ATOMIC OXYGEN-INDUCED DEGRADATION OF MATERIALS IN LOW EARTH ORBIT IS A PROBLEM OF GREAT CONCERN IN THE DEPLOYMENT OF SATELLITES, REFLECTORS AND MIRROR AND ANTENNA STRUCTURES. IN PARTICULAR, THE DEGRADATION OF THIN CARBON-CARBON COMPOSITE MATERIALS BY ATOMIC OXYGEN RESTRICTS THE OPERATIONAL LIFE AND BATTLE-READINESS OF THIS OTHERWISE STRUCTURALLY ADVANTAGEOUS MATERIAL. ALTHOUGH SEVERAL METHODS ARE ...

FERROELECTRIC THIN FILM DEVICES OFFER A NUMBER OF ADVANTAGES FOR USE AS COMPUTER MEMORIES, INCLUDING HIGH BIT-DENSITY, NONVOLATILE LOWVOLTAGE OPERATION OVER A WIDE TEMPERATURE RANGE, SHORT ACCESS AND CYCLE TIMES, AND RELATIVELY HIGH RADIATION HARDNESS. TO RESPOND TO THE NEED OF DESIGNIING AND DEVELOPING LIGHTWEIGHT, RADIATION HARD, HIGH PERFORMANCE ELECTRONIC CIRCUITS FOR USE IN INTERCEPTORS, ACTI ...

THE ARES CORPORATION HAS TEAMED WITH THE CALIFORNIA MUNITIONS DEVELOPMENT CORPORATION (CAMDEC) TO PROPOSE AN INNOVATIVE CONCEPT FOR IMPROVING THE FIDELITY AND FLEXIBILITY OF HE NUCLEAR EFFECTS SIMULATION. THIS CONCEPT OFFERS A SIMPLE, LOW COST, UNIFORM, AND HOMOGENEOUS TEST CHARGE THROUGH THE USE OF A CONSUMABLE CONTAINER, WHICH ITSELF TAKES PART IN THE DETONATION PROCESS ELIMINATING CONTAINER DEB ...

PRESENT HF AIRCRAFT COMMUNICATIONS ARE BURDENED WITH INEFFICIENT, NARROW BANDWIDTH, SLOWLY TUNED HIGH POWER COUPLERS. THE ASTRON PROPOSED AIRCRAFT ANTENNA SYSTEM IS AN EASILY ADDED, CONFORMAL ANTENNA WHICH OBVIATES THE ABOVE DISADVANTAGES BY ELIMINATING THE COUPLER. FURTHER, IT LENDS ITSELF TO USING 2 SUCH ANTENNAS WHICH CAN OPERATE IN A TRANSMIT/TRANSMIT AND TRANSMIT/RECEIVER SIMULTANEOUS OPERATI ...

AN INNOVATIVE SINGLE ANTENNA ARRAY IS PROPOSED WHICH CAN ACHIEVE EXTREMELY HIGH DIRECTION OF ARRIVAL ACCURACY FOR PULSE SORTING APPLICATIONS. THE MAXIMUM DIAMETER IS LESS THAN 4 INCHES AND CAN BE MADE FLUSH MOUNTING.

AN ADVANCED TECHNIQUE IN THE ATOMIZATION OF LIQUIDS WILL BE UTILIZED IN DEVELOPING AN AEROSOL GENERATOR TO SATISFY THE REQUIREMENTS OF THIS PROJECT. THE PHASE I AEROSOL GENERATOR WILL BE CAPABLE OF OPERATING AT RELATIVELY LOW AIR PRESSURES, TO INSURE HIGH VIABILITY AFTER AEROSOLIZATION. THE SYSTEM WILL BE ESSENTIALLY NON CLOGGING AND WILL BE INSENSITIVE TO PARTICULATE MATTER IN THE LIQUID.

GROUND RADARS AND OTHER SPACECRAFT SUPPORT SYSTEMS WHICH TRANSMIT MICROWAVE RADIATION MAY PRODUCE ELECTRIC FIELD STRENGTHS IN EXCESS OF THOSE SPECIFIED IN MIL-STD-461. THESE HIGH ELECTRIC FIELD STRENGTHS CAN DAMAGE OR REDUCE THE RELIABILITY OF SPACECRAFT AND ELECTRONIC SYSTEMS BEFORE AND DURING LAUNCH. A HIGH POWER MICROWAVE DETECTOR (HPMD) WILL BE DEVELOPED TO DETECT ELECTRIC FIELDS OVER THE 1 TO ...

THE NAVY-S ASW DETECTION AND CLASSIFICATION SYSTEMS ARE DEPENDING INCREASINGLY ON THE USE OF TOWED RECEIVING ARRAYS BECAUSE THEY PROVIDETHE OPPORTUNITY TO OBTAIN A LARGER MOBILE RECEIVE APERTURE WITH LESSFLOW NOISE THAN OCCURS WITH HULL MOUNTED ARRAYS. UNFORTUNATELY, ALONG WITH THE ADVANTAGES OF A TOWED ARRAY COME INHERENT PROBLEMS. THE MAIN PROBLEM IS THAT THE ARRAY CONFIGURATION CHANGES WITH TIM ...
