Elektra One Solar or Luminati VO-Substrata?

Dean Sigler Solar Power, Sustainable Aviation 0 Comments

Your editor saw a news item from Sun ‘n Fun about a new solar-powered airplane and recognized the design as one from Calin Gologan’s PC-Aero, an aircraft design and consulting firm in Germany. General Aviation News credited the airplane’s design and construction to Luminati Aerospace in New York state.   The story did not mention Gologan’s involvement, though, a possible oversight.  An alert reader commented on the similarity of the airplane to the Elektra One Solar. A few months later, your editor saw an Associated Press story from Calverton, New York, which explained, “Pilot Robert Lutz flew the VO-Substrata aircraft for about 20 minutes in the first test flight opened to the public. The white aircraft features wing-mounted solar cells and has a wingspan …

Phil Barnes, aviation consultant, opened each days’ sessions at this year’s Electric Aircraft Symposium: on Friday with a talk on dynamic soaring as taught by the birds, and on Saturday on regenerative power to keep a dynamic soaring aircraft in perpetual flight without any outside energy source other than the sun. Phil has 31-years of experience in the performance analysis and computer modeling of aerospace vehicles and subsystems at Northrop Grumman. He has been to Antarctica twice to photograph and study the flight dynamics of the Albatross, lessons he applies to the ideals of dynamic soaring and energy retrieval in flight. His Friday morning talk, “How Flies the Albatross,” discussed the flight mechanics of dynamic soaring, that mode of maintaining …

A Comparison Too Far

A recent entry comparing the German Carplane® and Burt Rutan’s BiPod has prompted a response from John Brown, who found the posting of concern for the misapprehensions it might cause in readers. He notes, for instance, “Your current article portrays us as a large Govt. Co. (we got a small subsidy) going up against a ‘charity’ organization (Northrop-Grumman’s subsidiary, Scaled Composites) in whose name the BiPod is registered at the FAA – as a glider; “It compares us to 1930s modular concepts where actually the BiPod’s wings are screw-on/screw-off ‘modular’ and use that older concept; “It attributes a commuter ‘pitch’ to us where, in fact, we’re not aiming for that market at all.
