N/A

A DESIGN FOR A RUGGED, HIGH-FREQUENCY, ACCELERATION-INSENSITIVE AIRBLAST GAGE IS PROPOSED. THE PROPOSED GAGE SHOULD HAVE ITS FUNDAMENTAL VIBRATION FREQUENCY ABOVE 400 KHZ, BE ROUGHLY CYLINDRICAL IN SHAPE WITH DIAMETER AND LENGTH BOTH LESS THAN ONE INCH, AND HAVE BUILT-IN COMPENSATION WHICH WILL LIMIT SPURIOUS SIGNALS DUE TOACCELERATION TO VERY LOW LEVELS. FULLSCALE OUTPUT FOR AN APPLIED AIRBLAST P ...

HIGHLY ANISOTROPIC ALIGNED UNIAXIAL POLYCRSTALLIVE HEXAGONAL FERRITE COMPOUNDS POSSES BUILT-IN EFFECTIVE MAGNETIC FIELDS. THESE MATERIALS POSSESS ATTRACTIVE MICROWAVE AND MAGNETIC PROPERTIES OF POTENTIAL IMPORTANCE TO ACHIEVE IMPROVED PERFORMANCE IN AND INNOVATIVE STRUCTURES FOR NONRECIPROCAL CIRCUIT FUNCTIONS AT NEAR-MILLIMETER WAVE FREQUENCIES. INVESTIGATIONS WILL BE CONDUCTED FOR THE EVALUATION ...

N/A

INVESTIGATIONS INTO HELICOPTER PILOT FATIGUE REQUIRE THAT EXTERNAL WIND FORCES BE KNOWN IN ORDER TO CORRELATE THE PILOT'S REACTION AND MOTIONS. TO FULLY SEPARATE THE FORCES AND RESPONSES, THE WIND SENSORS MUST HAVE A RESPONSE TIME SHORTER THAN EITHER THE PILOT OR VEHICLE REACTION TIMES. THIS PROPOSAL DESCRIBES AN AIR VELOCITY SENSING TECHNIQUE WHICH DETECTS THE VORTICES THAT ARE SHED FROM A SMALL ...

N/A

IT IS PROPOSED TO UTILIZE A GAS DENSITY DETECTOR FOR PROFILING GASES ENCOUNTERED IN THE HELICOPTER ENVIRONMENT. THE DETECTOR, COUPLED WITH AN APPROPRIATE GAS CHROMATOGRAPH COLUMN, HAS BEEN PROVED IN IDENTIFYING AND QUANTIFYING INDIVIDUAL COMPONENTS IN COMPLEX GAS MIXTURES. THE GAS DENSITY DETECTOR GIVES A RESPONSE THAT IS A FUNCTION OF THE DIFFERENCE IN DENSITY OF THE SELECTED CARRIER GAS AND THE ...

THIS PROPOSED PROGRAM IS TO INVESTIGATE THE FEASIBILITY OF USING UNIQUE FILTERING TECHIQUES TO PROCESS PULSE-TO-PULSE RCS AND PHASE DATA TO TRACK AN AIR VEHICLE IN THE PRESENCE OF CHAFF. THE PROPOSED TECHNIQUE WOULD PERMIT TRACKING THE AIRCRAFT WITH OR WITHOUT THE PRESENCE OF CHAFF. IT IS ANTICIPATED THAT THIS INSTRUMENTATION COULD BE ADDED TO ANY COHERENT OR SEMI-COHERENT RADAR AND BE FAR SUPERIO ...

N/A

AN EVALUATION OF AVAILABLE EXTENDED-WEAR HYDROGEL CONTACT LENS FOR POSSIBLE USE BY MILITARY AIRCREWS UNDER COMBAT CONDITIONS. THIS EVALUATION WILL QUANTITATIVELY AND OVALITATIVELY CHARACTERIZE EACH SUCH LENS AGAINST DOA PROVIDED MILITARY REQUIREMETNS. THE RESULT WILL BE THE SELECTION OF A FAMILY OF LENSES FOR FURTHER CLINICAL AND FIELD INVESTIGATION AND EVALUATION.
