Calin Gologan, founder and CEO of PC-Aero GmbH, has many electric and solar-assisted aircraft flying right now, and is responsible for the design the Aero Electric Aircraft Company’s SunFlyer training airplane, 20 of which have been ordered by Spartan Aeronautical University. The initial Elektro One has flourished in a number of variants, including the SunFlyer, a two-seat, side-by side trainer developed with George Bye in Colorado. Another variant of that original design, Solar Stratos is destined to combine record-setting altitudes with scientific research. Its banner, “Manned Flight at the Edge of Space,” highlights the craft’s intended mission to reach 80,000 feet as its initial goal, a record that will be hard to beat. Its mission is also a research venture, with Calin serving as Chief Technology Officer of SolarStratos. The initiator of SolarStratos, Raphaël Domjan, is now paddling his way through an Arctic Passage in one of two solar-powered kayaks, accompanied by Anne Quéméré, described as a Breton sailor. Their …
Your Black Friday (and All-Year) Giving List
With merchants beating the drums of commerce to lure you to their stores and web sites for holiday cheer (at least for the merchants), your editor has some alternative giving suggestions that could help bankroll the future of aviation (if not aviation futures). Each of these projects would welcome funding, and each has much to give back to all of us. Put Your Face in Space The Perlan Project has initiated a fund-raising program on Indie-Go-Go, with the immediate goal to complete construction of the major parts of Perlan II, a high-performance, high-altitude research sailplane recently featured in the New York Times. Its planned mission to 90,000 feet in the Polar Vortex could give us new and profound understanding of global climate change, the ozone hole and greenhouse gases. For a mere $15, you will, “Receive a professionally edited digital video of the entire Perlan Mission II aeronautical exploration, atmospheric science research and record breaking flights.” For another $14, you …
Perlan Project Gets Good Press in the New York Times
Science reporter Matthew Wald visited the Perlan Project in Bend, Oregon recently to see for himself an aircraft that just might conquer the heights – 90,000 feet – in a world-record attempt that will investigate the polar vortex and the ozone hole. His report in the October 21 New York Times highlights the intellectual investment in the project, with extremes of aircraft design reaching toward extreme goals. Perlan II will fly higher than any powered or unpowered aircraft in a sustained fashion. Zoom climbs in which American and Russian fighters emulated rocket ships to reach altitude records were more ballistic than controlled. Those who recall The Right Stuff will remember Chuck Yeager’s frantic and finally unrecoverable tail slide back from the edges of space. The on-line version of the story has the advantage of including a video that very nicely explains the goals and aspirations – as well as the hazards, associated with the flight. The article has brought a …
Oxis Energy and Lithium Sulfur Batteries
Taking one last look at 2011’s fifth annual Electric Aircraft Symposium, your editor regrets the fits and starts in its coverage. Next week, we’ll begin looking at the extraordinary presentations from this year’s gathering. Huw W. Hampton-Jones from Oxis Energy, a British company developing a Lithium Sulfur battery, claimed his firm’s “technology is based around the use of Lithium Sulphur to produce batteries which are superior in terms of energy, weight, cycle life, costs, ageing and safety.” Lithium sulfur is well known in military circles for providing primary (non-rechargeable) power to field operations. Perlan I flew with SAFT 5590 primary batteries, partly because of their superior energy density compared to lithium-ion cells, and partly because of their greater resistance to thermal runaways, or self-igniting fires sometimes seen in lithium batteries. Weight was a significant concern on this high-altitude craft. When working on the fringes of the battery selection effort for Perlan II, headed by Einar Enevoldson, James Murray and Eric …
Déjeuner sur le Duckhawk
This grab shot taken at the flight demonstration of the Windward Performance Duckhawk on April 22 in Bend, Oregon, resembles, in a totally accidental way, Manet’s great painting, Déjeuner sur l’Herbe (picnic on the grass). Although your editor tried convincing them, no one would doff his or her clothes to make the homage to Manet complete. Duckhawk is a beautiful, light-weight (420 pounds empty) standard-class 15 meter wingspan sailplane, stressed for over 12 G’s to enable dynamic soaring, taking advantage of horizontal wind gusts like soaring birds do – the first to be designed specifically to explore this realm of flight. It is designed by Greg Cole and built by the people who are almost done with Perlan II, designed to go to 90,000 feet. Both sailplanes will push the state of the art to new extremes. Although Duckhawk shares the look of its smaller sibling, the Sparrowhawk, it has beefier spars and a standard-class 15-meter (49.2 feet) wing with a …
