Inter-Laboratory Combat Helmet Blunt Impact Test Method Comparison

As the medical community learns more about brain injury, the importance of blunt impact mitigation becomes more apparent. As such, it is critical to make sure that research labs are not only capable of performing testing in this field, but also show inter-laboratory consistency and reproducibility. This study is a comparison between the two validated blunt impact testing labs (Aberdeen Test Center (ATC) and National Technical Systems (NTS) Chesapeake Testing Services (CTS)), and Natick Soldier Research Development and Engineering Center (NSRDEC).

Hydraulic Testing of Polymer Matrix Composite 102mm Tube Section

The objective of this research was to hydraulically pressurize the internal diameter of one 102mm Polymer Matrix Composite (PMC) over-wrapped cylinder up to 25,000 pounds per square inch (psi) and during pressurization, in real time, collect and store pressure and strain data simultaneously. Strain data must be captured from the inside diameter of the oil filled metallic cylinder and from the outside diameter of the composite over-wrap material.

Permeation Tests on Polypropylene Fiber Materials

The Toxic Industrial Chemical/Toxic Industrial Material (TIC/TIM) Task Force MFR#1 published in February 2009 focuses on inhalation hazards in an operational environment and provides a list of compounds prioritized based on toxic hazard and the likelihood of an encounter. With these types of vapor threats, cartridge-based air purifying respirators are used to protect the warfighter against chemical exposure. Traditional air purification materials often rely on porous carbons such as activated carbon or activated charcoal. Ongoing efforts seek to improve the performance of carbon materials in air purification applications as well as provide alternative materials.

DARPA-Boeing Spaceplane Completes Engine Tests

Boeing and DARPA are collaborating to design, build, and test a technology demonstration vehicle for the agency’s Experimental Spaceplane program. The Phantom Express would reinvent space missions for commercial and government customers by providing rapid, aircraft-like access to space. Within minutes, the autonomous, reusable spaceplane would launch its upper stage to deploy small satellites into low Earth orbit. It would then land on a runway to be prepared for its next flight.

Forget Joysticks – Use Your Torso to Pilot Drones

Imagine piloting a drone using the movements of your torso only and leaving your head free to look around, much like a bird. Your torso is more intuitive – and more precise – than joysticks for piloting drones, according to a recent study. Work is already underway to implement this new body-machine interface technology for search and rescue with drones.
