This Phase I research is intended to evaluate the feasibility of manufacturing low-cost, acid-resistant sanitary sewer pipe from sulfur concrete. Sulfur is an abundant mineral recovered from coking, natural gas processing, and petroleum refining. Secondary recovery of sulfur, resulting from environmental regulation, produces more material than is needed by U.S. industry. The U.S. Bureau of Mines ...

This proposal describes the development of an instrument based on laser-induced breakdown spectroscopy (LIBS) for the detection of lead in paint and soil that will have both military and commercial applications. The Phase I instrument will be similar to multi-species, portable LIBS instruments built by Dr. David Cremers at Los Alamos National Laboratory that utilize a spectrograph/charge coupled ...

The objective of the proposed project is to develop innovative new analytical instrumentation and methodology capable of performing fully automated, non-destructive analysis of semiconductor sensor elements and arrays locate on three inch diameter wafers. The instrumentation would be capable of analyzing II-VI compounds and alloys, particularly HgCdTe. The methodology would employ state-of-the-a ...

ANR technologies have been successfully incorporated in communication headsets to improve speech intelligibility and hearing conservation in high noise environments. This Phase I research effort will introduce advancements in optimal controller/headset architectures that will lead to: greater SPL attenuations at the ear, significantly extended ANR bandwidth, and improvements in speech intelligibi ...

Automated Cynamics Corporations (ADC) proposes to exploit its knowledge of automated in-situ consolidation of thermoplastic carbon fiber unidirectional tape to reduce the high scrap rate currently experienced in the in the fabrication of thermoset (epoxy) carbon fiber sabots. The current production process requires several steps which result in material loss (scrap) of approximately 60-70%. App ...

The complex HEV power systems necessitates flexible and dynamic simulation software providing tools for evaluating, characterizing and optimizing these systems. Existing software have neglected to characterize significant component data such as heat loads, cabin cooling requirements, battery thermal management, and heat rejection. Vehicle performance (accounting for environmental conditions and s ...

We propose to develo a numerically efficient rotorcraft trim and transient response algorithm. The algorithm is intended for application in a periodic dynamic system with a large number of degrees of freedom as is commonly the case in current comprehensive rotorcraft analysis codes (such as 2GCHAS). The innovation of this proposal can be summarized as follows: 1) Utilizing Model Order Reduction ...

The proposed work in phase I will address the problem of establishing the feasibility of a new approach for developing a system to be used with military land vehicles for the on-board recovery and purification of water. The system will ultimately generate 15 gallons of potable water per day. The aims are to produce a lightweight, compact, robust, reliable, and energy efficient unit that requires ...

Current and future Army helicopter missions require close support of combat operations, resulting in exposure to enemy ground fire. Current armor systems significantly reduce the load carrying capacity of the helicopter thereby reducing its mission effectiveness. New innovative technologies to significantly reduce the areal density of armor is needed to make significant enhancements to survivabili ...
