When You Wake Up Hungry – Fly to the Bakery!

Electric-Flight.eu reports on three Germans who made a bathtub fly – and used it to fetch pastries.  As the website reports, “The Real Life Guys” are two Darmstadt students and one DB train attendant who shook up the media last week . They connected a bathtub with an aluminum scaffolding and six 9.6 [kilowatt] motors (€1 065 or about $1,191[each]) from the model building sector to 42-Volt batteries and blew it up.”  “Blew it up” means lifting it skyward on the power of what look like six Hacker model airplane motors, capable of putting out 15 kilowatts (20.1 hp) each for 15 seconds.  The 9.6 kW (12.9 hp) output cited in the Electric-Flight article seems realistic for sustained output, and …

AirSpaceX is NOT an Elon Musk Company

Dean Sigler Electric Powerplants, Sky Taxis, Sustainable Aviation 0 Comments

Airspace Experience Technologies, LLC (AirSpaceX) is a subsidiary of Detroit Aircraft Corporation (DAC), and as far as this editor knows, not related to Elon Musk’s SpaceX.  A little closer to earth, the planned low-altitude perambulations of its two creations reflect the growing interest in “sky taxis.” A Holding Company Brought Down by the Great Depression Jon Rimanelli, founder and CEO, sees Detroit Aircraft Corporation as an attempt to return the Motor City to its former glory days as a leader in aircraft development.  He notes that for a few brief years, DAC held controlling interests in the Ryan and Lockheed Aircraft companies, and created the only metal-clad airship in aeronautical history, The ZMC-2.  He explains, “Back in the ’20s, Detroit …

CES 2018 – Intel Inside and Then Some

Dean Sigler Electric Powerplants, Sky Taxis, Sustainable Aviation 0 Comments

Brian Krzanich, Intel’s CEO, took a ride in the Volocopter 2X, becoming the first human passenger on an autonomous flight of the vehicle.  The ride took place in a large enclosed space somewhere in Munich, Germany, on December 3, 2017. An Historical Sidebar It looks a little like Hanna Reitsch’s helicopter flight under the roof of the Deutschlandhalle in Berlin in 1938, a feat she repeated daily during the three-week International Automobile Exhibition.  She later test flew an early V-1 “Buzz Bomb,” her small size adaptable to the craft.  Volocopter’s 2X requires far fewer flying skills, CEO Florian Reuter claiming a five-year-old can control the 2X. Not a Flying Car Sean O’Kane, enthusiastically reporting on the 2X for The Verge, …

Book Your Perth Alpha Electro Flights for the Early Morning

Dean Sigler Electric Aircraft Components, Electric Powerplants, Sustainable Aviation 0 Comments

Two Things That May Not Seem Related at First Recent news that Penrith, Australia was the hottest place on earth was underlined by videos of melting highways.  Penrith, a suburb of Sydney, reached 47.3° C (117° F), enough to turn asphalt into a sticky mess and force drivers onto less gummy shoulders. Although over 2,400 miles away, Perth, home to Joshua Portlock’s Electro.Aero flying service, is at roughly the same latitude, and experienced near-record heat this month.  Possibly, that accounts for the all-caps caution for prospective flyers: “WE RECOMMEND EARLY MORNING FLIGHTS IN SUMMER FOR THE SMOOTHEST CONDITIONS.” Joshua’s company took delivery of a Pipistrel Alpha Electro, and flew it on January 2, a first in Australian aviation.  He and …

China Updates, Increases Range for RX1E-A

Dean Sigler Batteries, Electric Powerplants, Sustainable Aviation 1 Comment

China Global Television Network, or CGTN, reports on an updated version of an electric airplane that first took flight in 2015.  The original RX1E could fly for 45 minutes on its battery pack, limiting its utility.  The RX1E-A’s six lithium battery packs can keep the new machine in the air for up to two hours and achieve a maximum speed of 160 kilometers per hour (99.4 mph).  This type of performance makes it more suitable for training and cross-country flights. Similar to a long-winged version of Pipistrel’s Alpha Electro Trainer, soon to be produced in China, the RX1E-A grosses out at 600 kilograms (1,320 pounds), suitable for most Light Sport Aircraft regulations.  It will be interesting to see if production …

Too Late for Boxing Day*, Ehang Delivers the Goods

Dean Sigler Batteries, Electric Powerplants, Sky Taxis, Sustainable Aviation 0 Comments

Broadcast live on December 24, this demonstration of the eHang 184 is, interestingly, an English-language presentation, with a lot of English names floating about. Someone named Mike shows off the Ehang 184 in this Christmas-related special.  His friend Miranda snugs herself into the compact passenger compartment, tries on the safety harnesses, and deplanes before committing aviation.  The video is a sales pitch for the drone manufacturer – actually more of a long wind-up before a pitch into the air.  Mike takes us through a tutorial on the craft, which seats one passenger and has eight propellers that are mounted on four arms (one-eight-four, or 184). The rather ungainly entrance and exit of the petite young woman suggests possible improvements eHang’s designers …

Toyota, BMW Fahrting Around with Clean Energy

Dean Sigler Biofuels, Electric Powerplants, Fuel Cells, Hydrogen Fuel, Solar Power, Sustainable Aviation 0 Comments

Fahrt is German for drive, to clear things up immediately.  Both Toyota and BMW are experimenting with the cruder form of the word, though, to bring about greener, cleaner driving.  Both have bio-energy plans that use animal and even human waste to generate methane – a greenhouse gas that when burnt, combats air pollution.  Variations on the theme may someday power our aircraft. Harold Bate and a Little Prehistory This is not a new idea.  Harold Bate, a Devonshire farmer, became a counter-culture hero in the 1970s by powering his Hillman Minx sedan with manure.  Like all visionaries, Harold was a bit ahead of his time, but became well known and envied when the Arab oil embargo of that decade …

Verdego Aero – Another Variant on VTOL Travel

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

A Controversy for Starters Skeptics abound concerning the current spate of vertical takeoff and landing (VTOL) machines.  The latest entry in the competition comes from the trio of Erik Lindbergh, Eric Bartsch, and Pat Anderson of Embry-Riddle Aeronautical University.  Their Verdego eight-rotor machine looks a bit like the Airbus A3 Vahana, but has pusher, rather than puller, propellers on the rear wing. On his Linked In page, Bartsch jumps into an ongoing fray with his article, “The Inevitability of Short-Range Urban Aviation – Why I’m Betting Against the “Flying Uber” Skeptics.” It takes aim at the opposing point of view in “Going Direct: On the Insanity of Flying Ubers,” by Plane & Pilot writer Robert Goyer.  To shorten the two …

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 …

Mike Friend Talks Hybrids in Beijing

Dean Sigler Electric Powerplants, Fuel Cells, Hybrid Aircraft, Sustainable Aviation 0 Comments

Mike Friend spent 36 years with Boeing, rising to positions as Chief Engineer and Technology Director.  His technical and linguistics abilities helped make him a world traveler, creating the first fuel-cell powered airplane in Spain, for instance, in 2002 through 2008, when the demonstrator craft first flew.  That was the first of many hybrid designs Mike would work on, with samples of his work on display this month in Beijing.  At the E-Flight Forum, sponsored by Siemens, he held forth on single-, two-, and five-seat configurations that could benefit from hybrid power. His talk, “Hybrid electric aircraft concepts, and a rational approach to success,” explained his reasoning for being enthusiastic about hybrids and showed different ways hybrid technology could be …
