The U.S. Air Force and General Electric (GE) have begun the Phase 2 testing of GE’s second XA100 adaptive cycle engine at the Air Force’s Arnold Engineering Development Complex (AEDC) in Tennessee.

The Phase 1 testing of this XA100 engine was completed in November 2021 in Evendale, Ohio. Developed by GE Edison Works advanced program unit, the XA100 is a three-stream adaptive cycle engine demonstrator that can direct air to the bypass third stream for increased fuel efficiency and cooling or to the core and fan streams for additional thrust and performance.

GE’s XA100 engine is uniquely designed to fit both the F-35A and F-35C without any structural modifications to either airframe, enabling better aircraft range, acceleration, and cooling power to accommodate next-generation mission systems, while also ensuring durability and enhanced readiness.

How the Japanese manufacturer YKK has stayed at the top of its industry.

US home prices have soared to new heights and they keep on climbing, and some researchers and economists say they have seen signs of a housing bubble brewing.

Home prices are rising faster than market forces would indicate they should and are becoming “unhinged from fundamentals,” according to a new blog post written by researchers and economists at the Federal Reserve Bank of Dallas.

Until recently, the possibility of a bubble wasn’t widely supported. But after looking at housing markets across the US, the Fed researchers said new evidence is emerging.

Even before Russia invaded Ukraine, the fuel that runs the global economy was in short supply.

Now some analysts say there could be spot shortages of diesel fuel and prices may stay elevated, even if oil and gasoline decline.

Those higher diesel fuel prices are also stoking inflation.

If true, this idea could even help us understand all of the dark matter in our universe.

Trying to make sense of information is a universal daily experience. For physicist Melvin Vopson, this pursuit goes well beyond the mundane—he’s trying to prove that information has a physical presence. It’s a weighty task that could lead to new insights about how we can manage the future of information storage. It could also lead to a fundamental shift in how we think about the universe.

Vopson, who studies information theory at University of Portsmouth in the United Kingdom, wants to use an experiment to confirm that elementary particles have measurable mass. It would involve a matter-antimatter annihilation process that would shoot a beam of positrons at electrons in a piece of metal. Positrons and electrons are both subatomic particles, with the same mass and magnitude of charge. However, positrons are positively charged, and electrons are negatively charged.

Siemens and Roboze have announced that they are collaborating to develop workflows dedicated to the industrialization of 3D printing. This includes an emphasis on expanding the use of the technology in energy, mobility, and aerospace. Though the exact nature of the agreement isn’t fully elucidated, it marks a significant shift for both firms.

Siemens is the largest industrial manufacturer in Europe, with a storied history spanning nearly two centuries and annual revenues totaling €62.3 billion, as of 2021. In contrast, Roboze is a comparatively new firm, established in Italy in 2013. The company has since built itself up into a leader in industrial-grade material extrusion 3D printers, earning such customers as Ducati, GE, and the U.S. Army.

The partners do not exactly clarify their intent except to say that they will work together to “increase the productivity, competitiveness and efficiency of manufacturers that have embarked on the path to the future of industry.” They do mention focusing on “digitalization and automation projects”.
