AN AGGRESSIVE ARCJET CONFIGURATION OPTIMIZATION PROGRAM IS PROPOSED TO DESIGN A HIGH PERFORMANCE, VARIABLE POWER AMMONIA ARCJET. A NOVEL TEST BED ARCJET AND MODULAR NOZZLE DESIGN APPROACH IS PROPOSED TO ALLOW LOW COST OPERATION AND TEST EVALUATION OF EXOTIC ARCJET NOZZLE CONFIGURATIONS. SIMPLE, BUT MEANINGFUL ARCJET PLUME DIAGNOSTICS ARE PROPOSED TO UNAMBIGUOUSLY IDENTIFY KEY VARIABLE POWER ARCJET ...

CONVENTIONAL TWO-DIMENSIOANL INTEGRATED CIRCUITS DESPITE THEIR CONSPICUOUS PROGRESS IN SUBMICRON DOMAIN HAVE ALMOST REACHED THEIR LIMITS IN PACKING DENSITY. ONE WAY TO ACHIEVE A HIGH LEVEL OF INTEGRATION IS TO STACK THE CIRCUIT LAYERS VERTICALLY TO RESULT IN A THREE-DIMENSIOANL CHIP SYSTEM ELECTRO-OPTEK PROPOSED TO DEVELOP AN INNOVATIVE THREE-DIMENSIONAL CHIP CONNECTION SYSTEM FOR FABRICATING HYPE ...

WE PROPOSE TO DEVELOP ULTRA RADIATION-HARD COMPLEMENTARY HETEROJUNCTION BIPOLAR TRANSISTOR (CHBT) CIRCUITS FOR HIGH FREQUENCY APPLICATIONS SUITABLE FOR DENSE SPACEBORNE SYSTEMS. WE WILL DEVELOP A SELF-ALIGNED BASE OHMIC METAL (SABM) PROCESS WITH THIN BASE STRUCTURES TO ACHIEVE VERY HIGH CUT-OFF FREQUENCIES CLOSE TO 80 GHZ. WE WILL OPTIMIZE THE PERFORMANCE OF N-P-N AND P-N-P DEVICES ON THE SAME CHI ...

THERMAL CONTROL IS A DESIGN DRIVER FOR SPACE APPLICATIONS OF NI-H2 BATTERY SYSTEMS. COMPARED WITH THE NI-CD BATTERIES THEY ARE REPLACING, THE NI-H2 BATTERIES REQUIRE LOWER OPERATING TEMPERATURES AND GENERATE HIGHER HEAT LOADS THAT INCREASE COOLING NEEDS. THE SPACE RADIATORS USED FOR COOLING ARE GENERALLY SIZED FOR THE PEAK HEAT LOADS DURING BATTERY DISCHARGE TO AVOID EXCESSIVELY HIGH TEMPERATURES ...

A NEW APPROACH TO HIGH PERFORMANCE ICBM DESIGN HAS BEEN IDENTIFIED. THE END PRODUCT IS A HIGHLY STABLE, LOW DRAG, TWO-STAGE BOOSTER WHICH IS LIGHTER, FASTER BURNING, MORE RELIABLE, AND LESS EXPENSIVE THAN AN EQUIVALENT, CONVENTIONAL, THREE-STAGE MISSILE. MAJOR PERFORMANCE IMPROVEMENTS ARE OBTAINED BY REPLACING THE TRADITIONAL, CYLINDRICAL UPPER MOTOR STAGES AND POST-BOOST VEHICLE (PBV) WITH A SING ...

A RESEARCH PROGRAM IS PROPOSED TO DEMONSTRATE THE FEASIBILITY OF A COMPANY PROPRIETARY LIGHTWEIGHT, COMPACT SOUND SOURCE CONCEPT TO GENERATE THE HIGH INTENSITY, HIGH FREQUENCY CONTROLLED SOUND PRESSURES REQUIRED IN EXPERIMENTAL INVESTIGATIONS OF COMBUSTION INSTABILITY IN LIQUID ROCKET ENGINES. THE PROPOSED WORK PLAN IS DIVIDED INTO THREE PRINCIPAL PARTS. THE FIRST IS TO SELECT THE MOST PROMISING D ...

HNC HAS DEVELOPED AN AUTOMATED MECHANISM FOR INDEXING AND RETRIEVING FREE TEXT DOCUMENTS CALLED DOCUMENT RETNEVAL USING MEANING (DKUM). DRUM IS BASED ON CONTEXT VECTORS THAT ENCODE A REPRESENTATION OF THE MEANING OF DOCUMENTS. THIS HNC PROPRIETARY APPROACH WAS CHOSEN FOR FUNDING BY DARPA AS PM OF THE TIPSTEK TEXT DETECTION AND EXTRACTION PROGRAM. DRUM IS ABLE TO: * PERFORM FREE TEXT DATABASE DOCUM ...
