THE RAM ACCELERATOR IS A RAMJET-IN-TUBE CONCEPT FOR ACCELERATING PROJECTILES TO A VERY HIGH VELOCITIES. IT USES PROPULSIVE CYCLE SIMILAR TO THAT OF A CONVENTIONAL RAMJET. THE RAM ACCELERATOR CAN OPERATE IN SEVERAL REGIONS: THERMALLY CHOCKED SUBSONIC, AND TWO OBLIQUE DETONATION MODES. THE IGNITION OF THE FUEL/OXIDATION MOISTURE IS ACHIEVED BY FORCING THE MIXTURE THOUGH A SENES OF SHOCKWAVES THAT IN ...

THE PROPOSED PHASE I PROGRAM WILL DEMONSTRATE A COMPOSITE AIRCRAFT GENERATOR HOUSING, OR RESONANT CONVERTOR, WHICH WILL BE LIGHTER, STRONGER, STIFFER AND HAVE ENHANCED THERMAL MANAGEMENT PERFORMANCE THAN THE CURRENT ALUMINUM COMPONENT. IN PHASE I, SPARTA ENGINEERS, WORKING WITH A REPRESENTATIVE AIRCRAFT GENERATOR MANUFACTURER (I.E., LELAND ELECTROSYSTEMS, INC) WILL DEVELOP AN ADVANCED COMPOSITE GE ...

DELAY LINES FABRICATED FROM HIGH-TEMPERATURE SUPERCONDUCTORS PROMISE BETTER PERFORMANCE WITH MUCH LOWER WEIGHT, VOLUME, POWER, AND COST REQUIREMENTS THAN CONVENTIONAL TECHNOLOGIES. WE PROPOSE TO FABRICATE AND MEASURE THE WIDE-BAND DISPERSION, LOSS, AND POWER-DEPENDENT CHARACTERISTICS OF A SUPERCONDUCTING DELAY LINE IN THE 6GHZ TO 18GHZ FREQUENCY RANGE FOR USE IN HIGH PERFORMANCE ELECTRONIC WARFARE ...

THE ADVANTAGES OF HIGH TEMPERATURE SUPERCONDUCTORS COULD BE WIDELY UTILIZED IN EW SYSTEMS IF A LOW LOSS, HIGH-DYNAMIC RANGE SWITCH, COMPATIBLE WITH THE CRYOGENIC ENVIRONMENT COULD BE DEMONSTRATED. GAAS FET SWITCHES AND PIN DIODE SWITCHES ARE THE MAIN SWITCH TECHNOLOGIES USED IN MICROWAVE CIRCUITS, BUT NEITHER TYPE IS OPTIMUM FOR USE WITH HTS DEVICES. STI HAS PROPOSED AN INNOVATIVE THREE TERMINAL D ...

THE EARLY ACQUISITION SUPPORT ESTIMATOR (EASE) IS AN IBM PC-BASED DECISION SUPPORT SYSTEM FOR PRE-MILESTONE I ACQUISITION DECISION MAKING. IT PROVIDES LIFE CYCLE COST (LCC) INFORMATION CONCERNING THE LOGISTIC DESIGN OPTIONS THAT MAY BE INCLUDED IN A WEAPON SYSTEM DESIGN. THE TOOL IS DESIGNED TO PROVIDE A USER-FRIENDLY INTERFACE THAT WILL FACILITATE LOW DATA INPUT TIME AND ALSO PROVIDE EASY-TO-INTE ...

THIS PROPOSAL RESPONDS TO THE USAF'S STATED NEED FOR RESEARCH TO DEVELOP A CORROSION DETECTION TECHNIQUE WHICH CAN DETECT THE ONSET OF CORROSION AND TO DEVELOP A FATIGUE LIFE ANALYSIS CAPABILITY WHICH ACCOUNTS FOR CORROSION EFFECTS. THE PROPOSED METHODOLOGY IS TO DEVELOP CORROSION KINETIC EQUATIONS WHICH CAN PREDICT THE ONSET AND PROGRESS OF CORROSION WITH HIGH CONFIDENCE, DEVELOP AN IMPROVED CORR ...

THE ACCURATE MEASUREMENT OF ELECTROMAGNETIC FIELDS IS OFTEN COMPLICATED BY THE INTERACTION BETWEEN THE FIELD BEING MEASURED AND THE RECEIVING ANTENNA WITH ITS ASSOCIATED ELECTRONICS AND CABLING. WITH THE DEVELOPMENT OF HIGH FREQUENCY FIBER OPTIC ANALOG LINKS, OPTICAL CABLES HAVE BEEN USED TO ISOLATE THE MEASUREMENT ANTENNA. HOWEVER, PREVIOUS EFFORTS HAVE HAD THE DISADVANTAGE OF REQUIRING A RELATIV ...
