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 ...

In order to realize the full potential of cryogenic power converters, it is vital to develop the technology for cryogenic capacitors and inductors, in order to be combined with the switching semiconductors. Capacitors with high dielectric constant and high voltage withstand at cryogenic temperatures with low weight and volume lie on the critical path. The proposed work focuses on innovative tech ...

Proposed is the technical development and design of the electronics and cooling systems for a 1 megawatt cryogenically cooled inverter suitable for use in a wide range of applications, including Uninterruptable Power Suplies (UPS) and motors in the +1000 HP range. The proposed work will provide a logical progression to the development that has already been done by American Superconductor Corp. I ...

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 ...

An innovative deep submergence low frequency, broadband transducer forefficient operation is presented. The transducer uses a multiport concept (U.S. Patent 5, 184, 332) which allows back radiation to arrive in phase with the forward radiation and allows broadband depth independent operation. Because the system utilizes Helmholtz resonators, low frequency operation can be achieved. A number of ...

Breathable release coatings that can withstand processing conditions up to 750F are needed for use on ceramic tooling. In situ removal of volatiles in solvent-based composite processing is a critical issue that will enable production of high quality parts at lower cost per part. Current release coatings meet neither the temperature nor the solvent transport requirements of solvent-based composit ...

Triton Systems, Inc will demonstrate a new method to produce a low melt viscosity PolyArylene Ether (PAE) macrocyclic oligomer that will be resin transfer molded (RTM) into optically transparent aircraft canopies. A ring opening polymerization converts the macrocyclic oligomer to an optically transparent PAE polymer with a high glass transition temperature. The PAE macrocycle is processable with ...

Current fighter canopy systems are fabricated using acrylics and polycarbonates which have low use temperatures, up to 220F and 300F, respectively. Wind tunnel testing of aircraft windshield showed that the transparency surface temperatures varied from 200F to 500F. Therefore, high Tg canopy systems are needed to fully utilize advanced weapon systems. Conventional processing techniques for high ...

Oriented composites of PZT and polymer can have properties superior to ordinary PZT as drivers for sonar transducers and hydrophones because they have a lower Poisson ratio, and a lower dielectric constant. Terfenol-D is superior to ordinary PZT because it has larger maximum strains and higher energy density, and is not subject to fatigue or depoling. For these reasons, composite Terfenol-D shou ...

SYSTRAN, and our partner Ball Aerospace and Technologies Corp. (BATC) - an experienced HLA user and member of the HLA Protofederation activity - will design and selectively demonstrate (in Phase I), and develop and significantly demonstrate (in Phase II) a series of techniques and processes that will allow users of idstributed simulations the ability to incorporate audio signatures, audio transmis ...
