KINETIC ENERGY PENETRATORS MADE OF DU ALLOYS PERFORM BETTER THAN THE TUNGSTEN HEAVY ALLOYS (WHA). THE IMPROVED PERFORMANCE IN DU ALLOY PENETRATORS IS ATTRIBUTABLE TO FAILURE BY ADIABATIC SHEAR BANDING WHICH HELPS THE PROJECTILE MAINTAIN A SELF-SHARPENED CHISELED NOSE THERBY PENETRATING FURTHER THAN TUNGSTEN BASED PENETRATORS. RADIOLOGICAL HAZARDS OF DU ALLOYS, HOWEVER, DICTATE THE IMPROVEMENT IN P ...

In High Energy Lasers (HEL) a large percentage of the laser energy is wasted typically by switching onto beam dumps. Some of this wasted energy could be utilized to synthesize exotic materials which have useful commercial applications. In order to utilize this wasted energy to synthesize new and exotic materials, specialty chambers and equipment are needed. This program will review previous effort ...

A novel and newly discovered C60 carbon material was found to exhibit unique electrochemical and physical properties. C60 and catalyzed C60 electrodes for hydrogen storage and supplies will be fabricated by vapor deposition and dry pressing. These electrodes will be fully characterized as hydrogen electrodes in C60Hx-air fuel cells. The nature of the electrochemical hydrogenation and dehydrogenati ...

Boron carbide is the preferred ceramic material for armo applications; however, the production costs are very high which can be partially attributed to the high cost consodlidation techniques currently used. A novel fabrication technique is proposed that has very los associated costs and has the potential to produce fully dense B4C. In addition, the process allows for net shape forming so that com ...

There is an acute need for novel broadband filters for unity vision equipment. This need can be satisfied with the recent discovery of a new pure form of carbon - fullerenes. Fullerenes have excellent nonlinear optical properties, show the best boradband limiting performance of all known material sand are extremely effective in the nanosecond pulse regime. This program will develop and demonstrate ...

M-Dot, Inc. ("M-DOT") proposes to design, fabricate and test a thrust augumentation system for low cost expendable turbojet engines. The system will be designed for application on the Sunstrand TJ-90 engine and will utilize existing and proven technologies. The system will consist of the following: 1. Sudden expansion burner for exhaust re-heat. 2. System for water/methanol injection at the compre ...

While computer simulation packages are commonly available, many simulations are still written without the use of existing software. This fact is primarily because current software simulation technology has some serious limitations. For example, current packages rely on cartoon-like, predefined, 2-dimensional graphical representations and are difficult to extend. Further, the packages do not take a ...

OPTICAL FIBERS CAN BE DEVELOPED TO TRANSMIT INTENSE LASER RADIATION THROUGH SELECTIVE CHOICE OF MATERIALS AND DESIGN PARAMETERS FOR THE FIBERS IN THE WAVELENGTH RANGE OF 0.193-10.6 MICRON. THESE FIBERS CAN BE INCORPORATED INTO DELIVERY SYSTEMS FOR PROGRAMMED DELIVERY OF LASER ENERGY AND INTEGRITY VERIFICATION. THE PRESENT PROPOSAL DESCRIBES A PHASE I FEASIBILITY STUDY PROGRAM COMPRISING THE DEVELO ...
