A unique chamber tests pilotless aircraft for their ability to function at altitudes exceeding 67,000 ft. Engineers at Aurora Flight Sciences Corp. (Manassas, VA) designed, built, and operate the chamber, called the Ultra-High Altitude Test Facility. Aurora successfully tested its Perseus B drone in the 12- by 7-ft chamber. Ram air coolers, normally mounted under the Perseus wing and on the fuselage's side, were replaced with compact coolers in which liquid fluids cool the engine and turbos instead of the ram air. To simulate the low temperatures at high altitudes, a special low-temperature fluid with a freezing temperature of about -130C was pumped through the coolers.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
