The Acoustech Corporation as the prime contractor and the Pennsylvania State University - Applied Research Labc-atory as the subcontractor propose to design, manufacture, and test an underwater acoustic intensity probe containing a geophone and two-hydrophones encased in a neutrally buoyant package. The results of this proposed effort are anticipated to be highly successful since the researc ...

Currently, most antenna array designs are mechanically steered. However, as demand for higher performance antennas increases, an electronic replacement for the mechanical system becomes necessary. An alternative that may prove to be more cost effective is to use ferrite patch antennas as the elements in the array. The antenna's radiation characteristics are controlled by the direction and magni ...

Unusually active nanosize metal powders have been in development and production in Russia since 1975, and they are now being manufactured in the United States. Their size, approximately 50 to 100 nanometers, provides promise for sub-micron size features. The powders have significant stored energy so that they can exotherm well below melting with enough energy to cause them to melt. They are usua ...

BONN Corporation (BONN) has chosen to concentrate on a methodology that computes an optimal target search in near-real-time, with the capability of accommodating user-definable optimality based upon time / pathlength, probability of target detection target value, and survivability in a dense threat environment. This methodology will be extensible to address multiple airborne platforms and multipl ...

A key problem associated with aircraft turboshaft engines is the need to provide adequate cooling for the combustor liner. The general approach which has been taken toward this problem is to utilize a portion of incoming combustor air for film-cooling of the liner. This proposal deals with a cooling technique for combustor liners which does not utilize film cooling. Instead, a special liner des ...
