HYPERVELOCITY GUN TECHNOLOGY WILL PLAY A DECISIVE ROLE IN THE FUTURE TACTICAL BATTLEFIELD. WEAPONS WITH MUZZLE VELOCITIES OF 2.5 TO 4KN/S (8,000 TO 12,000 FT/S) OR GREATER HAVE POTENTIAL USES IN ALMOST EVERY ASPECT OF WARFARE. RECENT ADVANCES IN PULSED OWER TECHNOLOGY, SPECIFICALLY THE HIGH ENERGY DENSITIES AVAILABLE WITH INTERGRATED PULSE FORMING NETWORKS (IPFNS) AND ADVANCED ROTATING ELECTRICAL ...

Survival of present day microelectronic circuits depends on their protection from self generated and external electromagnetic interference. This proposal is oriented toward the class of interference generally referred to as overvoltage transients. Means for mitigating these transients include gas discharge tubes, and various solid state devices. Each of these has their own advantages in particu ...

THIS WORK IS TO DEVELOP A METHOD TO IMPROVE THE ABILITY OF THE USNRC TO EVALUATE THE OPERATIONAL SAFETY SIGNIFICANCE OF OCCURANCES AT NUCLEAR POWER PLANTS. PERHAPS THE AREA OF GREATEST SAFETY SIGNIFICANCE IS HUMAN PERFORMANCE, BUT THE TECHNIQUES USED BY NRC DO NOT EVALUATE HUMAN PERFORMANCE IN ANY SYSTEMIC WAY. THE WORK IS PROPOSED TO BE PERFORMED IN THREE STAGES, AND BUILDS ON METHODS THAT HAVE B ...

Pulsed power systems for electric armament and compact weapons require increasingly smaller energy delivery systems and higher levels of reliability and component safety. Although new capacitor technologies such as double layer and electrostatic supercapacitors promise energy densities higher than 10J/cc, liquid impregnated film dielectrics with energy densities of 2.5J/cc, continue to be the sta ...

NSRC PROPOSES AN AMBITIOUS EXPERIMENTAL PROGRAM DESIGNED TO INVESTIGATE FLASHBOARD PLASMA SOURCE IMPROVEMENTS WITH APPLICATION EXISTING OPENING SWITCHES IN DNA SIMULATORS. WE WILL INVESTIGATE POWER SYSTEM OPTIONS INCLUDING DC CHARGING AND EXTERNAL TRIGGER SYSTEMS WITH MODEST TRIGGER REQUIREMENTS. MODIFICATIONS TO THE ELECTRODE GEOMETRY OF THE FLASHBOARDS ARE EXPECTED TO IMPROVE DC HOLD-OFF CAPABIL ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

We propose, in Phase I and Phase II, to build an X-ray simulator capable of easy transportation between sites which can be built for a low cost (

THE DEFENSE NUCLEAR AGENCY (DNA) IS DEVELOPING THE OPERATIONAL MESOSCALE ENVIRONMENT MODEL WITH GRID ADAPTIVITY (OMEGA) TO PREDICT REAL-TIME DISPERSAL OF HAZARDOUS AEROSOLS. ONE REQUIREMENT FOR OMEGA OR ANY SIMILAR MODEL IS TO PREDICT COLLATERAL EFFECTS FROM STRIKES ON NUCLEAR, BIOLOGICAL, AND CHEMICAL (NBC) FACILITIES. THE OBJECTIVE OF THE PROPOSED PHASE I PROGRAM IS TO DETERMINE THE ESSENTIAL FE ...
