IMAGE RECOGNITION BY OPTICAL SIGNAL PROCESSING CAN BE APPLIED TO AIR FORCE WEAPONS SYSTEMS TO CREATE "BRILLIANT MUNITIONS." THE STATE OF THE ART NOW ALLOWS REAL TIME DETECTION, DISCRIMINATION, AND TRACKING OF PREPROGRAMMED TARGETS SUCH AS TANKS, BRIDGES, AIRFIELD FEATURES, OR HIGH VALUE TARGETS. THE OBJECTIVE OF THIS PHASE I TASK WILL BE TO SHOW HOW TERMINAL HOMING BY OPTICAL RECOGNITION (THOR) CA ...

A MEMBRANE TYPE WAFER PROBE IS PROPOSED WHICH, AT THE END OF PHASE II, WILL ACHIEVE TRANSMISSION OF SIGNALS FROM TESTER TO DIE WITH LOW ABBRATIONS FOR A 100 PS RISETIME. CAPABILITIES WILL INCLUDE LOW-IMPEDANCE GROUND AND POWER CONTACTS, WITH LSI-LEVEL NUMBERS AND DENSITIES OF SIGNAL LINES. PHASE I WORK WILL DETERMINE THE DESIGN PARAMETERS NECESSARY FOR THESE GOALS THROUGH A SEQUENCE OF CALCULATION ...

GAS TURBINE AUGMENTORS HAVE HISTORICALLY EXPERIENCED DIFFICULT MAINTAINING COMBUSTION AT HIGH ALTITUDES AND LOW FLIGHT MACH NUMBERS. DUE TO THE LACK OF ANALYTICAL TOOLS, TESTING PROVIDES THE PRINCIAL MEANS OF IMPROVING A DESIGN FOR STABILITY. SUCH TESTING IS EXPENSIVE AND TIME CONSUMING, THUS ALLOWING ONLY A LIMITED NUMBER OF DESIGNS TO BE ASSESSED. WHAT IS LACKING IS A GOOD UNDERSTANDING OF THE F ...

AS YET UNIDENTIFIED PHYSICAL MECHANISMS HAVE CAUSED ABRUPT CHANGES IN THE FLIGHT PATHS OF HIGH-SPEED MISSILES WHICH HAVE LARGE LENGTHTO-DIAMETER RATIOS AND ARE RELATIVELY FLEXIBLE. THESE FLIGHT INSTABILITIES ARE PROBABLY CAUSED BY THE NONLINEAR INTERACTION OF MISSILE VIBRATION AND ROTATION, AERODYNAMIC FORCES AND THE MISSILE'S PROPULSION SYSTEM. TO REAP THE BENEFITS OF THE HIGHER AERODYNAMIC EFFIC ...

OPTICAL DESIGNS OF TWO CONCEPTS FOR WIDE FIELD, HIGH RESOLUTION PHASED ARRAY IMAGING TELESCOPES WILL BE DEVELOPED AND ANALYZED. THE RESULTS WILL THEN BE COMPARED TO FIND THE SUPERIOR CONCEPT. THE FIRST CONCEPT RESEMBLES CLOSELY THE SYSTEMS PROPOSED IN THE PAST FOR ASTRONOMICAL SPACE TELESCOPES. IT CONSISTS OF AN ARRAY OF AFOCAL SUBTELESCOPES WHOSE EXISTING BEAMS ARE OPTICALLY COMBINED TO FORM A UN ...

DESIGN AND PRODUCE FUNCTIONAL PROTOTYPE OF A SMALL SELF-CONTAINED ACOUSTIC SIGNAL SOURCE TO BE DEPLOYED AT SEA, WHICH WILL INJECT AN OPERATOR-SELECTED PULSE TRAIN AT SOURCE LEVEL AT 225 DBRE LU PA INTO THE WATER AT DEPTHS PRESELECTED FROM 100 TO 1500 FEET. PULSE TRAIN ACCURACY SHALL BE BETTER THAN 50 MILLISECONDS; PULSE DURATION SHALL BE LESS THAN 250 MILLISECONDS. A MULTI-REDUNDANT SAFETY AND ARM ...

PERSONNEL WORKING IN EXTREME ENVIRONMENTS OR WEARING BALLISTIC AND/OR NUCLEAR/BIOLOGICAL/CHEMICAL (NBC) PROTECTIVE CLOTHING ARE SUBJECT TO THE HAZARDS OF OVERHEATING. THESE HAZARDS INCLUDE PHYSICAL DISCOMFORT, DECREASED PHYSICAL AND MENTAL ABILITIES, DEHYDRATION, AND EVENTUALLY DEATH FROM HEAT STRESS. THE NUMBER OF PERSONNEL VULNERABLE TO THESE HAZARDS IS ALREADY QUITE LARGE AND IS STEADILY INCREA ...
