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.

Next-Generation Batteries Could Power Microsatellites

Daniel Perez, Ph.D., displays a piece of the prototype structure for a new solid-state battery. (Photo: NASA/Dimitri Gerondidakis) 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.

(Credit: Aleksander Babkin) 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.
