Army Tests Improved Multiple Launch Rocket System

Over 100 artillery rockets were launched recently at White Sands Missile Range (WSMR) to test an improved version of the M270A1 Multiple Launch Rocket System, or MLRS. The test, conducted at WSMR's G-16 impact area, saw an M270A1 MLRS vehicle equipped with a new armored cab fire 138 rockets to ensure the improvements didn't negatively impact the vehicles' mission performance.

Vibration Table Used to Test Nuclear Weapon Components

It took decades for technology to catch up with the math David Smallwood worked out to control vibration table shakers. Smallwood, a retired Sandia National Laboratories researcher who consults at the labs, knew that shaking in all directions at once was the key to realistic parts testing. Now Sandia is putting the algorithms he developed more than 30 years ago to the test by shaking up nuclear weapon components.

Army Develops Technology to Intercept Drones

As drone technology gains greater public attention, along with its potential for hostile action against American targets, Army engineers are adapting ongoing research to counter aerial systems that could threaten soldiers. At Picatinny Arsenal, the Extended Area Protection and Survivability Integrated Demonstration (EAPS ID) began as an Army Technology Objective program. The goal was to develop and demonstrate technology, which could support a gun- based solution to counter rockets, artillery and mortars (C-RAM). Research into enhanced C-RAM technology had the goal of extending the range and probability of success against the incoming threat.

World’s First Full-Color, Flexible, Skin-like Display Developed

Imagine a soldier who can change the color and pattern of his camouflage uniform from woodland green to desert tan at will. Or an office worker who could do the same with his necktie. A breakthrough in a University of Central Florida lab has brought those scenarios closer to reality. A team led by Professor Debashis Chanda of UCF’s NanoScience Technology Center and the College of Optics and Photonics (CREOL) has developed a technique for creating the world’s first full-color, flexible thin-film reflective display.

Two-Stroke Engines

Ewatt AeroSpace Company (Wuhan, China) has developed a new series of lightweight, powerful and reliable two-stroke engines for both UAV and light-manned aircraft. The engines are being designed and developed by aircraft engine designer Guido Polidoro in Ewatt’s new European Engine Development Center in Piacenza Italy. The new Ewatt engine is designed to be modular, and expandable into multi-cylinder versions to produce more horsepower. Each cylinder has 188cc displacement, developing 22 horsepower at 7500 RPM, making the single-cylinder version, at 7 kilograms, a powerful alternative to other engines on the market.

Unmanned Ground Vehicle Communications Relays

The need for a high-bandwidth communication link to carry multiple video channels from a mobile robot (unmanned ground vehicle, or UGV) back to a control station requires using high-frequency RF communication links. These links are mostly line-of-sight, often limiting the flexibility of the robot’s movement. The Autonomous Mobile Communication Relays project demonstrated the capability of autonomous slave robots to provide communication-relaying capability for a lead robot exploring an unknown environment.

30 GHz and 35 GHz Microstrip Isolators

TRAK Microwave (Tampa, FL) has announced two new Microstrip Isolators covering popular mm-wave frequency bands. Models T001110 (29.6-30.6 GHz) and T001111 (34.5-35.5GHz) integrate ferrite circulator/ isolator substrates on to printed circuit board (PCB) material providing for a high performance, yet economical, solution. Typical insertion loss is 0.8dB, return loss 20dB, and isolation of 20dB. These devices handle RF power levels consistent with T/R Module applications in phased array radar or SatCom tracking antenna systems.
