University Opens New Ballistics and Impact Dynamics Lab

Wichita State University’s National Institute for Aviation Research recently opened a new ballistics and impact dynamics research lab in the former Britt Brown Arena at the Kansas Coliseum. The new ballistics lab, part of NIAR’s environmental Test Labs, uses a custom built ballistic firing device to propel 22-50 caliber rounds into components inside a concrete containment building. The test is designed to simulate the impact of a structural failure on the aircraft.

Army to Get New IED Detector Technology

Detecting improvised explosive devices in Afghanistan requires constant, intensive monitoring using rugged equipment. When Sandia researchers first demonstrated a modified miniature synthetic aperture radar (MiniSAR) system to do just that, some experts didn't believe it. But those early doubts are long gone. Sandia's Copperhead — a highly modified MiniSAR system mounted on unmanned aerial vehicles (UAVs) — has been uncovering IEDs in Afghanistan and Iraq since 2009. Now, according to senior manager Jim Hudgens, Sandia is transferring the technology to the U.S. Army to support combat military personnel.

Air And Missile Defense System To Get Smarter Software

When a missile is launched against an enemy target, it would be nice to have a lot of good information about that target. But when "decision makers push the fire button, they may have very little data, and sometimes not timely enough data," said Col. Rob Rasch Jr., project manager, Integrated Air and Missile Defense Project Office, or IAMD, at Redstone Arsenal, Ala. "Nowhere in the current Army architecture is there a way to share information from all of our various sensors and weapons to have better integrated coverage," he pointed out, referring to situational awareness for those operating Patriot and other missile defense systems like those used for short-range air defense.

Oil Pipeline Fault Detection System Determines Material Permittivity at Microwave Frequencies

Researching fault location techniques for the oil industry requires data on the complex permittivity of the polyamide Rilsan at microwave frequencies. Rilsan is a vital material used in oil pipe construction. Currently there is no published data for the complex permittivity of Rilsan. The task for this project was to develop an accurate method to measure the complex permittivity of Rilsan to gain an understanding of the dielectric relaxations that occur within it. A fast, accurate method was developed using a vector network analyzer (VNA) and rectangular waveguide.

Mass Spectrometer Saves Power While Tracking Harmful Substances

British researchers who received R&D assistance from the Missile Defense Agency (MDA) are marketing a new tool that could zero in on toxic chemicals in baby formula, lead paints in toys and on walls, and poisonous substances in the blood stream.

Submersible Pressure Sensors

The AST4520 media-isolated, submersible pressure sensor from American Sensor Technologies (Mt. Olive, NJ) features a flush diaphragm steel cage design with stainless steel construction for level monitoring of turbulent tanks with viscous media. It is approved to UL/cUL913 Class 1, Division 1 IS, Groups C and D with an approved barrier. The steel cage design allows for proper flow of media while keeping the sensor at the bottom of the tank or well. It also features an engraved 316L housing and Kynar PVDF cable.

Units operate at temperature ranges of -40 to 185°F and offer pressure ranges from 0-5 to 0-15 PSIG. All units come standard with EMI/RFI protection of 100V/meter and a 4-20mA output.
