The Northrop Grumman Corporation-developed Integrated Air and Missile Defense (IAMD) Battle Command System (IBCS) successfully demonstrated its ability to scale up and network across long distances during a recent U.S. Army-led test. The evaluation was conducted by U.S. Army soldiers over a five-week period with air and missile defense assets located at sites in New Mexico, Texas and Alabama.

Single Event Effects in High Altitude Aerospace Sensor Applications

There are many advantages to utilizing active electronics versus the passive systems often used in aircraft applications, such as pressure, temperature, and flow sensors. Some of these advantages are increased accuracy, reduced noise, transmission over longer signal paths, and the addition of signal conditioning. With these benefits comes the consideration that high altitude operation will expose the electronics to high-energy neutron solar particle radiation. Without proper design and component selection, this radiation may affect the reliability of measurements from aircraft sensors.

Microstructural and Mechanical Characterization of 2-D and 3-D SiC/SiNC Ceramic-Matrix Composites

The purpose of this endeavor was to investigate the effect of 3-D weave architecture on PIP-processed ceramic-matrix composites (CMC). Microstructural studies were performed to document the resulting microstructure and mechanical testing was performed to determine the high-temperature durability of the five different variants of SiC/SiNC CMC investigated.

Testing Military Vehicle Steering Systems

Military vehicles play a vital role in protecting our society — and inevitably encounter many extreme conditions across their lifespan. From the varying weight, to the rough terrain, there is a lot that can go wrong. Military steering systems must therefore be engineered to take on such extremes. This begins at the design stage and ends with analysis through testing. It's here the parts are tested to their limits and validated against the original specification and real-life requirements.

Evaluation of Peel Ply Surface Preparation of Composite Surfaces for Secondary Bonding

Lightweight composite structures offer significant long-term cost-saving opportunities for the U.S. Army as replacements for traditional metal structures. However, high-strength economical bonding processes must be developed to join composites in order for them to be viable replacements. The Army is exploring approaches, also under evaluation in the commercial aerospace industry, to reduce the process steps associated with composite bonding.

Enhanced Contacts for Inverted Metamorphic Multi-Junction Solar Cells Using Carbon Nanotube Metal Matrix Composites

In order to address issues related to mechanical and vibrational stresses that are commonly experienced in mounting, launch, and deployment of spacecraft, metal matrix composite (MMC) electrodes were fabricated with carbon nanotubes (CNTs) as reinforcement. The research plans were centered on first developing and selecting appropriate processes for fabricating CNT-MMCs based on characterization of their material properties, followed by optimizing MMC designs based on electrical testing under stress. Efforts in the program were also directed toward implementing the CNT-MMCs into solar cell device processing in a process compatible with standard clean room procedures.
