Laser Guided Rocket System

Arnold Defense
St. Louis, MO

Arnold Defense, the St Louis based international manufacturer and supplier of 2.75-inch rocket launchers, recently announced the commencement of initial low-rate production of their “FLETCHER” land-based, 2.75-inch/70 mm weapon system. The FLETCHER system can just as easily be mounted on military vehicles as well as base defense platforms.

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.

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.

Reusable Rapid Prototyped Blunt-Impact Simulator

Rapid prototyping (RP) is the term most commonly used to describe additive manufacturing technologies. An additive manufacturing technology is any manufacturing process that fabricates a part by adding one layer of material at a time, one on top of the other, to produce detailed 3-D geometries directly from 3-D computer-aided design (CAD) models.

Ducted Fans for Aircraft Propulsion

One alternative aircraft propulsion technology being explored is an array of electrically powered ducted fans distributed across the wing span or integrated into the wing. Researchers are studying the cross-communication – or cross coupling – between the aircraft engine’s RPM and the airflow characteristics about the airplane wing.

Electronic Warfare Creates Battlefield on a Different Wavelength

Soldiers on the ground are now capable of rapidly reacting to electronic and cyber data rather than waiting on their higher echelons. Soldiers assigned to Headquarters and Headquarters Company, 1st Armored Brigade Combat Team, 1st Cavalry Division, currently deployed in Poland, are among the first brigades supporting Atlantic Resolve to train on a new system that enables a team to forward deploy and respond to enemy frequencies using new electronic warfare (EW) technology.

Sandia Delivers First DOE Sounding Rocket Program Since 1990s

A new rocket program could help cut research and development time for new weapons systems from as many as 15 years to less than five. Sandia National Laboratories developed the new program, called the High Operational Tempo Sounding Rocket Program (HOT SHOT), and integrated it for its first launch earlier this year under the National Nuclear Security Administration’s direction.
