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

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.

Polymer Material Decreases Mass of Aircraft

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.

Fluctuating Forces of Flight Captured by High-Tech Paint

A rocket is buffeted by a chaotic flow of air during flight. At high speeds, airplanes experience a similar, unsteady flow of air over their wings. A method to precisely measure these fluctuating forces uses pressure-sensitive paint (PSP), called Unsteady PSP, which emits a bright crimson glow in the presence of high-pressure airflow.

Discovery Could Lead to Cleaner, More Efficient Jet Engines

Researchers at The Ohio State University found a way to improve the high-temperature properties of superalloys used in jet engines. The method tailors an alloy’s composition and exposes it to high heat and pressure to prevent microscopic defects from forming, actually making the alloy stronger. This “phase transformation strengthening” eliminates the formation of defects and decreases alloy deformation by half. When an engine can run at very high temperatures, it consumes its fuel more thoroughly and produces lower emissions.

NRL Develops Novel Monolayer Ferroelectric Hybrid Structures

Scientists at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, have demonstrated that the intensity and spectral composition of the photoluminescence emitted from a single monolayer of tungsten disulphide (WS2) can be spatially controlled by the polarization domains in an adjacent film of the ferroelectric material lead zirconium titanate (PZT). These domains are written in the PZT using a conductive atomic force microscope, and the photoluminescence (PL) is measured in air at room temperature. Because the polarization domain wall width in a ferroelectric can be as low as 1-10 nm, this approach enables spatial modulation of PL intensity and the corresponding carrier populations with potential for nanoscale resolution.

Satellite Communications Ball Offers More Bandwidth, Greater Portability

While it may resemble a giant beach ball, the inflatable ground antenna transmit and receive (GATR) ball is actually the Army's latest piece of satellite communications equipment. The technology is so new that the 369th Sustainment Brigade's GATR ball has a serial number in the single digits. Designed to be lighter and more compact than traditional, rigid satellite dishes, the GATR ball can be broken down into just a few cases and hand carried anywhere in the world. The self-contained system can then be inflated and set up in less than two hours, ready to provide a variety of communication services.
