GoFly and Win Big Prizes

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

“Have You Ever Dreamed of Flying?” Boeing asks, and answers its own question: “We’re making that dream a reality.”  Well, actually, the person entering HeroX and Boeing’s GoFly competition will make their own dream a reality, and possibly win substantial sums in the process. Abundance Insider, an Internet outreach from Peter Diamandis, himself well-acquainted with prize competitions, gives an excellent short rundown on the competition. “What it is: HeroX recently announced the GoFly Prize, sponsored by Boeing — a $2 million challenge to create a personal flying machine that is useful, safe and thrilling (italics by the editor). The goal is to foster the development of a safe, quiet, ultra-compact, near-VTOL personal flying device capable of flying 20 miles while …

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 …

The Lightest Material Encapsulated in the Sheerest

Scientists may have come up with a process to wrap hydrogen-trapping magnesium with an atom-thick layer of graphene, setting up a scenario to store hydrogen in a weight-saving way. Hydrogen seems to be a perfect fuel, but like all perfect things, an unattainable one.  Its lightness and smallness make it hard to contain, and pressurization required to store it adds weight to its containers.  Flying since 2009, the Lange Antares DLR-H2 has been a test bed for hydrogen-fueled flight.  The DLR (Germany’s NASA) explains, “The developers selected a new, larger pressure vessel that, at 350 bar (5,076 pounds per square inch), now holds five kilograms of hydrogen to replace the previous tank in the external pod on the starboard wing, …

Volocopter Starts Autonomous Air Service Trials in Dubai

Dean Sigler Sky Taxis, Sustainable Aviation 0 Comments

In June, Dubai’s Road and Transit Authority (RTA) announced its plans to test fly Volocopter’s 200 over the country by the last quarter of this year.  The government and Volocopter have succeeded in meeting that timeline, with demonstrations this week of Volocopter’s quiet ability to fly autonomously (although without passengers so far).  Aerial transit will be a small part of a much broader scheme, the government intent on providing excellent public transportation, as shown in this well-produced video. To ensure meeting Dubai’s ambitious goal, Volocopter’s designers tested the machine thoroughly in German skies.  Note the Grob Strato 2C by one of the hangars, the twin-engined airplane in which Einar Enevoldson, founder of the Perlan Project, set the still extant world …

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, …

On August 30. Pipistrel inaugurated the first electric charging station to fully warrant the name, charging one of their own Alpha Electro trainers.  The project was co-financed by the Ministry of Education, Science and Sport and the European Union from the European Social Fund.  Led by Pipistrel, the LECAD Laboratory, and the Academy of Fine Arts and Design, mentors and students developed and constructed a fully-functioning station. Technical characteristics of the charging station:  – capable of charging two electric aircraft at the same time – current strength: 2 x 20 kW – charge speed: one hour to fully charge Alpha Electro – operating voltage 3f 400V AC – WiFi connection to the network As Pipistrel explains, “The goal of the …

HopFlyt Channels the Custer Channel Wing

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

HopFlyt is an enthusiastic young organization devoted to renewing the Custer Channel Wing, a lost remnant of attempts to create extremely short takeoff and landing (STOL) airplanes starting over 70 years ago.  Their web site explains their primary goal, which includes adding electrically-powered vertical takeoffs and landings to the channel wing’s repertoire. “HopFlyt is an aviation technology startup company [whose] main priority is to develop technology and ultimately build a sustainable electric Vertical Takeoff & Landing (eVTOL) aircraft. The goal of this aircraft is to help you beat the jam of traffic and reduce pollution in major urban centers around the world. We want to change your 2 hours of traffic into a short 20 minutes of flying.” Willard Custer’s …

Sun Flyer’s Two and Four Seat Electric Aircraft

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 0 Comments

George Bye has spent the last decade developing a viable two-seat training aircraft that would be electrically powered.  His efforts included a Cessna 172 that took wing on battery power, and have evolved to the current product, a sleek two-seater that has 105 deposits to buy worldwide. At AirVenture 2017, George displayed the Sun Flyer 2 and announced plans to introduce a four-seater, the Sun Flyer 4.  With ground tests complete on the aircraft and its 45-pound Emrax motor, George envisions flight tests coming this fall for the 2.  Even given successful flight tests, certification may take two to three years.  George has been working with the FAA to enable certification under Part 23 rules, and has made great headway …

A123/Solid Power Partnership – A Safe Bet?

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

A123 Systems has worked with buffering chemistries to reduce the volatility of lithium batteries for the last decade.  Solid Power Inc. has taken a set of interesting new technologies to make batteries more energy dense and safer.   The two companies are combining efforts to make a more powerful, less-volatile battery, according to recent press releases. A123 produces nanophosphate (lithium iron phosphate – LiFePO4) and ultraphosphate batteries.  Their nanophosphate batteries are used in Porsche’s 919 hybrid, a LeMans Prototype (LMP1) endurance racer that was outright winner of the event this year.  They also power Eva Hakansson’s Killajoule and Bill Dube’s Killacycle – both record-holding electric motorcycles.  Their Ultraphosphate line is designed to work at low voltages and low temperatures, including 48-Volt …

SmartFlyer Challenge: Electric Airplanes Fill Swiss Skies

There are few times one will see more than one electric airplane at the same place – outside of perhaps, Friedrichshafen’s e-Flight Expo every year.  But to see them flying at the same field on the same day is an even grander delight.  That happened September 9 and 10 at Grenchen, Switzerland.  Grenchen hosted the world’s first all-electric fly-in – the SmartFlyer Challenge.  It drew an appreciable number of electric aircraft of all sizes and types despite the clouds and rain that kept some from scaling the mountains. An Electric Three-Plane Formation Flight The Siemens-powered Magnus e-Fusion from the Czech Republic, the electric Phoenix motorglider, and Stuttgart University’s e-Genius all flew formation with a Piper L-4, a World War Two …
