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 ...

LASER ROCKET PROPULSION RESEARCH RECENTLY HAS DEMONSTRATED SUBSTANTIALPOTENTIAL FOR THE CONVERSION OF HIGH POWER LASER ENERGY INTO THERMAL PROPULSIVE ENERGY, USING EITHER CONTINUOUS OR PULSED MODE LASER SOURCES. IT IS NOW POSSIBLE FOR THE FIRST TIME TO DEVELOP PROTOTYPE DESIGNS FOR ACTUAL LASER PROPULSION THRUSTERS THAT CAN BE BUILT AND TESTED AT REALISTIC LASER POWERS. TO ACCOMPLISH THIS, PREVIOU ...

FOR A CONE-SHAPED REENTRY VEHICLE, THE ANTENNA WINDOWS CAN BE THE NUMBER ONE CONTRIBUTOR TO THE VEHICLE'S RADAR SIGNATURE AT CERTAIN RESONNANCE FREQUENCIES. WE PROPOSE TO DEVELOP A COMPUTER MODEL FOR PREDICTING THE RADAR-CROSS-SECTION (RCS) OF THE ANTENNA WINDOW BASED ON AN EXACT MODE MATCHING TECHNIQUE IN ELECTROMAGNETIC THEORY. IN PHASE II, THIS CODE IS TO BE EXPANDED SO THAT THE RCS OF THE ENTI ...

THE IMPROVEMENT OF SINGLE CRYSTAL DIAMOND TOOLS VIA THE INVESTIGATION OF DESIGN ALTERNATIVES TO EXISTING EDGE TECHNOLOGIES EQUIPMENT TO IMPROVE ROUNDNESS OF TOOL NOSE RADIUS AND DETERMINATION OF OPTIMUM DIAMOND CRYSTAL ORIENTATION, EDGE PREPARATION AND TITANIUM NITRIDE COATINGS TO IMPROVE TOOL EDGE DURABILITY WHEN MACHINING HIGH PHOSPHOROUS ELECTROLESS NICKEL MATERIALS.

IN VERY DENSE ELECTROMAGNETIC SIGNAL ENVIRONMENTS, A FAST ANALOG PREPROCESSOR MAY BE OF SIGNIFICANT VALUE IN REDUCING THE BURDEN OF A/D CONVERTERS AND DIGITAL PROCESSORS AND MAY SUBSTANTIALLY REDUCE RESPONSE TIME IN EW SYSTEMS. THIS PROPOSAL SEEKS TO DESIGN AND EVALUATE AN ANALOG PATTERN-MATCHING SYSTEM BASED ON THE EMERGING TECHNOLOGY OF ACOUSTIC CHARGE TRANSPORT (ACT). THIS SYSTEM MAY BE USED TO ...

RESEARCH WILL BE DIRECTED TOWARDS CHARACTERIZING AN ADVANCED BIOSENSOR TECHNOLOGY COMPATIBLE FOR THE REAL-TIME INDIRECT OPTICAL DETECTION OF AMINO ACIDS AS TYPIFIED BY L-PHENYLALANINE, L-DOPA, L-TRYPTOPHAN AND RELATED COMPOUNDS. THE TECHNICAL STRATEGY WILL INVOLVE THE INDIRECT OPTICAL DETECTION OF AMINES AND AMINO ACIDS BY MONITORING CHANGES INDUCED IN THE VISIBLE SPECTRA OF IMMOBILIZED CHROMAGENI ...

THE PROJECT WILL DEVELOP AND TEST A HARDENED GUNN VOLTAGE CONTROLLED OSCILLATOR (VCO) CAPABLE OF SURVIVAL TO A LEVEL OF AT LEAST 50,000 G WITH A GOAL OF 100,000 G. SUCH AN OSCILLATOR HAS POTENTIAL APPLICATIONS TO PROJECTILES OR MISSILES WHICH EXPERIENCE VERY HIGH SHOCK DURING FIRING (LAUNCH). THE DESIGN INVOLVES USE OF A RIGID CHOKE STRUCTURE WHICH PREVENTS TOP LOADING ON THE GUNN AND VARACTOR DIO ...
