Tecnam Goes Electric in Parallel and with Batteries

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

Tecnam, an Italian aircraft producer noteworthy for supplying the base aircraft for NASA’s X-57 Maxwell distributed electric test vehicle, has two of its own electric craft under development.  One will be a parallel-hybrid single-engine/motor four-seater with perhaps the smallest motor Rolls-Royce can supply.  The other will employ a battery-only system to power an 11-seat commuter aircraft. Tecnam’s history, starting in 1948, includes the design and manufacture of over 33 types of aircraft, with deliveries of over 5,500 airframes in more than 65 countries. Parallel Power Introduced in 2018, the H3PS (“High Power High Scalability Aircraft Hybrid Powertrain”) project was a collaboration among Tecnam, BRP-Rotax and (at the time) Siemens, which supplied the electric motor.  Siemens’ electric aircraft division has since …

DLR’s Novel Configurations

Researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) conducting research into the potential of new types of design have crafted novel configurations for future flight.  The DRL and BDLI (German Aerospace Industries Association or Bundesverband der Deutschen Luft- und Raumfahrtindustrie)  have published a white paper: “Zero Emission Aviation – Emissionsfreies Fliegen” explicating these configurations. Surprisingly, one of their major findings is that “Electric flight enables lighter aircraft with smaller wings and distributed propulsion systems.”  Battery weight has caused MagniX and Ampaire to reduce the number of passengers or the cargo loads on conversions of existing airframes.  To counter those issues, “An EU research project is investigating the potential for new propulsion systems and aircraft concepts.”  …

APUS Introduces Two Zero Emission Craft

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 …

UAM Realization May be Closer than We Think

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

Dean Sigler Electric Powerplants, Hybrid Aircraft, Sky Taxis, Sustainable Aviation Leave a Comment

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 …

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 …
