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 ...

Two major objectives of the U.S. Army is to increase power density and reduce heat rejection. Reducing airflow requirements of the deisel engine will contribute toward both of these objectives. Reducing air-fuel ratio requirements is one of the major cost effective approaches available for significantly increasing power output and reducing heat rejection in today's power output diesel engine. Po ...

The primary roadblock to the success of the high output Low Heat Rejection (LHR) diesel engine requiring little or no water cooling is the lack of effective liquid lubrication where target top ring reversal (TRR) temperatures between the cylinder liner and piston ring approach 1000 degrees F. Adiabatics, Inc. has developed a Thermo-sealed plasma sprayed Fe2O3 tribological coating which provides e ...

Enterically transmitted pathogens cause far more illness than toxicants such as lead, mercury, pesticides, and all other forms of chemical contamination. The world has become increasingly vulnerable to the spread of old and flew infectious organisms and water-borne pathogens as illustrated by recent outbreaks of 20 well-known and at least 29 previously unknown diseases. New tests are needed to d ...

A Shortfall in marine fisheries production is driving the development of aquaculture technologies on many fronts. Recirculating systems are regarded as critical components of many development schemes. However, interest and use of recirculating systems for production of marine organisms have lagged behind freshwater applications. A floating bead filter which is corrosion resistant (no metal parts), ...

The development of a process for growing single crystal boules of 6H-SiC at the firm has lead to rapid advances in SiC device development and performance including production of the world's only commercially viable blue light emitting diode. Cree is currently using 1.375 inch diameter wafers and is in the process of scaling up to 2 inch production. Cree has also demonstrated a complete range of fi ...

The rapid development of the technology of producing high quality single crystal SiC wafers and thin film presents the opportunity to fabricate solid-state devices with power-temperature capability far greater than devices currently available. This capa- bility is ideally suited for military and commercial applications requiring high blocking voltage switches and amplifiers capable of large curre ...

There is a need for high power solid state devices operating in the millimeter wave frequency range for both radar applications and high frequency communications networks. While GaAs an InP technologies shave demonstrated operation at extremely high frequencies, the power that they can generate is very limited. IN order to replace traveling wave tubes, solid state devices must demonstrate higher ...

The ST-connector is the standard Navy single fiber connector. It is a quick-release fiber connector which makes it easy to connect and install but the quick release nature of the coupling makes it very sensitive to severe vibration. We propose a novel coupling system that will be incorporated into the ST-connector, which will significantly reduce its sensitivity to vibration. Our coupling syst ...

This project involves a feasibility study for a rapid scanning near-infrared/infrared spectrometer for transient, simultaneous measurements of CO2 and H20 concentrations, soot volume fractions and temperatures. Such measurements can lead to improved understanding of the structure of turbulent and laminar flames. A commercial instrument that can reliably provide simultaneous gas concentrtaion, so ...
