EAS VIII – A Day and a Half You’ll Never Forget

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Who would pass up a chance to stay at a nice resort, attend lectures that challenge and inspire, and meet at poolside with speakers who bring some of the sharpest minds in the world to bear on some of the biggest problems we all face?  Let’s face it.  Global warming probably won’t be going away anytime soon, and aviation seems destined to play a bigger part in polluting our otherwise near-perfect atmosphere. Unless…we learn how to make our favorite activity (in the top five for most of us, anyway), into a more responsible way to travel and recreate.  Since solving the problems which go with that responsibility will involve the best in aerodynamics, power systems and new, efficient technology, the …

Flying e-Genius for Two Years

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

At this year’s Electric Aircraft Symposium, Rudolf Voit Nitschmann, Len Schumann, and Ingmar Geiss shared their well-documented experiences with e-Genius, second place winner in 2011’s Green Flight Challenge.  Flown by Erik Raymond and Klauss Ohlmann, the airplane managed 397.5 passenger miles per gallon on its 200-mile trek around a closed circuit between Santa Rosa, California and the distant geothermal power plants that provided the electricity for its flight. As Voit Nitschmann, leader of the e-Genius team since 2005 noted, one must design electric aircraft around the beneficial aspects of such vehicles to gain the greatest performance.  Originally slated to be hydrogen powered, e-Genius mounts its 59-pound motor on the leading edge of the vertical rudder, more difficult with a heavier …

Pipistrel Shares Three New Products and Springs a Surprise

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 2 Comments

Slovenia, a tiny country which can be seen in its entirety from a light airplane, makes an astonishing array of such vehicles at the Pipistrel factory, awarded a European Union prize as the epitome of green manufacturing facilities. The company uses solar energy to power its operation and reports the number of kilowatts flowing through its plant on its web site. Naturally, we’d expect an environmentally responsible firm to build environmentally responsible products, and Pipistrel is committed to going green.  Dr. Gregor Veble, Head of Research in the Research and Development Department; and Tine Tomažič, researcher and designer, shared a multiplicity of new products and gave an all-too-brief glimpse of a surprising future project with participants at the seventh annual …

Seventh Annual Electric Aircraft Symposium Unveils New Technology

Dean Sigler Electric Powerplants, Feedback, Sustainable Aviation 3 Comments

This year’s CAFE Foundation Electric Aircraft Symposium in Santa Rosa, California had surprises from several sources, including new aircraft, batteries, and materials that will help make the future a good place to be.  Some technologies are maturing and some are about to spring forth in ways we won’t see coming. We’ll be looking at each presentation in detail in future postings, but know for certain that the electric aircraft movement is turning a corner as things become integrated in an ever-quicker progression.  We will see significant announcements in the next few months. The Symposium included not only technology, but seriously looked at how neighborhoods and society in general can integrate these new technologies in a more responsible way than the …

Panthera rollout and first engine start

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

On March 28, Pipistrel rolled out its prototype Panthera, a sleek four-seat cruiser destined to be the first production hybrid aircraft and eventually, Pipistrel’s second four-seat electric airplane. It is currently powered by a Lycoming IO-390, 210 horsepower engine.  At Pipistrel’s factory in Ajdovscina, Slovenia a team of engineers and technicians fired up the engine for the first time and performed ground runs, “verifying design parameters and engine operation.” Pipistrel’s press release quotes Ivo Boscarol, their CEO: “It is very exciting to witness the tests and see the aeroplane come to life for the very first time. This is definitely a very important milestone in the development of Panthera. We look forward to the continuation of tests and the first …

Embry Riddle Begins GFC Test Flights

On August 23, 2011, the Embry Riddle Aeronautical University’s Green Flight Challenge hybrid-powered modified Stemme S10, the Eco-Eagle, began its ground tests on the Daytona Beach International taxiways, “Getting ATC used to us!”   The next day saw several ground-skimming “flights,” starting at 2-feet, and rising to 10 and 50-feet high runs, all with the gear down.  The day’s flights ended with a trip around the pattern for the airport’s longest runway. August 25 saw a morning excursion of 45 minutes, with the airplane flying in the face of the approaching Hurricane Irene.  Test pilot Mikhael Ponso reported beautiful clouds and no high winds during the seven laps around the field.  As he tested the gear retraction and various flap settings, …

Schulz Sonoma County Airport.  The NASA-funded prize purse of $1.65M makes this the largest ever prize for aviation.  Competing aircraft must demonstrate at least 100 mph and 200 passenger MPG on a 200 mile flight.  The aircraft in the Green Flight Challenge sponsored …

5th Annual CAFE Electric Aircraft Symposium Launches New Age of Flight

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 1 Comment

Dr. Brien Seeley, founder and President of the CAFE Foundation, shares this important news. SANTA ROSA, CA.—On April 29-30, 2011, an outstanding faculty from NASA, industry and academia will present the technologies necessary to inaugurate the Age of Electric Flight.  The 5th Annual CAFE Electric Aircraft Symposium (EAS V) will reveal how safe, emission-free, 2-4 seat electric aircraft could soon make a doorstep-to-doorstep round trip from San Francisco to Los Angeles on a single battery charge at nearly twice the overall trip speed of airline travel.  The latest breakthroughs in energy storage, motors, quiet propulsion, powered lift, electronic pilot assistance, autonomous flight and aerodynamics will be presented along with proposals for how they can transform transportation. EAS V will again network …
