Not Available The demand for high data rate (HDR) very small aperture terminal (VSAT) networks has been increasing in the last two years. Newer network applications require a minimum of T1 data rate (1.544 Mbps). The network must also be robust for the operating conditions of VSATs- small diameter dishes with inaccurate tracking and a cluttered terrain environment. Most commercial VSAT modems sup ...

the proposed Phase I SBIR program will demonstrate the production of diamond- and graphite fiber-reinforced aluminum and copper matrix composites for use in thermal management systems. Specifically, Powdermet will produce interface-controlled diamnd and graphite (DKDX milled fiber) reinforced aluminum and copper composites, and evaluate their application to battery tubes, structural radiators (and ...

Replacement of Be components is high on every BMDO contractors agenda. Not only will replacing Be reduce liability, it will also reduce component cost and quite possibly weight. In this Phase I SBIR Powdermet will investigate light weight compositematerials to replace Be. Phase II of the program will involve optimizing the process and control of the composite replacement and final componeent fa ...

Light weight structures are improtant for many DoD applications. Currentresearch on Carbon/carbon at temerpatrues below 1200 F have been margiallysuccessful. More research is mneeded on identifying other methods for protectionof the carbon over this temperature range. The team of PSU and Powdermet will eexplore several unique methods for carbon/carbon protection. High temperature structures can ...

This Phase I SBIR program will demonstrate the production of high temperature,high saturation inductance magnet materials and power converter circuit designsfor directed energy laser power supplies. Powdermet will manufacture and characterizea series of articicially structured metallic magnets with controllable permeabilitiesand low losses at 300 C. These insulating ferromagnetic heterostructure ...

70789 There are no low cost solutions to the problem of neutron radiation in nuclear power plants. Current protective materials and techniques for making them are very expensive. Recent research investigating Ni/boron carbide material, fabricated via high velocity oxygen fuel (HVOF) plasma spray, has shown significant positive results in protection from neutron radiation. This projec ...

This Small Business Innovation Research Phase I project will enable a 2-fold increase in conductivity for products without sacrificing power or capability. Recently, a new high thermal conductivity material has been produced using CVD fluid bed coating process and low cost consolidation techniques. The realization of improved electronic substrates is dependent on the increases in thermal conductiv ...
