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 …

Dean Sigler Announcements, Hybrid Aircraft, Sustainable Aviation 0 Comments

Taja Boscarol, Public Relations Manager for Slovenian aircraft company Pipistrel, announced the formal establishment of the fourth company of the Pipistrel Group at the Chamber of Commerce in Jurong City (Jiansu Province), China. The new company, PIPISTREL ASIA-PACIFIC, General Aviation Technology Co. Ltd. was founded by Ivo Boscarol (51-percent owner) and Danny Wu Hao (49-percent).  Hao, as financial partner, will provide the capital investment required for the construction of Project Jurong. The ownership of both Slovene companies, Pipistrel d.o.o. and Pipistrel Vertical Solutions (a new development under control of Tine Tomazic) remains 100-percent Slovenian as before. As Ms. Boscarol’s press release relates, “From now on, the PIPISTREL ASIA-PACIFIC, General Aviation Technology Co. Ltd company is the general distributor of Pipistrel …

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 …

Ampaire and its Zero Emission Airplane

Dean Sigler Electric Powerplants, Hybrid Aircraft, Sustainable Aviation 1 Comment

Ampaire, a California-based startup, has a simple, two-fold set of goals.  Its TailWind™ aircraft will solve the problems of high operating costs for short-haul airlines and reduce emissions by 99 percent.  They must make a compelling argument since they won one of ten awards at the recent the 2017 Hello Tomorrow Global Summit Deep Tech Challenge in Paris.   Kevin Noertke, CEO of the firm, presented a brief but energetic rundown on the company’s goals and the elegant aeronautical offering he and co-founders Cory Combs (CTO) and Ryan Bilton (CFO) envision.  Note the crowd, the band, and the high production values of the Summit. Your editor wondered about the “Powered By” reference to Airbus.  Kevin cleared that up in an …

e-Genius Gets Around Quickly, Inspires Others

Birds of the Same Tail Feather Configuration Prof. Dipl.-Ing. Rudolf Voit-Nitschmann (emeritus) had a lot to do with designing the 1996 Icare II solar-powered sailplane and the 2011 e-Genius.  Icare II set several world records in its 20 years, most under the guidance of pilot Klaus Ohlmann.  e-Genius won the award for being the quietest airplane at the Green Flight Challenge held in Santa Rosa, California, and was a close second to Pipistrel’s G4 in passenger miles per gallon (equivalent) energy use. Dipl.-Ing. Voit-Nitschmann was kind enough to explain to your editor how the propeller center came to be at the top of the tail on e-Genius.  It’s a similar configuration to that on the Icare II*, and one he …

Hoversurf and OTSAW Patrol the Skies of Dubai

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

Hoversurf’s recent announcement of its use by Dubai police to patrol the streets and skies of the capital city brings forth several questions.  With Dubai and other Emirates readily encouraging new modes of transport, including sky taxis and possibly Hyperloop trains, the country seems set to lead a transportation revolution in the 21st century. Already, style leaders and plutocrats crowd the streets with Lamborghinis and Bugattis: the police force fielding equally formidable patrol vehicles to control over-eager drivers.  Police inventories include a Brabus-tuned 690 horsepower Mercedes Geländewagen capable of off-road desert sorties, and at least one $1.6 million Bugatti Veyron for on-road speeders, along with a Porsche 918 and various Aston Martins.  Several other supercars ensure a fairly even pursuit …

Boeing Announces Zunum Progress, Acquisition of Aurora Flight Sciences

Dean Sigler Announcements, Electric Powerplants, Hybrid Aircraft, Sky Taxis, Sustainable Aviation 0 Comments

Boeing made two announcements this week that show the maker of large aircraft willing to investigate niche markets at smaller scales and with more personal service for flyers.  Both involve electric power and the potential for automated flight. Zunum To Fly by 2020, In Service by 2022 Zunum Aero, the Boeing- and Jet Blue-backed regional airliner startup, will begin development of a 10-to-12 passenger airplane, hybrid powered with large electric ducted fans at the rear of the fuselage.  Having flown on earlier examples of 10-passenger “airliners,” your editor welcomes this smaller package.  Ford Trimotors and DeHavilland Dragons carried passengers in the 1930s, with simple accommodations and window seats for all.  The single-aisle made boarding and deplaning easy and quick, and …

A Range Extender You Can Ride Home

Dean Sigler Electric Powerplants, Hybrid Aircraft, Sky Taxis, Sustainable Aviation 1 Comment

Range extenders make any airplane to which they are attached a hybrid aircraft, with an engine-driven generator charging batteries or driving one or more electric motors that provide thrust.  Speaking today at the 7th EASN International Conference on Innovation in European Aeronautics Research, Richard Glassock, a Fellow at the Institute of Aerospace Technology at the University of Nottingham, gave the range extender a completely new mission. His innovation comes in two versions, the RExLite and RExMoto.  RExLite is a simple generator drive that mounts under the aircraft.  RExMoto looks similar – a streamlined pod under the aircraft – but can be converted to a motorcycle when on the ground.  Both “use conventionally-fueled combustion-engine-driven electrical generators to provide energy at peak …

Zeppelins, Blimps and Plimps

How about exploring a softer, gentler form of flight?  Certainly, gas-filled envelopes provide a large way to transport goods and people, but for a variety of reasons, have fallen out of favor in recent years.  Several entrepreneurs are trying to revive an old idea. Hanging Over Our Heads One threat hanging over our heads is that of plummeting drones, either having exhausted their short-range batteries or banging up against a tall building.  The infamous video of a drone falling onto a woman in Seattle has been removed from YouTube, probably for legal reasons, but an abundance of others are there for your viewing pleasure. Maybe More Truth than Poetry Alfred Lord Tennyson wrote a prescient bit of poetry in 1835, …
