CAFE News: Comparing Apples, Bananas, Oranges and Doughnuts

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

One of the problems facing judges in the July Green Flight Challenge the CAFE Foundation is managing for NASA is that of determining fairly who gets the best fuel mileage.  Since “fuel” in this case can be traditional aviation gasoline, bio-diesel, electricity from batteries or solar panels, or some other energy storage medium, wildly different energy densities have to be taken into account. If TSA “freedom feels” seem intrusive, the scrutiny applied to GFC entrants and their craft will be even more onerous.  Aircraft will be impounded once inspected and registered, and the only contact pilots may have with their planes before taking off will be to “top off” their fuel tanks or batteries just before the start of their …

Green Flight Challenge: It Might Look Like a Quickie…

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 9 Comments

But it will be the Feuling Green Flight Challenger, an entirely new iteration of the Quickie “formula” if Gene Sheehan, Vic Turner, Luke Leatherman and Allon McBee have their way.  Created in the wake of the Vari-Eze’s and Long-Eze’s of the early 1970’s, the original Quickie was an 18-horsepower Onan industrial engine-powered irreducible flying machine with great speed for its low power and unbelievable fuel economy.  The team’s GFC Challenger is electric, and a far cry from its cast iron past – or the iron-horse Harley-Davidson motorcycles that are part of its surroundings. “Feuling” comes from the high-performance motorcycle and automobile developer who started the company bearing his name.  Jim Feuling had over 100 patents to his name, worked with …

Green Flight Challenge: Elektra One Progress

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Dipl. Ing. Calin Gologan, President of PC-Aero, showed the completed version of Elektra One, a Green Flight Challenge contender, at Friedrichshafen’s Expo for Sustainable Mobility in June. Over the last two years, PC-Aero has designed a series of light, electric-powered aircraft.  As Gologan explains, “Using the existent technology it is possible to fly with a one- and a two-seat aircraft without CO2-emission for more than 3 hours, without noise and for lower operation costs in comparison with classic aircrafts. This is the future of leisure aviation as a bridge to the next step: electric transportation.” Just two months after its debut at Aero 2010, Elektra One graced the halls again as part of “The Electric Avenue”.  Surrounded by electric vehicles of …

CAFE News: NASA’s Colloquia Feature Dr. Seeley

Dean Sigler Sustainable Aviation 0 Comments

col·lo·qui·um (n.) 1. An informal meeting for the exchange of views. 2. An academic seminar on a broad field of study, usually led by a different lecturer at each meeting. The Free Dictionary CAFE Foundation President Dr. Brien Seeley spoke by invitation at the Sigma Series Colloquium at NASA Langley in Hampton, Virginia on May 4th. His talk had an illustrious heritage as part of the longest-running science colloquia in America, beginning 50 years ago with a presentation by Werner von Braun, and since then including talks by Carl Sagan, Alex Haley, Neil Armstrong and other notables. Dr. Seeley was interviewed by NASA public relations TV and a local news station. Although not used to being treated like a celebrity, he found …

CAFE News: Doctors Seeley and Ford Stand and Deliver

Dean Sigler GFC, Sustainable Aviation 1 Comment

At the fourth annual Electric Aircraft Symposium, April 23 and 24 at Rohnert Park, California, two CAFE leaders provided the audience with superb presentations on CAFE Foundation’s history and future goals. Dr. Larry Ford, Vice President of the organization, led with highlights from CAFE’s past, including the scientific efforts to measure aircraft drag and provide actual numbers for comparing aircraft performance, a goal inherent in the CAFE name. He highlighted the work of many past and present CAFE volunteers (after all, CAFE is all volunteer, and a 501c.3 charitable organization promoting aeronautical research at both the grass roots and the highest levels), including the CAFE Barograph, a significant instrument that allowed objective flight performance characterization of individual aircraft and honest …

Green Flight Challenge Competitors Come Together on Perlan Project

Dean Sigler GFC 1 Comment

The Cafe Foundation’s Green Flight Challenge, scheduled for 2011, has drawn some impressive competitors with its $1.5 million prize.  Two of these, Greg Cole of Windward Performance, who will field a two-seat motorglider, and Einar Enevoldson, leader of the PC-Aero team, which will launch its Elektra One (see “PC-Aero’s Elektra One,” April 11, 2010), are working together quite collegially on a challenge of their own. Before his death in 2007, adventurer Steve Fossett, with co-pilot Enevoldson, had set the sailplane world altitude record in Perlan I, a modified Glaser-Dirks DG-500.  In a continuation of that ambitious adventure, Einar, Greg, and Project Manager Morgan Sandercock are creating Perlan II, a pressurized sailplane that will explore the realm of the nacreous, or …

Synergy and Passion at EAS

Dean Sigler Electric Powerplants, Feedback, Sustainable Aviation 0 Comments

John Palmerlee, Editor of The Flying Wire, Experimental Aircraft Association Chapter 124’s newsletter, wote this in the May 5, 2010 edition.   The CAFE Team hosted what was in my opinion a very successful event at the Doubletree Hotel in Rohnert Park, April 23 and 24, 2010. Nearly thirty contributors from around the world spoke at the Electric Aircraft Symposium, and their message was clear: Change is coming… let’s get on board together. Electric airplanes and motorcycles, model airplanes, algae biofuel synthesis, wetlands initiatives, hybrid air carriers, battery breakthroughs, VTOL PAVs, tethered wind generators, flight systems analysis, nanostructures… and a mystery Green Flight Challenge aircraft promising to tap into new design paradigms. This was just a taste of the concepts …

The Future is Electric, and Attracting Attention

FlightGlobal.com, the online version of Flight International Magazine, has an overview of the electric aircraft scene in its April 6, 2010 release.   Among the many producers and proponents of electric flight noted in the article, Dr. Brien Seeley of the CAFE Foundation is quoted extensively, as is Calin Gologan of PC-Aero in Germany, both to present at the fourth annual Electric Aircraft Symposium, at Rohnert Park, California on April 23 and 24.  The article ponders the hopes of two hybrid electric aircraft powerplant developers, George Bye, featured in a February 21 entry in this blog, and Flight Design’s Oliver Reinhardt, the firm’s technical director.  Both face the issue of retrofitting existing light planes with their new engines, and the challenge …

A Smart Electrical System for GA

Dean Sigler Uncategorized 0 Comments

Dr. Seeley made this available to Green Flight Challenge competitors. As a follow-on to your ideas for simplifying pilot licenses that I presented at Electric Aircraft Symposium III: Here is a link to a very encouraging development debuted at Sun & Fun: A comprehensive, integrated, smart electrical system for GA from Marc Ausman at Vertical Power Corporation ($1500 – $12,000). This looks like a very helpful reducer of pilot workload to help make flying simpler. The more up-scale versions offer redundancy and this technology should save weight and free up panel space as well. Also, the array of COTS eCFI/flight control options from MGL Avionics is very impressive too. Sure wish I had time to build a homebuilt aircraft with …
