Processing and Characterization of Lightweight Syntactic Materials

Conventional composite materials, in which a matrix material is reinforced by particulates, whiskers, and/or continuous fibers, have long been of interest as potential materials solutions to engineering needs. Typically, the benefits of these reinforcements are observed for cases of tensile loading, with only minimal improvement for cases of compressive loading. As a result, recent attention has grown in the use of hollow spheres as a potential reinforcement in metallic systems.

Mechanical Characterization and Finite Element Implementation of the Soft Materials Used in a Novel Anthropometric Test Device for Simulating Underbody Blast Loading

Anthropomorphic test devices (ATDs) have been used in automotive safety research since the 1970s to predict injuries. ATDs must repeatedly perform under a dynamic range of loading rates and reliably distinguish between injuries ranging from minor to severe.

Stress-Corrosion Cracking and Corrosion Fatigue Impact of IZ-C17+Zinc-Nickel on 4340 Steel

The protection of cathodic metallic materials used for aircraft components, like 4340, Aermet 100, and PH 13-8 corrosion-resistant steel, is critical to keeping the steel from pitting and cracking due to exposure to the operating environment. Two important properties are resistance to stress-corrosion cracking (SCC) and corrosion fatigue. These are insidious failure mechanisms that can lead to part failure in service.

High-Reliability Capacitors

Maintaining technological superiority remains critical for national defense forces. Many face informal adversaries that are adept at harnessing today’s sophisticated civilian technologies, like mobiles, M2M communication and social media, to launch attacks unexpectedly. Defense operations are intelligence-led; responses must be surgical and precision-guided to avoid harming civilians; and every measure must be taken to avoid injury to soldiers or loss of equipment. At the same time, government funding of defense forces, particularly in the West, is under pressure.

The newest crash test dummy in development is actually a blast test dummy. WIAMan (Warrior Injury Assessment Manikin) is a ground-breaking anthropomorphic test device (ATD) being developed by the U.S. Army. It’s the first test dummy designed specifically for vertical loading in under-body blast (UBB) scenarios, like the ones soldiers may experience in combat from IEDs. A key goal of the program is to develop a scientifically-valid injury criteria for blast testing of military ground vehicles. This test data will be the most advanced of its kind and will be used to develop new, safer vehicles and associated equipment to help reduce injury risk for warfighters. Another first coming out of this program is the high-tech data acquisition system that is entirely contained within the dummy, making it the first completely autonomous device of its kind.

3D Printed Aircraft Parts

Stratasys Direct Manufacturing
Valencia, CA

Stratasys Direct Manufacturing, a subsidiary of Stratasys Ltd., was recently chosen by Airbus to produce 3D printed polymer parts for use on A350 XWB aircraft. The company will print non-structural parts such as brackets, and other parts used for system installation, on Stratasys FDM production 3D Printers using ULTEM™ 9085 material. The project will help Airbus achieve greater supply chain flexibility and improve cost competitiveness, while leveraging on reduced material consumption and waste.

Sensors Detect Aircraft Damage as it Occurs

The Army developed and tested networked acoustic emission sensors that can detect airframe damage on conceptual composite UH-60 Black Hawk rotorcraft. The sensing method can be used to reliably detect and locate the initiation and growth of damage that may occur during service.

NASA Unveils the Future of Science Drones

NASA scientists now have use of two agency-developed unmanned aerial systems that some say represent the future for drone aircraft. The drones purposely were designed for scientific investigations and offer the scientific community complementary, easy-to-use capabilities at a lower cost.
