One should follow Dr. Frank Anton’s Twitter account – or at least check it occasionally.  Dr. Anton is head of Siemen’s Electric Aviation Division and posts new developments regularly.  Siemens is supplying motors to Diamond Aircraft’s prototype hybrid, a tidy tri-motor if you count the engine/generator in the nose of the formerly single-engine airplane. Partnered with Austria’s Diamond Aircraft Industries GmbH, Siemens motors powered an adaptation of their DA40 four-seat airplane.  A Diesel engine/generator in the nose of the formerly single-engine machine charges two 12-kilowatt batteries behind the passenger compartment and provides power to the two Siemens motors on the canard.  The whole thing looks a bit like a large economy-size Cri-Cri. Started in 2013, the project is under the …

Eraole in Flight – Further and Higher

Eraole is a unique machine in a sea of unique craft.  Powered by a combination of sunlight, Total biofuel, and hydrogen, Raphael Dinelli’s tandem-winged biplane has been under development for many years.  With it, Raphael hopes to cross the Atlantic in 2019, Duplicating Charles Lindbergh’s 1927 flight at about half the Spirit of the Spirit of St. Louis’s speed. Eraole’s first flight took place in 2016.  The video will allow you to compare its look then with its changed appearance today. Changes of Plane, Changes of Plans Dinelli’s original plan for the flight included the use of an algae-derived fuel to run Eraole’s engine/generator.  As reported by La Tribune, though, “For four years, the Ocean Vital Foundation conducted research with …

Ashish Kumar, CEO of Zunum Aero, announced that his firm will partner with Safran Helicopter Engines to use that firm’s Ardiden 3Z engine as the powerplant for Zunum’s 10-passenger regional airliner.  He lists the advantages this installation will provide. “Our ZA10 aircraft, under development for entry in the early 2020s, will be powered by dual power sources: propulsion batteries, and a Safran turboshaft in the 1,700 to 2,000 shaft horsepower (shp) Ardiden range.  This new model, the Ardiden 3Z, will be used as a hybrid power source achieving demanding cost, efficiency and uptime requirements.  It will be coupled with an electric generator, and the integrated turbo-generator will deliver 500 [kilowatts] of electric power to supplement propulsion batteries on key stages …

Equator P2 Makes First Runway Hops

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

The Culmination of Eight Years’ Effort Tomas Brødreskift, his father and a dedicated team of volunteers have been working on a nearly no-budget, eight-year project to build a cutting-edge technology hybrid amphibian aircraft.  This past week, Equator P2’s wheels left the runway, twice on each of two days.  The team plans a full flight around the airport traffic pattern in the next few days. Although brief, the runway runs demonstrated the hand control’s proper operation, similar to the hands-only controls used on human-powered aircraft.  In that instance, the pilot’s legs are busy pedaling, obviating the need for manual operation only. In the Equator’s case, Tomas wanted simplified controls to make his aircraft a more desirable machine for future buyers.  He is, …

Two Siemens-Powered Electric Aircraft Debut

A U. S. Debut in Chicago Mary Grady, writing in AVweb, reports that “Siemens brought its prototype electric aircraft to the U.S. this week for the first time, showcasing the airplane at the company’s Innovation Day in Chicago. ‘Electric propulsion is one of the transformative technologies that will help the industry meet the goals of reduced fuel, emissions and noise,’ said Teri Hamlin, vice president of electric propulsion for Siemens. ‘By accomplishing testing on our systems on select flying testbeds in the lower power classes, we are gaining valuable experience and knowledge that accelerates and validates our other developments in hybrid-electric propulsion systems in the high power classes.’“ Testing in Waco Further testing of the technology will take place in …

Earth, Air, Water and Jet Fire

“I have always loved the desert. One sits down on a desert sand dune, sees nothing, hears nothing. Yet through the silence something throbs, and gleams.” Antoine de Saint-Exupéry, The Little Prince The SOLAR-JET project (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable JET fuel. or SOLAR-JET) pulls carbon dioxide from the air, mixes it with water and exposes the mix to 1,500 degree (Centigrade) concentrated solar energy and makes a synthetic natural gas, with oxygen as the only exhaust.  Attempting to produce a useable fuel from CO2 has been an obsession for many over several decades.  Attempts to capture and store CO2 are expensive and usually only hide the carbon, ostensibly for eternity. SOLAR-JET explains its objectives …

UAVs Push Endurance Limits

Three unpiloted aerial vehicles of wildly different configurations recently set endurance marks, each a “personal best,” with some achieving world records.  The varying designs show what can be achieved by careful aerodynamic design and efficient powerplants. Aerovel Flexrotor Sets VTOL Endurance Mark Not just a fair weather UAV, Aerovel’s unmanned Flexrotor, named for the sea nymph Actaea, “lifted off into a grey and rainy morning with 7.5 kilograms (16.5 pounds) of fuel onboard”.  According to the company, “It transitioned from hover to wing-borne flight, and soldiered on through a showery day, a blustery night, and then another day in the breezy and unsettled air behind a cold front. As dusk fell it transitioned back to hover, and dropped gently down onto …

Equator P2 Assembled, Ready to Go

Exciting new pictures from Tomas Brodreskift show that his nearly decade-long project has reached a happy completion.  The Equator P2, born in the mind of a talented industrial designer, seemed like a nice dream when your editor first saw it in renderings.  As one would expect from an accomplished product designer, the aircraft looked wonderful, set in inspiring backgrounds. A Man, A Plan, An Airplane As Tomas’ web site explains, “In 2008 the two Industrial Design students and pilots Tomas Broedreskift and Oeyvind Berven started work on the new EQP2 Xcursion, Equator’s first attempt on the light aircraft market. In this start–up phase the Equator team are working on making project assignments, design briefs, and specified diplomas that can be …

500 Miles on 10-Percent Plastic Waste

Dean Sigler Diesel Powerplants, Sustainable Aviation Leave a Comment

Plastic threatens to choke the world’s oceans, five gyres or “garbage patches” of plastic debris twirling around in toxic profusion.  These plastic bits and pieces, slowly photodegrading into smaller and smaller pieces, also choke the fish and birds that feed on or in the water.  It’s a huge problem that invites grand visions for solutions In what may at first glance seem a very small attempt to help,”Campaigning Pilot Jeremy Rowsell has made history by flying a light aircraft more than 500 miles from Sydney to Melbourne, Australia, using conventional fuel blended with 10% fuel manufactured by the UK’s Plastic Energy, from plastic waste.” Jeremy flies a Vans Aircraft RV-9A, which uses a blend of “end-of-life” plastic waste, transformed from …

A Big Win for Stuttgart Team Dipl-Ing Ingmar Geiß, Deputy Project Leader for e-Genius at the Institute of Aircraft Design at the University of Stuttgart, shared this pleasant news:  “I am happy to tell you that our hybrid-electric “ECO4” has won the Berblinger Prize 2016.  ECO4 combines an optimized electric airframe with a modern combustion engine generating electricity. This combination leads to an aircraft which cruises at 120 knots and consumes 40 percent less fuel than comparable state-of-the-art airplanes with conventional propulsion. As a further advantage, a small but powerful battery system enables a silent take-off without the combustion engine running, reducing significantly the noise emissions.”   The Berblinger Prize Gunter Czisch, mayor of Ulm, presented the 23,000 euro ($24,035 …
