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 ...

A BETTER ELASTOMERIC MODIFIER WILL BE SEARCHED AND USED FOR BISMALEIMIDE (BMI) RESIN TO IMPROVE THE TOUGHNESS OF THE RESIN. THE GOAL IS GOOD ROOM TEMPERATURE TOUGHNESS WITH GOOD STRUCTURAL PERFORMANCE IN THE 350-450 DEG F RANGE. NEAT RESIN SPECIMENS AND LABORATORY SCALE GRAPHITE FIBER COMPOSITE SPECIMENS WILL BE MADE FOR TOUGHENING TESTS AND EVALUATIONS.

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 ...

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 ...

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 ...

A COMPUTER NUMERICAL CONTROLLED PROCESS FOR SPINFORMING NET SHAPE HEMISPHERES AND HEMISPHERICAL-ENDED CYLINDERS WILL BE DEVELOPED. FORTY PARTS WILL BE SPINFORMED ON EXISTING CNC CONTROLLED EQUIPMENT. IMPROVEMENT OF MECHAN ICAL PROPERTIES BY COLD WORK AND THERMAL MECHANICAL TREAT MENT WILL BE INVESTIGATED. DIMENSIONAL TOLERANCES, METALL URGICAL STRUCTURES AND MECHANICAL PROPERTIES PRODUCED BY EACH ...

N/A

ACQUISITION OF NEW ELECTRONIC SYSTEMS THAT MUST BE HARDENED FOR INITIAL NUCLEAR RADIATION (INR) REQUIRES INCREASED LEAD TIMES AND GREATER ENGINEERING AND PRODUCTION COSTS. THE CURRENT THRUST OF THE DOD IS TO PURCHASE NDI WHERE PRACTICAL. THIS STUDY ASSESSES THE FEASIBILITY AND PRACTICALITY OF INCORPORATING NUCLEAR HARDENING INTO NDI. THE STUDY WILL EXAMINE THE TYPES OF EQUIPMENT THAT ARE CANDIDATE ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...
