If you’ve managed to survive Gray Thursday, Black Friday, and a weekend of NFL games stuffed with blandishments to entice you to the nearest mall (Thanksgiving happened in there somewhere), you’re forgiven if you flinch at yet one more presumptuous tug at your purse strings. But we’re talking about helping pioneers on the edge of green technology, crafting the stuff dreams are made of – and making those dreams a reality. On this Giving Thursday, think about contributing to the dream makers who are taking us into a better future of flight. We share a few suggestions here. Solar Flight Eric and Irena Raymond are the first family of solar-powered flight, now cruising Italian skies in the world’s first two-seat sun-powered airplane, the Duo. To assist with further development of their splendid aircraft, including Sunstar, a high-altitude surveillance and communications craft, the couple is selling a beautiful calendar featuring their aircraft. For $37 US or 29 euros plus shipping, you …
Green Flight Challenge Final Results
Steve Williams, CAFE Foundation board member and e-totalizer guru, released the final results for the NASA Green Flight Challenge sponsored by Google, held at the Charles M. Schulz Sonoma County Airport from September 25 through October 1, 2011. Figures show a profound difference between the two electric winners and the two gas-powered and hybrid runners-up. All competitors flew extremely clean motorgliders with demonstrated lift-to-drag ratios between 25:1 and 35:1. Possible explanations for the large differences in energy use include low cooling drag for electric aircraft and the efficiency of electric motors – but the differences are still surprising. Note that a little over 11 US gallons of gasoline (energy equivalent) were used to fly seven people (Embry Riddle’s Eco-Eagle flew with only one pilot) over a total of 725.5 miles (Embry Riddle flew a shorter total distance on both “runs”). This is an enormous achievement for all concerned and a significant increase in efficiency over even the best general aviation craft available today. Congratulations are …
CAFE News: Doctors Seeley and Ford Stand and Deliver
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 comparisons between aircraft. Larry let audience members know about the contributions of Jack Norris, and his creation of “zero thrust glide testing.” This innovation involved finding the point at which the propeller was not creating drag or producing thrust. At …
