First air-breathing, liquid fuel-powered scramjet takes flight
Before the sun had even risen over Wallops Island, Va., on 10 December 2005, a joint Office of Naval Research/Defense Advanced Research Projects Agency vehicle achieved a world first. At an altitude of 63,000 feet, the Freeflight Atmospheric Scramjet Test Technique (FASTT) vehicle became the first air-breathing, liquid hydrocarbon fuel-powered scramjet engine to fly.
After launching from the NASA Wallops Flight Facility on a two-stage, Terrier-Orion unguided solid-rocket system, the approximately 106-inch long, 11-inch diameter, missile-shaped vehicle raced at 5,300 feet per second (Mach 5.5) for 15 seconds before a controlled splashdown into the Atlantic Ocean. The FASTT vehicle project is part of the joint ONR/DARPA Hypersonic Flight Demonstration (HyFly) program and is designed to demonstrate low-cost flight test techniques and obtain in-flight engine performance data at hypersonic speeds. The overall goal of HyFly is to flight-test key technologies enabling a long range, high-speed cruise missile that can cruise at speeds up to Mach 6.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
