SOLID BORON HAS LONG BEEN RECOGNIZED AS A POTENTIAL HIGH VOLUMETRIC DENSITY PROPELLANT FOR VOLUME LIMITED ROCKET AND AIR BREATHING PROPULSION SYSTEMS. HOWEVER, ACHIEVING THIS POTENTIAL HAS BEEN DIFFICULT DUE TO LOW COMBUSTION AND HEAT RELEASE EFFICIENCIES IN CONVENTIONALLY DESIGNED COMBUSTORS. A THREE PHASE MODEL OF BORON ASSISTED COMBUSTION IS POSTULATED AND THE ROLE THAT KINETIC SENSITIVITY ANAL ...

SEVERAL EXHAUST GAS NO(X) ABATEMENT PROCESSES EXIST BASED ON HETEROGENEOUS REACTION OF A REDUCED NITROGEN CONTAINING ADDITIVES SUCH AS NH(3). NONE OF THESE EXISTING PROCESSES CAN BE USED IN ITS PRESENT FORM TO MEET PROPOSED NO(X) EMISSIONS REGULATIONS ON JET TEST STATIONS AND INCINERATORS. WE PROPOSE TO TEST COMBINATIONS OF ADDITIVES AND CATALYSTS THAT HAVE THE POTENTIAL TO LEAD TO A NEW PROCESS O ...

THE GENERAL PURPOSE ICE DETECTOR/ACCUMULATOR PROPOSED IN THIS DOCUMENT EMPLOYS TWO ULTRASONIC SENSING MODES. RAYLEIGH WAVES (SURFACE WAVES) ARE USED TO DETECT THE ONSET OF ICING, AND TIME-OFFLIGHT MEASUREMENTS IN A NORMAL INCIDENT REFLECTION OF ULTRASONIC PULSES FROM THE ICE LAYERS ARE USED FOR MEASURING APPRECIALBE BUILDUP THICKNESS OF THE ICE (>0.5MM). THE BASIC PRINCIPLES UNDERLYING A TIME-OF-F ...

ACOUSTIC RESONANCE CREATES A PROBLEM WITH BOTH THE OPERATION AND THE DURABILITY OF CURRENT HIGH PERFORMANCE GAS TURBINE AUGMENTORS. FUTURE GAS TURBINES ARE EXPECTED TO HAVE AN EVEN MORE SEVERE ENVIRONMENT FOR AUGMENTOR RESONANCE. THE CURRENT LEVEL OF UNDERSTANDING OF THIS PROBLEM GIVES NO ASSURANCE THAT SATISFACTORY PERFORMANCE CAN BE OBTAINED FROM THE MORE ADVANCED AUGMENTORS WITHOUT MAJOR DEVELO ...

THIS PROJECT WILL CONCEPTUALIZE UNIQUE ADVANCED INFORMATION DISPLAYS TO SUPPORT TACTICAL DECISION MAKING IN A SHIPBOARD ENVIRONMENT, AND DETERMINE THE FEASIBILITY OF IMPLEMENTING THE DISPLAYS IN REAL-TIME USING DATA REPRESENTATIVE OF THAT RESIDENT IN SHIPBOARD DATA BASES AND SENSOR SYSTEMS. COMPUTER PROGRAMS TO IMPLEMENT THE DISPLAY ALGORITHMS WILL BE DESIGNED TO BE COMPATIBLE WITH A STANDARD NAVY ...

THE GOAL OF THIS RESEARCH PROJECT IS TO DEVELOP A PRELIMINARY PROTOTYPE OF A HIERARCHICAL SYSTEM FOR DATA FUSION. THE SYSTEM WILL UTILIZE BOTH THE QUALITATIVE AND JUDGEMENTAL REASONING PROCESS OF A HUMAN EXPERT, AS WELL AS THE QUANTITATIVE CAPABILITIES OF MOST STATISTICAL AND PROBABILISTIC TECHNIQUES. ONE OF THE IMPORTANT AND DIFFICULT TASKS IS TO INTEGRATE CONFLICTING INFORMATION FROM VARIOUS SEN ...
