3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. 3D printing is also revolutionizing defence…
As of May 2021, there are about 4,300 active artificial satellites currently orbit Earth. We rely so much on satellites for so many things in our lives, and we count on them to be durable and reliable. When satellites don’t…
The jet engine is the most complex element of an aircraft and one of the most complex human-made products ever developed, housing thousands of individual components — and ultimately determining fuel efficiency for aircraft All turbines operate on similar…
Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidizer, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet…
In 2018, The American Society of Mechanical Engineers (ASME) named the Pratt & Whitney single crystal turbine blade an historic mechanical engineering landmark. These blades, which can be found in many modern, high-performance gas turbines (a.k.a. jet engines)—including the ones powering…
The COVID-19 pandemic, while demonstrating the nation’s vulnerabilities to biothreats, has also shown the fragility of the supply chain. The United States relies on foreign suppliers for a number of critical components including commodity chemicals, rare earth elements and active…
The Department of Defense (DOD) acquires goods and services from contractors, federal arsenals, and shipyards to support military operations. The acquisition is a broad term that applies to more than just the purchase of an item or service; the acquisition…
We live in an increasingly interconnected world, one in which mobile communications provide a significant element of this interconnectivity. This increasing demand for high speed, low latency networks supporting mobile connectivity is leading the definition of 5th generation mobile networks.…
Two out of three missions to the red planet have failed. One reason there have been so many losses is that there have been so many attempts. “Mars is a favorite target,” says Dr. Firouz Naderi, manager of the Mars…
We are in midst of the second quantum revolution moving from merely computing quantum properties of systems to exploiting them. Researchers are developing new capabilities in secure communication, ultra-sensitive and high signal-to-noise physical sensing of the environment and Quantum Information…
