Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

THE NEED EXISTS FOR AN EFFICIENT HYPERSONIC INLET FLOW ANALYSIS CODE THAT WILL CALCULATE BOTH EXTERNAL AND INTERNAL FLOW FIELDS INCLUDING VISCUS EFFECTS. THE FIRST OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP A PROTOTYPE CODE BADED ON A PARABOLIZED NAVIER STOKES FORMULATION WITH A 3D PRESSURE EQUATION INCORPORATED IN REGIONS HAVING STRONG STREAMWISE ELLIPTIC EFFECTS. THE SECOND OBJECTIVE IS TO D ...

Recent trends in submarine design indicate the need for-locating more electrical components, such as propulsion motors and actuators, outside the pressure hull. As a result, there is a need for electrical hull penetrators/connectors which can transfer high currents or high voltages through the submarine's pressure hull. We propose to review the capabilities and limitations of existing penetrator/ ...

Enemy forces can be crippled quickly at the beginning of a war by separating the enemies command and control structure from its combat forces and other elements of its defensive network. A false target generator has the potential to saturate or tie up an enemies air defense net and increase survivability of our own airborne assets. An unmanned aerial vehicle (UAV) is an optimum candidate for a dec ...

HIGH-PRESSURE WATERJET IS ONE OF SEVERAL NEW METHODS FOR CUTTING MATERIALS DEVELOPED DURING THE LAST DECADE. CURRENTLY IT IS USED, AT STATIC WATER PRESSURE UP TO 60,000 PSI, TO CUT A WIDE VARIETY OF SOFT AND MEDIUM-HARD MATERIALS IN FACTORIES; IT HAS BEEN EVALUATED FOR GEOTECHNICAL APPLICATIONS WITH VERY LIMITED SUCCESS. THIS RESEARCH CONCERNS THE USE OF ABRASIVE-ENTRAINED WATERJET FOR CUTTING AND ...

Broadband signal processing is important for interpreting signals received from active sonar transmissions. The traditional approach to processing broadband signals in the sonar literature is to assume a harrowband condition that Justifies the use of narrowband signal processing. RTcently there has been renewed interest in avoiding the narrowband assumption and in actually using techniques th ...
