XQ-58A Valkyrie demonstrator completes inaugural flight by Staff Writers Wright-Patterson AFB OH (SPX) Mar 11, 2019
The XQ-58A Valkyrie demonstrator, a long-range, high subsonic unmanned air vehicle completed its inaugural flight March 5, 2019 at Yuma Proving Grounds, Arizona. The Air Force Research Laboratory partnered with Kratos Unmanned Aerial Systems to develop the XQ-58A. This joint effort falls within the Air Force Research Laboratory's Low Cost Attritable Aircraft Technology (LCAAT) portfolio, which has the objective to break the escalating cost trajectory of tactically relevant aircraft. The objectives of the LCAAT initiative include designing and building UAS faster by developing better design tools, and maturing and leveraging commercial manufacturing processes to reduce build time and cost. Developed for runway independence, the aircraft behaved as expected and completed 76 minutes of flight time. The time to first flight took a little over 2.5 years from contract award. The XQ-58A has a total of five planned test flights in two phases with objectives that include evaluating system functionality, aerodynamic performance, and launch and recovery systems. "XQ-58A is the first example of a class of UAV that is defined by low procurement and operating costs while providing game changing combat capability," said Doug Szczublewski, AFRL's XQ-58A Program Manager. https://www.youtube.com/watch?v=QrJmG1g4mFI&feature=youtu.be
German engineers produce and test 3D-printed rocket engine Berlin (Sputnik) Mar 05, 2019 The new method will allow the weight and production cost of a rocket to be reduced, while increasing payload and implementing more sophisticated cooling systems. German Aerospace Centre (DLR) in collaboration with SLM Solutions, have successfully created a rocket engine, called BERTA, fully assembled using 3D-printing technology. The engine, which will be used in an Ariane 6 modular rocket developed by the ArianeGroup for the European Space Agency (ESA), is capable of delivering satellites to geos ... read more
