The goal of this program is to design and fabricate selected liquid rocket engine combustion components. This goal will be accomplished by developing a low-cost, near net-shape technology for fabrication and rapid densification of ablation and oxidation-resistant LRE components for a wide variety of Air Force missions. The material which will be used for this purpose is zirconium diboride/boron ...

Significant similarities exist between DoD simulation applications and networked simulation games developed for entertainment. To date, however, there has been no compelling reason for commercial game developers to adopt DoD methods and standards. Interestingly, HLA compares favorably to current commercial solutions like Microsoft's DirectPlay. There is clear benefit to DoD if HLA is embraced b ...

The final prototype of the Microcircuit Board Repair apparatus will be capable of laying down or lifting metal strips with micrometer dimensions. Under real time computer control, the translation stages will be fully automated or manually controlled. The end user will monitor the process in real time using a camera attached with the source. Laying down the metal lines will be done using Laser C ...

Development is proposed of a new, rotary form of Stirling cryocooler which offers longer operating life and much lower vibration than reciprocating forms of cryocoolers. The proposed machine has fewer moving parts to wear and can be completely balanced to eliminate vibration in all planes by simple counterweights on the shaft, which is not possible in reciprocating machines. The rotary desi ...

THIS WORK IS TO DEVELOP A METHOD TO IMPROVE THE ABILITY OF THE USNRC TO EVALUATE THE OPERATIONAL SAFETY SIGNIFICANCE OF OCCURANCES AT NUCLEAR POWER PLANTS. PERHAPS THE AREA OF GREATEST SAFETY SIGNIFICANCE IS HUMAN PERFORMANCE, BUT THE TECHNIQUES USED BY NRC DO NOT EVALUATE HUMAN PERFORMANCE IN ANY SYSTEMIC WAY. THE WORK IS PROPOSED TO BE PERFORMED IN THREE STAGES, AND BUILDS ON METHODS THAT HAVE B ...

Resin Transfer Molding (RTM) offers the opportunity for significant cost savings in the fabrication of polymer matrix composite structures. However, the realization of this cost savings has been limited to lower temperature (e.g. epoxy) matrix composites. The main reason for this has been that available high temperature (e.g. polymide) composites have not possessed the characteristics which make ...

The objective of this proposal is to design and manufacture a hybrid battery between Moltech Corporation cells, which provide long cycle life , high specific energy (300-400 Wh/Kg) and high energy density (300-400 Wh/Kg), with either a high rate lead acid battery or a supercapacitator, which will provide extremely high discharge rate capabilities. The Moltech cell will continuously keep the Pb-H o ...

Acoustic transducers have found wide applications ranging from Navy sonar systems to civilian underwater imaging. Piezoelectric materials perform an essential role of electromechanical energy conversion in such devices. Current piezoelectric materials can not satisfy the increasing requirement of the sensitivities of acoustic transducers for both military and civillian applications. This progra ...

The concerted effort to digitize the battlefield via digital wireless communications translates these data transfer requirements to the handset since transceivers can now serve as network nodes. Therefore a primary ingredient to satisfying the digital wireless network demand lies in securing dramatic improvements in transmitter efficiency. Many radios include the capability to dynamically adjust ...
