NASA Test Flights Will Study Improved Efficiency of Supersonic Aircraft

NASA is set to begin a series of supersonic flights that will examine efforts to improve the efficiency of future supersonic aircraft. Future supersonic aircraft seeking to achieve a low boom will rely on a swept wing design in order to fly at supersonic speeds without producing a loud sonic boom. The swept wing design generally produces airflow disturbances that run along the span of the wing, resulting in turbulent flow, increased drag, and ultimately, higher fuel consumption.

Language Learning Robot Could Advance Autonomous Vehicles

A Purdue University researcher and his team are developing technology to give robots the ability to learn language. A team led by Jeffrey Mark Siskind, associate professor in Purdue’s School of Electrical and Computer Engineering, has developed three algorithms that allow a wheeled robot to learn the meanings of words from example sentences that describe example paths taken by the robot, to use the words to generate a sentence to describe a path of movement, and to comprehend the sentence in order to produce a new path of movement.

US, Japan Conduct First SM-3 Block IIA Intercept Test

Engineers from the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, in cooperation with the U.S. Missile Defense Agency (MDA), the Japan Ministry of Defense, and U.S. Navy sailors aboard USS John Paul Jones (DDG-53), played a key role in the first live-fire intercept using the new Standard Missile-3 (SM-3) Block IIA guided missile during a recent flight test off the west coast of Hawaii. This test marks the first time an SM-3 Block IIA was launched from an Aegis ship and the first intercept engagement using the Aegis Baseline (B/L) 9.C2 (BMD 5.1) weapon system.

Introduction to Electromagnetic Compatibility

By definition, Electromagnetic Compatibility (EMC) describes the ability of a system, a piece of equipment, or some other electrical device that utilizes electromagnetic energy, to operate in its intended environment without suffering an unacceptable degradation in its performance, or negatively impacting the ability of another device to perform its intended function.

NASA's Kennedy Space Center and the University of Miami are developing a new solid-state battery prototype that could revolutionize the way NASA operates microsatellites such as CubeSats. Rather than placing a battery in the experiment, taking up 20 to 35 percent of the available volume, the battery now resides in the payload structure, thereby opening up additional free space for researchers to perform more science.

Lomonosov Moscow State University engineers created unique polymer matrices for polymer composites based on novel phthalonitrile monomers. The materials can sufficiently decrease the mass of aircraft parts that operate at high temperatures. The high-temperature polymer composites can replace existing metal engine parts.

Smarter Prototyping — How Stratasys F123 3D Printers Make Rapid Prototyping More Accessible and Productive

3D printing’s contributions across the design, engineering and manufacturing disciplines are not new. The technology has been available for over thirty years and is often lauded as the next industrial revolution. Despite some inflated claims, there’s no denying that 3D printing has achieved its place as a valuable design and manufacturing methodology, and a cornerstone of rapid prototyping. It lives up to the promise of making businesses competitive by giving them tools streamline and enhance the product-creation processes. This white paper shows there’s never been a better time to invest in 3D printing, a fact made possible by the new Stratasys F123 3D Printer Series. These 3D printers were designed to remove barriers designers and engineers face by making the RP process more efficient and productive. Learn how the Stratasys F123 Series addresses typical rapid prototyping pain points and lets companies create better products faster, reducing the time to market.
