A FEASIBILITY STUDY ON THE DEVELOPMENT OF A STOICHIOMETRIC DIESEL ENGINE IS PROPOSED USING THE THERMAL IGNITION COMBUSTION CHAMBER. THE ADIABATIC DIESEL ENGINE WITHOUT WATER OR AIR COOLING ALLOWS THE THERMAL IGNITION CHAMBER TO STORE HEAT DURING COMBUSTION AND RELEASE THE ENERGY FOR IGNITION IN THE FOLLOWING CYCLE. INJECTION OF FUEL ON TO 1800-2000 DEG. F WALL TEMPERATURE WILL PREPARE THE FUEL FOR ...

ISR PROPOSES TO CONDUCT A PROOF-OF-CONCEPT STUDY OF A UNIQUE HIGHFLUX TWO-PHASE THERMAL MANAGEMENT SYSTEM FOR SPACECRAFT. THIS SYSTEM COUPLES HIGH POWER DENSITY EVAPORATIVE SPRAY COOLING WITH AN EXPANDABLE VAPOR STORAGE AND CONDENSATION DEVICE. PREVIOUS WORK HAS DEMONSTRATED THE IMMENSE POTENTIAL OF EVAPORATIVE SPRAY COOLING FOR REMOVING EXTREMELY HIGH HEAT FLUXES (@0 W/CM[2]) WITH VERY SMALL TEMP ...

DEVELOPMENT IS PROPOSED OF AN IMPROVED TYPE OF 400 HZ LINE VOLTAGE REGULATOR (LVR) THAT INHERENTLY PROVIDES LOW-DISTORTION OUTPUT VOLTAGE WITH NON-LINEAR LOADS WITH DISTORTED INPUT VOLTAGE. REGULATION IS ACCOMPLISHED BY ALTERNATELY SWITCHING AT HIGH FREQUENCY A BOOST OR A BUCKTRANSFORMER SECONDARY WINDING IN SERIES BETWEEN THE LVR INPUT AND OUTPUT. THE LVR FUNCTIONS AS A VARIABLE-RATIO TRANSFORMER ...

THE OBJECTIVE OF PHAE I IS TO DETERMINE BY AN ANALYTICAL STUDY THE OPTIMUM DESIGN APPROACH, OR APPROACHES, FOR SOLID-STATE ELECTRICAL FAULT CURRENT LIMITERS FOR THE CURRENT RANGE OF 15 TO 5000 AMPERES. THE ANALYTICAL TRADEOFF STUDY WILL INCLUDE THE FOLLOWING TASKS: 1) DEFINITION OF CURRENT LIMITER REQUIREMENTS, 2) DEFINITION OF TRADEOFF ANALYSIS CRITERIA, 3) DEFINITION OF CANDIDATE CURRENT LIMITER ...

THE PROPOSED RESEARCH PROBLEM IS TO DEVELOP A SENSOR, TOGETHER WITH A MATHEMATICAL ALGORITH, THAT WILL ALLOW THE THREE- DIMENSIONAL QUANTITATIVE EDDY-CURRENT NONDESTRUCTIVE EVALUTION OF MATERIALS AND STRUCTURES. THE APPROACH THAT WE PROPOSE IS BASED ON, AND EXTENDS WORK ON TWO-DIMENSIONAL EDDY-CURRENT NDE THAT THAT HAS ALREADY BEEN PERFORMED BY ANALYTIC, INC. THAT WORK IS BRIEFLY REVIEWED. THE TEC ...

THE PROPOSED RESEARCH PROBLEM IS TO DEVELOP A MODEL AND AN INVERSION ALGORITHM THAT IS SUITABLE FOR THE THREE-DIMENSIONAL QUANTITATIVE NON-DESTRUCTIVE EVALUATION (NDE) OF ADVANCED COMPOSITE MATERIALS BY USING EDDY-CURRENTS. THE APPROACH THAT WE PROPOSE IS BASED ON, AND EXTENDS, WORK THAT HAS ALREADY BEEN PERFORMED BY ANALYTICS, INC. FOR EDDYCURRENT NDE OF CONVENTIAL METALS. THE TECHNICAL OBJECTIVE ...

THIS PROPOSAL IS TO DEMONSTRATE FEASIBILITY OF INSERTION OF SIALIC ACID MOLECULES INTO MEMBRANES OF LIPOSOMES CARRYING HEMOGLOBIN. THE LIPOSOMES MAY BE PROVIDED BY NAVY CONTRACTORS OR PREPARED BY OFFEROR ACCORDING TO CONTRACTORS' SPECIFICATIONS FOR FOMULATION. THE ADDED SIALIC ACID WILL PROTECT THE LIPOSOMES FROM CLEARANCE BY THE RETICULOENDOTHELIAL SYSTEM AND THEREBY INCREASE THE RESIDENCY TIME O ...
