Improved head and hearing protection is required for aircraft maintainers working on a carrier flight deck during launch and recovery operations. The current head protection is inadequate in many aspects including impact protection, hearing protection, cleaning, comfort, and compatibility with night vision goggles (NVGs) and with chemical, biological, and radiological (CBR) equipment. Creare pro ...

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 ...

Lithium oxyhalide batteries offer energy densities several times higher than thermal batteries. Like thermal batteries, lithium oxyhalide batteries have unactivated storage lives in excess of 20 years and are mechanically rugged. Some of the main advantages that lithium oxyhalide batteries offer are flat discharge voltage profiles and potentially long operating lives. However, battery performanc ...

Advanced space-borne infrared detectors require cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at 10 K, with additional loads at higher temperatures. A multistage cooler, capable of cooling multiple loads, will offer large potential gains in system efficiency and weight. Turbomachine-based Brayton cryocoolers are ideal candidates for these m ...

The projected cost for the Mentis Sciences, Inc., (MSI) prototype PAC3 radome is 1/6th of the total cost of the present system. A Pareto analysis of the current MSI process indicates that the two largest costs in radome production are the direct labor associated with fabrication and the cost of the raw materials. In Phase I MSI demonstrated that COTS paint spraying technology reduced the direct ...

Power generation, power distribution and electric propulsion on ships and aerospace vehicles could be made smaller, lighter, more efficient, more versatile, and lower maintenance by operating these systems—partly or entirely—at cryogenic temperatures. Our goal is to demonstrate the advantages of cryogenic operation in regard to electronic components, specifically semiconductor devices (power d ...

Solid State Scientific Corporation proposes an triangular barrier photodiode (TBPD) detector for use on a dual mode sensor. The TBPD will function as a passive low-light visible-SWIR imager at long range and as a 3-D LADAR sensor at short range. The TBPD has the advantage of increased optical gain with decreased incident power, making it very attractive for applications with weak target signals, ...

The objective of this program is to develop a wide field of view spectral imaging sensor to support theater surveillance and intelligence. The AHS operates in the Mid Wave Infrared (MWIR) band and provides day/night spectral target cueing, geolocation and identification of hot battlefield threats. Currently deployed EO sensors can measure broadband MWIR signals, but are incapable of providing adva ...

Provision of clean drinking water poses a significant challenge to Army units in the field. Due to the quantity of water required and its substantial weight, soldiers can only carry a limited supply, and sustainment of soldiers through centralized resupply poses major logistical hurdles in many situations. Existing portable water filters to not meet the need to treat locally available water supp ...

75655S The photovoltaics (PV) industry is having difficulty finding enough raw materials to match its rapid growth. In addition, traditional sources of secondary grade polysilicon are no longer readily available at inexpensive prices. Reducing the cost of solar silicon wafers is the key to lowering the price of crystalline silicon solar cells. This project will develop a single-step wafer fabr ...
