Things are Looking up in Dubai

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

Clean Technica recently examined whether the United Arab Emirates, and especially Dubai could become a world leader in clean mobility. It lists factors such as one of the heaviest concentrations of concentration of EV charging facilities in the world, and the sizable discounts the state gives on EV ownership. The state’s relationship with electric car suppliers and readiness to test sky taxis from eHang and Volocopter add to the mix.  Dubai has its homegrown flight vehicles that will add to the aerial circus in its desert skies. DGWorld, a major source of robotics in the country, has two such craft on the horizon. DG World’s Contribution The smaller of the two, the “flagship drone of DGWorld,” the UAD M20 has …

Simulations May Stimulate Better Hybrids

Phillip Ansell, assistant professor in the Department of Aerospace Engineering in the College of Engineering at the University of Illinois explains the benefits and downsides of fossil fuels. “Jet fuel and aviation gasoline are easy to store on an airplane. They are compact and lightweight when compared to the amount of energy they provide. Unfortunately, the actual combustion process is very inefficient. We’re harnessing only a small fraction of that energy but we currently don’t have electrical storage systems that can compete with that.” Ansell and colleagues are striving to use simulations to increase the range of hybrid aircraft.     Batteries provide their own set of problems. He explains that adding more batteries to go farther may have a certain logic, for …

Volocopters to Fly Doctors

Dean Sigler Announcements, Electric Powerplants, Sky Taxis Leave a Comment

Helena Treeck of Volocopter alerted your editor of an exciting development for the multicopter manufacturer.  ADAC Luftrettung (ADAC Air Rescue) wants to use volocopter’s capabilities to take doctors or other qualified medical personnel to points of need – and rapidly.  ADAC’s slogan, “Against time and for life,” sums their mission, and Volocopters seem apt choices to help fulfill it. Rotary-wing aircraft have a well-established reputation for rescues in treacherous locales and circumstances.  An outstanding job of flying earlier this year on Mt. Hood, Oregon highlights this. Electric vertical take off and landing craft may be even better at this than fossil-fuel powered ones.  They don’t run out of oxygen at altitude – the rescue on Mt. Hood took place near …

David Ullman Receives Patent on IDEAL Airplane

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

David Ullman a Professor Emeritus at Oregon State University, has used his expertise in mechanical engineering to design his IDEAL airplane.  That stands for Integrated Distributed Electric-Augmented Lift, and like all good projects with good acronyms, almost explains itself.  Recently, the U. S Patent office thought the IDEAL is worthy of being patented. It might be helpful to read the full patent, filed with working partner and neighbor Vincent Homer, because the ideal looks simple, but has years of development behind it.  The two live in Independence, Oregon, on an airport that includes hangars on every house and taxiways linking them to the main runway.  Both their hangars are filled with evidence of their skilled handiwork.  Vincent’s houses giant models …

Terrafugia’s TF-2

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

Terrafugia, unabashedly calling its vehicles “flying cars” in many of its public pronouncements, has floated a concept that is a serious departure from their two previous designs.  The TF-2 will be the equivalent of a shuttle bus, but with an aerial means of making a longer haul than mere in-town hops. Started by MIT graduates, many of them members of the rocketry club, Terrafugia has managed to garner an enormous number of media hits.  It even became a possible Christmas gift in the 2010 Hammacher Schlemmer Christmas catalog. It flew its Transition before the crowds at AirVenture in 2013, and was able to obtain certification as a Light Sport Aircraft since then, but with a slightly higher than original LSA …

Volocopters to Hover Over Singapore

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

Helena Treeck from Volocopter sent the following message this morning: “Bruchsal/Paris/Singapore, October 2018 – Volocopter, the pioneer in urban air mobility, announced today during Autonomy – the Summit of Urban Mobility in Paris, that they will perform a next set of inner urban flight tests in Singapore. The series of test that are scheduled to take place in the second half of 2019 are supported by the Ministry of Transport (MOT), Civil Aviation Authority of Singapore (CAAS), and Economic Development Board (EDB).” Already undergoing testing in Germany and Dubai, Volocopter’s 2X appears to be the company’s flagship for continuing development.  The following video (in French) intercuts a representative explaining the benefits of the Volocopter with images of its public flight …

HES Element One Could Fly Four 5,000 Kilometers

Dean Sigler Fuel Cells, Hydrogen Fuel, Sky Taxis, Solar Power, Sustainable Aviation Leave a Comment

Horizon Energy Systems (HES), originally based in Singapore, has pursued lightweight hydrogen propulsion systems for the last 12 years, primarily for amall drones.  Going larger, the company announced plans today for Element One, “the world’s first regional hydrogen-electric passenger aircraft.” A four-passenger, 14-motored (!) monoplane, Element One will carry the lucky foursome 500 to 5,000 kilometers (310 to 3,100 statute miles).  This distributed power system claims “virtually no change to its current drone-scale systems,” which is a little puzzling, considering the largest of such systems produces no more than 1,000 Watts.  The scale of the Element One and its power packs is ambiguous, with illustrations showing a nine-axle trailer with attached solar panels ostensibly powering the on-site production of H2. …

VerdeGo’s Integrated Distributed Power System

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

Erik Lindbergh, grandson of the famed trans-Atlantic flight pioneer, has been paying his dues in aviation for decades, working to involve young people in career-building roles, and advocating for “green” aviation.  His latest roles have found him mentoring a group of Embry Riddle students in developing an electric HK-36 (shown last year at AirVenture), and in developing one of the over 100 electric vertical takeoff and landing (eVTOL) potential sky taxis coming into public view.  That sky taxi may not make it to market, but Lindbergh and partners’ Integrated Distributed Power system is headed that way. At the 2017 AirVenture, he shared the news that he was working on something exciting.  That turned out to be the VerdeGo project, an …

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 …
