In the Small World category, the team leader of the 2011 Green Flight Challenge winning team is designing the next generation of a drone that can carry blood and stool samples from remote and otherwise inaccessible parts of Madagascar to a central laboratory where the samples can be analyzed.  Jack Langelaan, Professor of Aerospace Engineering at Pennsylvania State University, is working with Vayu Aircraft to develop a vertical takeoff and landing machine specially crafted to meet the needs of the ValBio Centre. The video shows an early version of the drone, while pictures on Vayu’s web site depict a sleeker, more refined approach.  The functionality for both machines would seem to be identical, but the styling for the projected future …

Brien Seeley forwards a video of Pipistrel’s historic, Collier Trophy nominated electric powered flight.  He notes, “It applies its performance data file and a weather map overlay to annotate scenes of the visual beauty of the Sonoma Wine Country,” a feature that will also delight visitors to Charles M. Schulz Sonoma County Airport when they attend the electric aircraft flight demonstrations that are part of this year’s Electric Aircraft Symposium. The Team will present details of their aircraft and its achievement at the 6th Annual CAFE Electric Aircraft Symposium on April 27, 2012 in Santa Rosa, for which registration can be obtained online. The video will remind one of the weather overlays Dr. Jack Langelaan created for his autonomous soaring exercises, and …

Pipistrel had a good week at Oshkosh.  Shortly after its G4 placed ninth in the Dead Grass Awards, an indication of the number of spectators who tramped around the perimeter of the displayed aircraft,  the company could announce the first test flight of the four-seat electric motorglider. “We are pleased to announce that after long and demanding work nearly of a nearly 30-member team of developers and constructors from Pipistrel’s R & D Institute the first 4-seat electric aircraft in the world took off this morning [August 12, 2011] at 7 AM local time.” Pipistrel overcame several difficulties in achieving this milestone.  Developing the electric power system, the most powerful currently in an aircraft, and importing the 450 pounds of …
