ADIABATICS, INC. IS PLEASED TO PROPOSE A RESEARCH PROGRAM TO DESIGN AN OPTIMUM PISTON FOR A HIGH TEMPERATURE MILITARY ENGINE. ADIABATICS, INC. HAS BEEN CONDUCTING A PROGRAM FOR TACOM TITLED "DEVELOPMENT OF TRIBOLOGICAL SYSTEMS AND ADVANCED HIGH TEMPERATURE IN-CYLINDER COMPONENTS FOR ADVANCED HIGH TEMPERATURE DIESEL ENGINES" FOR THE PAST FIVE YEARS. BASED ON OUR EXPERIENCE WITH DESIGNING COMPONENTS ...

CURRENTLY, AIRBREATHING PROPULSION SYSTEMS WHICH OPERATE IN THE HIGH SUBSONIC REGIME ARE EXPENSIVE, COMPLEX, HEAVY AND USE PERISHABLE FUELS. TO OVERCOME THESE LIMITATIONS, A NOVEL PROPULSION CONCEPT BASED ON A PULSE DETONATION ENGINE (PDE) OR A CONVENTIONAL RAMJET COMBUSTOR (CRC) COUPLED WITH A BORON SOLID FUELED HYBRID GAS GENERATOR (HGG) IS PROPOSED. THE INNOVATION DRAWS FROM RECENT SUCCESSES IN ...

Increasing Navy use of embedded computer systems results in stringent requirements for real-time performance, reliability, and cost. Computer systems are critical embedded components of Naval warfare systems. The demands on embedded computer systems are increasing in terms of information processing and storage/retrieval. The designer must analyze results across many dimensions to identify critical ...

RECENT DEVELOPMENTS IN INTERNATIONAL RELATIONS HAVE LED TO THE NECESSITY FOR BATTLE READINESS IN A REGION WHERE CHEMICAL OR BIOLOGICAL WARFARE AGENTS HAVE BEEN EMPLOYED IN THE PAST. AT PRESENT, LITTLE ATTENTION HAS BEEN PAID TO METHODS FOR IDENTIFYING THE CHEMICAL OR BIOLOGICAL CONDITIONS OF FREE STANDING STRUCTURES. THIS PROPOSAL SUGGESTS THE DEVELOPMENT OF OPTICAL SENSORS BASED ON THE INTERACTIO ...

Measuring light transmission through sea ice in artic regions is important to the understanding of the biological potential, the regional heat and mass balance, and for the investigation of possible through-ice communications. Past measurements have been made with a submersible scanning spectroradiometer. In this study a design will be developed for a two-spectrometer instrument to measure simulta ...

THE IUSS HAS AN URGENT NEED FOR MORE EFFICIENT METHODS OF SIGNAL PROCSSSING. TO MEET THIS END, SUBMARINE DETECTION AND CLASSIFICATION SYSTEMS MUST BE REEXAMINED AND MODIFIED. THIS PROPOSAL EXAMINES THE POTENTIAL OF AN INNOVATIVE TECHNIQUE CALLED FRACTAL IMAGE ANALYSIS TOAID OPERATORS TO ACCURATELY AND EFFICIENTLY DETECT AND CLASSIFY SUBMARINES IN A PASSIVE SONAR ENVIRONMENT. FRACTAL IMAGE ANALYSIS ...

There are no commercial amplifiers that can operate at temperatures above 125 degrees Celsius. We will combine two comparable wide bandgap semiconducting materials to make electronic amplifiers and switches that operate at high temperatures (at least 500 degrees Celsius). These devices can be controlled remotely by a light beam. Hence wireless coupling to a room temperature macroprocessor is possi ...

A NOVEL APPROACH TO LOW COST SHAPED BEAM SCANNING FOR MONOLITHIC STRUCTURES IS PROPOSED. THE TECHNIQUE MAKE USE OF RADOME MATERIAL COSTING OF THE CONVENTIONAL MONOLITHIC STRUCTURE; THE RADOME ITSELF IS COMPOSED OF A COMPOSITE OF HIGH DIELECTRIC CONSTANT/MAGNETICALLY SENSITIVE MATERIAL-REFERED TO AS "DIELECTROMAGNETIC" (DEM) MATERIAL. THE DEM MATERIAL CHARACTERISTICS ARE DESIGNED TO PROVIDE A SHAPE ...

Due to the limited space and the need for flush mounting charactistics, a new and novel series of antenna systems for communications and ECM is proposed. It is proposed to use dielectromagnetic (DM) materials to miniaturize antennas and for RF DM lens to focus the RF signals into the below the surface antennas. An Astron pioneered subminiature direction finding system using DM materials, will be m ...

Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transmitted or received, i.e. one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency nulls begin to develop which threaten the integrity of the communication link. Experience has shown that small excursion ...
