N/A

OPTICAL COMMUNICATION LINKS HAVE SEVERAL ADVANTAGES FOR SHIP-TO-SHIP APPLICATIONS. KEY FEATURES WHICH MAKE OPTICAL COMMUNICATION ATTRACTIVE INCLUDE HIGH DATA BANDWIDTH AND EASE OF PROTECTION FROM INTERCEPTION. THE PERFORMANCE REQUIREMENTS FOR POINTING AND TRACKING SYSTEMS FOR OPTICAL COMMUNICATION LINKS ARE DEMANDING WHEN EITHER TRANSMITTER OR RECEIVER IS ON A MOVING VEHICLE. CONSEQUENTLY, SUCH SY ...

THE INTENT OF THIS WORK IS TO DEVELOP AN ADVANCED ESTIMATION ALGORITHM FOR MANEUVERING TARGET STATE ESTIMATION AND PREDICTION. THE ALGORITHM WILL BE USED FOR FIRE CONTROL IN THE LOCAL AREA DEFENSE ROLE. THE TARGET STATE ESTIMATOR USES TWO DIMENSIONAL INFRA-RED ELECTRO-OPTICAL IMAGERY AND RADAR DATA TO COMPUTE CURRENT AND PREDICT FUTURE TARGET STATES. INCLUDED IN THIS ANALYSIS WILL BE ALGORITHMS FO ...

N/A

THE LANDING OF AIRCRAFT ABOARD CARRIERS AT SEA IS ONE OF THE MOST DANGEROUS OF MILITARY OPERATIONS. THE DANGER IS COMPOUND MANY-FOLD WHEN RECOVERIES ARE CARRIED OUT AT NIGHT DURING EMCON CONDITIONS. WITHOUT THE SHIP'S RADAR OR FREE RADIO COMMUNICATION WITH PILOTS, A SHIP-BASED SENSOR IS REQUIRED THAT CAN GIVE GLIDE SLOPE INFORMATION TO THE LSO AS WELL AS ALLOW VERIFICATION OF AIRCRAFT TYPE AND LAN ...

N/A

THE NEED FOR LARGE, HIGH-PERFORMANCE ARRAYS ON NONPLANAR SURFACES, COUPLED WITH RECENT ADVANCES IN ELECTRONICS TECHNOLOGY, HAS RESULTED IN A RECENT SURGE OF INTEREST IN CONFORMAL ARRAYS. APPLICATIONS INCLUDE LARGE CONFORMAL ARRAYS ON AIRCRAFT FUSELAGE FOR SURVEILLANCE, ON ARTILLERY SHELLS, FOR MISSILE SEEKERS (AIR-TO-AIR, AND AIR-TOSURFACE APPLICATIONS) AND ON REENTRY VEHICLES. CONFORMAL ARRAYS HA ...

THERE IS NEED FOR A COMPACT UNDERWATER BUOYANCY SYSTEM CAPABLE OF MAINTAINING A SPECIFIED (ABOUT 10 LB) WEIGHT AT ANY PRESET WATER DEPTH FROM 0 TO 2,000 FT. IT WOULD BE USED IN EXPENDABLE SONOBUOYS WHERE HYDROPHONES OR TRANSDUCERS MUST BE KEPT AT A PRESET DEPTH. DEFENSE SYSTEMS INC. (DSI) PROPOSES TO BUILD AND DEMONSTRATE IN PHASE I SUCH A DEVICE IN THE FORM OF AN EXPANDING, NESTED SET OF 6" DIAME ...

CURRENT SHIPBOARD AIRCRAFT SUPPORT EQUIPMENT HAS INADEQUATE CAPABILITY TO RESIST EXPECTED SHOCK LEVELS IN HEAVY WEATHER AND COMBAT OPERATIONS. CAREFUL REVIEW OF THE STATE-OF-THE-ART INDICATES THAT MANY CURRENTLY USED PROCEDURES FOR SHOCK RESPONSE PREDICTION OF SHIPBOARD EQUIPMENT AND FOR SHIP GIRDER RESPONSE TO SHOCK LOADS ARE INADEQUATE BECAUSE OF THE MANY ASSUMPTIONS AND THE OVERSIMPLIFIED MODEL ...

THIS PROPOSAL IS FOR A DESIGN STUDY FOR THE DEVELOPMENT OF A COMPUTER CODE FOR THREE DIMENSIONAL TRANSIENT FLOW PREDICTION. THE COMPUTER CODE WILL BE CAPABLE OF ACCURATELY PREDICTING INCOMPRESSIBLE TRANSIENT TURBULENT FLOW FIELDS USING THE FINITE VOLUME TECHNIQUE. THE CODE WILL BE APPLICABLE TO THREE DIMENSIONAL INTERNAL AND EXTERNAL FLOW PROBLEMS AND WILL BE IN THE FORM OF GENERALIZED CURVILINEAR ...
