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. …

This year’s Icarus Cup, a human-powered flight competition, was held at Sywell Aerodrome, about 75 miles and nearly two hours north of London.  The Royal Aeronautical Society hosted the first Icarus Cup last year, and explains its origins and purpose.  “In 2011, we commemorated the 50th anniversary of the first flight by a human powered aircraft. The origins of human powered flight begin in 1959, when the Royal Aeronautical Society Human Powered Aircraft Specialist group was formed. Two years later, November 1961 marked the first human powered flight by Derek Piggott. Since then, human powered aircraft enthusiasts have been competing for the Society’s Kremer Prizes . “One of the Human Powered Aircraft Group’s objectives is to promote human powered flight as a sport …
