THE INNOVATIVE PROPOSED HEREIN CONCERNS THE DEVELOPMENT OF A HOLOGRAPHIC DIAGNOSTIC TECHNIQUE FOR THE MEASUREMENT OF ELECTRON DENSITY PROFILES IN THE FLOWS OVER A RV BALLISTIC RANGE MODEL. AN EXPERIMENT IS IDENTIFIED IN WHICH HOLOGRAPHIC PLASMA MEASUREMENTS WILL BE USED FOR REFINEMENT AND VALIDATION OF COMPUTATIONAL FLOW/CHEMISTRY ANALYSIS. THE TECHNICAL APPROACH IS BASED ON THE DEVELOPMENT OF A T ...

ACCELERATED SMALL SPECIMEN SCREENING TESTS FOR SCC RESISTANCE ARE NECESSARY FOR COST/TIME EFFICIENT EVALUATION OF WELD/BASE METAL FORMULATIONS IN WELD OR ALLOY DEVELOPMENT PROGRAMS AND FOR QUALITY CONTROL OF WELDED HY-130 STEELS. TEST DATA THAT IS CAPABLE OF MEASURING THE STRESS INTENSITY FOR CRACK INITIATION IN CATHODICALLY PROTECTED VESSELS IN NATURAL SEA WATER IS NECESSARY FROM DESIGN CONSIDERA ...

Maintenance and technical skills training is required to build individual proficiency within the U.S. Navy battle groups as well as many of the independent operating units. However, force reduction and budget cutbacks have resulted in the transfer oftraining responsibility for battle groups to the large deck ship and battle force commanders. With further reductions in force levels and budget on ...

THIS PROPOSAL DESCRIBES A PROGRAM TO DEVELOP A COMPACT, RUGGED, AND AUTONOMOUS PROGRAMMABLE LASER DOPPLER VELOCIMETER (LDV) FOR MARINE APPLICATIONS. THE SYSTEM WILL INCLUDE TWO MAJOR INNOVATIONS IN LDV TECHNOLOGY: A PROGRAMMABLE DIGITAL SIGNAL PROCESSOR (DSP), AND A PULSED LASER DIODE. THE DSP PROVIDES THE HIGHEST COMPUTATIONAL POWER AND PROGRAMMABILITY IN A COMPACT SIZE ALLOWING THE IMPLEMENTATIO ...

The proposed work is to develop a whole-field measurement technique that iscapable of simultaneously sizing multiple transparent droplets on a plane fromscattered light features that are independent of laser beam intensity andobscuration. Light scattered by reflection and refraction from droplets immersedin a laser sheet is recorded holographically to yield the smallest possibleprobe volume and co ...

This topic seeks a gun-hardened inertial navigator, suitable for guided munitions, made from low cost, commercially available instruments. After many years of waiting, and many failed starts, a Commercial Off The Shelf (COTS) 'Chip Gyro' is finallyemerging. Analog Devices is sampling to us integrated (all silicon) iMEMS angular rate sensor prototypes designed primarily for the high volume automo ...

For aircraft /store compatibility, a comprehensive software system requested by the Air Force for rapid assessment of flutter and ejection loads (RAFEL) poses challenging requirements. With ZAERO aeroelastic software as a base, ZONA can establish a RAFELsystem satisfying all AF's requirements. Specifically, ZONA will develop RAFEL in Phase I with: a) solution accuracy with flutter solution robustn ...

BECAUSE OF RECENTLY DEFINED TACTICAL THREATS IT IS DESIRABLE TO IMPROVE THE MANEUVERABILITY AND TAKE-OFF/LANDING ASPECTS OF AIRCRAFT PERFORMANCE. IT HAS BEEN DETERMINED THAT SUCH IMPROVEMENTS CAN BE ACCOMPLISHED BY THE USE OF THRUST REVERSERS OR VECTORED JETS. IN ORDER TO DESIGN AIRCRAFT SATISFACTORILY IT IS NECESSARY TO HAVE A PREDICTION METHOD THAT IS SUFFICIENTLY ACCURATE. THE MOST DIFFICULT FL ...

It is proposed to development of a large-scale production apparatus that produces single-walled carbon nanotubes (SWNT) and catalytic multi-walled nanotubes (MWNT) on a continuous process basis. A novel and flexible reactor design will be investigated. Theproposed reactor design will allow the control of production parameters including catalyst type and particle size, the type of carbon source, ca ...
