efficiency – that’s as good as, or even better, …
