Vadum will implement and test a novel Nonlinear Automated Measurement System (NAMS) instrument package designed in Phase-I to perform very high dynamic range RF two-tone measurements.The NAMS will be an integrated instrument with software for performing rapid, automated linear and nonlinear large signal RF measurements.The prototype instrument utilizes an active feed-forward canceller to achieve a ...

During Phase I, the Blackhawk hanger bearing and oil cooler fan bearing applications were studied in detail, including analysis of vibration and temperature data from used oil cooler bench tests (conducted by Sikorsky) and used hanger bearing bench tests (conducted by Sentient). This data, along with an analysis of operational and environmental conditions, has allowed us to identify the probable r ...

This proposal addresses the need to further develop a robust and validated soundscape modeling tool for accurate predictions of biological, geophysical, and anthropogenic activity in CONUS and OCONUS environments. The Phase II development of the geospatial and acoustic training databases will focus on strengthening the geospatial diversity of the data by employing purposeful data collection techni ...

We propose to develop multiresolution representations and algorithms for synthetic terrain environments. They will be used for representing large terrain models as well dynamic and atmospheric simulations. Our ultimate goal is to increase the validity of the simulation by incorporating the multiple models at varying resolutions. We will use the OneSAF simulation Product Line Architecture Framework ...

The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...

Bulk InAs(x)Sb(1-x) is an infrared detector material that promises higher quantum efficiency than antimony-based superlattices in the longwave infrared (LWIR). This is due to the longer diffusion length of minority carrier holes in the bulk than in superlattices where they are localized. No native substrate exists for lattice-matched growth of InAs(x)Sb(1-x) material with LWIR bandgaps. So a key c ...

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...

Interfaces on existing military chemical/biological protection garments are not designed to fully eliminate macroscopic and microscopic air gaps at folds, fabric surfaces, or hook-and-loop closures, and thus do not provide a hermetic barrier against exposure. Creare is developing hermetic garment closure systems that seal macroscopic and microscopic gaps at interfaces and closures and provide high ...

THE PROPOSED PROJECT ADDRESSES THE REPLACEMENT OF CFC-113 (FREON) AS A CLEANING AGENT, BOTH GENERALLY AND WITH SPECIFIC ATTENTION TO THE CLEANIUG OF METALS AND COMPOSITES. THE PHASE I WORK WILL PROVIDE A COMPREHENSIVE CHARACTERIZATION OF CLEANIUG REQUIREMENTS AND KNOWN METHODS. THE APPROACH IS MULTIDISCIPLINARY ENCOMPASSING UTILIZATION OF FORCES OF VARIOUS KINDS, AS WELL AS SIMPLE REPLACEMENT OF T ...

Low cost polyurethane laminate tent materials are designed to solve the cold crack issue with PVC tent fabrics. The use of novel construction of urethane/textile laminates offers a breakthrough in environmental durability over current offerings. This new high durability laminate configuration provides for a new class of economical lightweight shelters with extended operating capability. Using a co ...
