THE U.S. AIR FORCE HAS A NEED TO DEVELOP A GREATER CAPABILITY OF ANALYZING MUNITIONS/ARMAMENT INTERACTIONS. IT IS PROPOSED THAT THE "HULL CODE" BE MODIFIED IN A WAY THAT WILL SIGNIFICANTLY IMPROVE ITS ABILITY TO DO THIS. THE IMPLEMENTATION OF VARIOUS NUMERIC IMPROVEMENTS WILL BE ACCOMPLISHED AND A TWO DIMENSIONAL PROOF OF CONCEPT TEST WILL BE CONDUCTED.

THE DEPARTMENT OF TRANSPORTATION (DOT) IS REQUIRED TO MAIN- TAIN THE NATION'S BRIDGES AND ENSURE THEIR SAFETY. HOWEVER,A LARGE NUMBER OF BRIDGES HAVE NOT BEEN RECENTLY INSPECTED TO DETERMINE IF THEY ARE CAPABLE OF SAFELY SUPPORTING THE TRAFFIC THAT IS CROSSING THEM. THE CURRENT METHOD OF SURVEYING BRIDGES, TO DETERMINE THEIR STRESS CONDITION, IS COSTLY AND TIME-CONSUMING. THIS PROGRAM WILL DEVELOP ...

MICROWAVE COUPLING SIMUATION CODES (MCCS) ARE REQUIRED FOR MODELING SUSCEPTIBILITY OF MILITARY SYSTEMS TO HIGH POWER MICROWAVES (HPM). MCCS ASSIST IN DETECTION OF SYSTEM WEAKNESSES TO HPM AND IN EVALUATING PROPOSED HPM-HARDENING TECHNOLOGY. THE RAPIDLY INCREASING NEED TO ESTABLISH SYSTEM SUSCEPTIBILITIES TO HPM MANDATES DEVELOPMENT AND DISTRIBUTIONN OF MCC SOFTWARE WHICH MAY BE OPERATED BY SYSTEM- ...

CURRENT METHODS USED TO MEASURE STRAIN AT HIGH TEMPERATURES DEPEND ON UNDESIRABLE ATTACHMENTS, EXTENSIONS, OR INDENTATIONS OF THE TEST SAMPLES. THIS STUDY WILL INVESTIGATE THE USE OF NEW TECHNOLOGY TO APPLY HIGH TEMPERATURE COATING MARKS TO TEST SAMPLES. THESE APPLIED MARKS WILL ACT AS A REFERENCE OR GAUGE FOR OPTICAL STRAIN MEASUREMENT. MATERIALS INCLUDING REFRACTORY METALS AND CERAMICS WILL BE A ...

POLYMERIC OR CERAMIC INSULATORS CONVENTIONALLY ARE BEING USED IN HIGH VOLTAGE PULSED SYSTEMS. NEW APPROACHES ARE NEEDED THAT WOULD REDUCE INSULATORS RING THICKNESSES AND INCREASE CORRESPONDING GRADING RINGS FLASHOVER VOLTAGE. SUCH AN APPROACH WOULD POSSESS IN COMPARISON TO CONVENTIONAL INSULATORS: HIGHER SURFACE FLASHOVER FIELD STRENGTH; SMALLER PHYSICAL DIMENSIONS FOR EQUIVALENT VOLTAGE HOLDOFF; ...

THE DEVELOPMENT OF HIGH POWER, LOW IMPEDANCE, LIGHTWEIGHT ENERGY STORAGE TRANSMISSION LINES FOR PULSE-POWER APPLICATIONS IS CRUCIAL FORSMALLER, LIGHTWEIGHT, SPACE-BASED, PULSE-POWER SYSTEMS. DEVELOPMENT OF HIGH DIELECTRIC ENERGY STORAGE LINE TECHNOLOGY WOULD GREATLY REDUCETHE SIZE, WEIGHT, AND COMPLEXITY OF PULSE POWER SYSTEMS UTILIZING THESE TYPES OF COMPONENTS. EFFICIENT TRANSPORT OF 400KV, 100K ...

CURRENT DESIGNS OF AIR FORCE HARD TARGET PENETRATING WEAPONS PLACE THE FUZE WELL IN THE TAIL OF THE WEAPON. THIS LOCATION CAUSES SOME DIFFICULTY FOR A SMART FUZE ALGORITHM TO DISCRIMINATE BETWEEN FLEXIBLE BODY WEAPON RESPONSE AND THE LOADING EFFECTS CAUSED BY THE PENETRATION OF SOIL OR CONCRETE. THE AFT LOCATION ALSO LEADS TO CATASTROPHIC FUZE FAILURE WHEN THE WEAPON EXPERIENCES A "TAIL SLAP." CHA ...

THE PRIMARY TECHNIQUES FOR CONDUCTING VULNERABILITY ANALYSES OF MOBILE OR FIXED TARGETS ARE (1) PROBABILISTIC STUDIES USING SIMPLIFIED METHODOLOGIES TO MODEL THE ENTIRE SYSTEM OR PROBLEM AND (2) FIRST PRINCIPLES FINITE ELEMENT OR HYDROCODE CALCULATIONS THAT MODEL DETAILED PHYSICAL INTERACTIONS AND STUDY A SPECIFIC PROBLEM OR PORTION OF A PROBLEM. BOTH TYPES OF ANALYSES REQUIRE A DETAILED TARGET MO ...

ADVANCED ENGINE TECHNOLOGY AND HYPERSONIC FLIGHT SPEEDS OF FUTURE MILITARY AIRCRAFTS PLACE INCREASING HEAT LOAD ON JET FUELS. THE INCREASE IN HEAT LOAD PUSH THE OPERATION OF FUELS INTO THEIR SUPERCRITICAL REGIME. THE PERFORMANCE OF FUTURE AIRCRAFT WILL BE SERIOUSLY LIMITED IF FUELS CANNOT BE OPERATED EFFECTIVELY AT SUPERCRITICAL CONDITIONS. THE PRECOMBUSTION CHEMISTRY AND TRANSPORT PROCESSES AT TH ...
