Touring on Sunbeams Eric and Irena Raymond have an enviable life, traveling on sunbeams across Europe in their Sunseeker Duo, and if plans go well later this year, into northern Africa and beyond.  “Last summer, we flew down the west coast of Italy, landing on the islands of Elba and Corsica.”  Crossing the Mediterranean would be no major impediment to further travel, as Solar Impulse showed, because, “Being solar powered our airplanes are assured a constant supply of energy by flying over the clouds, and we can cover much greater distances.” This summer will expand their itinerary to, “Starting in Italy and flying down the Dalmatian coast of Croatia, starting by exploring the Istria peninsula, then touring the myriad countless islands of this Adriatic archipelago.  No goal is set, other than returning to our home base in Osoppo (Italy). At least as far as Split should be easy.”  Split, on the west coast of Croatia, includes the palace of Roman …

Unveiled at the Dubai Air Show this week, the collaborative effort between Stratasys and Aurora Flight Sciences is the largest and fastest 3D-printed aircraft so far.  With a 9-foot wingspan and weighing 30 pounds, the unmanned aerial vehicle is also the first jet aircraft to be made through additive manufacturing. 80 percent by weight was made through the advanced process, the rest consisting of the engine, electronics and tires.  Because the airplane was designed in a collaborative computer aided design process, the parts could be printed in Stratasys’ facilities even though they were designed primarily in Aurora’s Virginia headquarters. Besides saving weight, the process saves time, the complete aircraft going from initial idea to first flight in under nine months. Scott Sevcik, aerospace and defense business development manager at Stratasys, and a recent presenter at the ninth annual Electric Aircraft Symposium, says, “Aurora wanted to look at the feasibility of producing a vehicle tailored to unique mission requirements.  They identified …
