"SSSC is pleased to propose the development and delivery of a Hostile Fire Indication Sensor (HFIS) based on the Phase I design concept. The resulting system will limit the number of circuit card assemblies to two: one for the short wave infrared (SWIR)

THE PROPOSED PROJECT WOULD EVALUATE THE FEASIBILITY OF DEVELOPING A WATER FOG OR SPRAY GENERATOR TO CONTROL ON BOARD AIRCRAFT FIRES BY ATTENUATING RADIATIVE HEAT TRANSFER . INFRARED (IR) RADIATION FROM THE FLAME MAINTAINS COMBUSITION OF THE BURNING SURFACE AND AIDS IN THEINGITION OF COLD SURFACES--THEREBY SPREADING THE FIRE. OPTIMAL USE WILL NEED TO BE MADE OF THE WATER, SINCE IT WILLBE CARRIED ON ...

FEW STUDIES OF AIRCRAFT TRAILING VORTICES HAVE BEEN PERFORM ED IN SHEARED OR STRATIFIED FLOWS. YET, MEASUREMENTS INDICATE THAT THE ATMOSPHERE IS TYPICALLY BOTH SHEARED AND STRATIF IED. THIS LACK OF KNOWLEDGE COULD BE IMPORTANT IF VORTEX EVOLUTION IS SIGNIFICANTLY DIFFERENT IN SHEARED, STRATIFIE D FLOWS THAN IN THE UNSHEARED, UNSTRATIFIED FLOWS THAT HAVE BEEN STUDIED IN THE PAST. OUR RECENT LABORAT ...

A CONSTITUTIVE PACKAGE WILL BE DEVELOPED FOR THE MODELING OFDIRECT CONTACT CONDENSATION IN ADVANCED COMPUTER CODES FOR NUCLEAR REACTOR ANALYSIS. SINCE CURENT APPROACHES ARE BUILT UPON FLOW REGIME MAPS WHICH DO NOT ACCOUNT FOR CON DENSATION EFFECTS, PRESENT ADVANCED THERMAL/HYDRAULIC CODES ARE UNABLE TO MODEL COLD LEG FLOW BEHAVIOR CONSISTENTLY DURING CONDENSATION, ESPECIALLY IF THE FLOW IS OSCILLA ...

HIGH-PRESSURE WATERJET IS ONE OF SEVERAL NEW METHODS FOR CUTTING MATERIALS DEVELOPED DURING THE LAST DECADE. CURRENTLY IT IS USED, AT STATIC WATER PRESSURE UP TO 60,000 PSI, TO CUT A WIDE VARIETY OF SOFT AND MEDIUM-HARD MATERIALS IN FACTORIES; IT HAS BEEN EVALUATED FOR GEOTECHNICAL APPLICATIONS WITH VERY LIMITED SUCCESS. THIS RESEARCH CONCERNS THE USE OF ABRASIVE-ENTRAINED WATERJET FOR CUTTING AND ...

THIS PROGRAM DEALS WITH THE EVALUATION OF LIQUID LEVEL DETECTION DATA OBTAINED DURING THE MT-4 EXPERIMENT, WHICH IS THE LAST TEST PERFORMED IN THE LOCA SIMULATION IN NRU REACTOR PROGRAM. THESE DATA OFFER THE POTENTIAL OR RELATINGTHE ONLY FULL-LENGTH IN REACTOR REFLOOD INFORMATION ON N NUCLEAR-POWERED PWR FUEL BUNDLES TO COLLAPSED LIQUID LEVEL AND TWO-PHASE COOLING OF DEFORMED AND RUPTURED FUEL BUN ...

THIS PROGRAM DEALS WITH USING THE DIGITIZED VIDEO TDR LIQUIDLEVEL DATA PREPARED UNDER CONTRACT (NRC-04-84-146) OF THE MEMT-4 TEST FROM THE LOCA SIMULATION IN NRU PROGRAM. THESE NEW DATA AND TECHNIQUES WILL BE APPLIED TO ESTIMATE THE VOIDFRACTION, LIQUID LEVEL, AND LOCAL HEAT TRANFER CONDITIONS FOR THE OTHER NRU TESTS WHERE ONLY SELF POWERED NEUTRON DETECTORS (SPND'S) AND THERMOCOUPLE DATA ARE AVAI ...
