CREARE WILL DESIGN A COMPLETE EDUCATIONAL DATA ACQUISITION SYSTEM (EDAS) THAT INDCLUDES INSTRUMENTATION, HARDWARE, AND SOFTWARE FOR A SERIES OF EXPERIMENTS TO BE RUN ON MICROCOMPUTERS IN SECONDARY SCHOOL SCIENCE LABORATORIES. IN ITS SIMPLEST FORM, THIS SYSTEM WILL PROVIDE THE TEACHER AND STUDENTS A GENERAL PURPOSE "LINKAGE" BETWEEN PHYSICAL PROCESSES AND A MICROCOMPUTER. HOWEVER, THE SYSTEM WILL A ...

THE MICROGRAVITY ENVIRONMENT OF EARTH ORBIT HAS THE POTENTIAL TO IMPROVE THE QUALITY AND INCREASE THE YIELD OF MATERIALS GROWN BY CHEMICAL VAPOR DEPOSITION (CVD). THE DEVELOPMENT OF CVD IN SPACE WOULD BENEFIT GREATLY FROM THE CAPABILITY TO PREDICT THE IMPORTANT PROCESS HEHAVIOR, ESPECIALLY UNDER THE INFLUENCE OF VARYING GRAVITY FIELDS. THIS CAPABILITY WOULD NOT ONLY FOSTER COMPARISON OF MICROGRAVI ...

TWO-PHASE THERMAL TRANSPORT LOOPS OFFER SIGNIFICANT WEIGHT AND PERFORMANCE ADVANTAGES OVER CONVENTIONAL SINGLE-PHASE SPACECRAFT THERMAL MANAGEMENT SYSTEMS. KEY COMPONENTS IN TWO-PHASE THERMAL MANAGEMENT SYSTEMS ARE THE CONDENSING AND EVAPORATING HEAT EXCHANGERS TO COUPLE THE LOADS TO THE TWO-PHASE THERMAL BUS, AND TO TRANSFER HEAT BETWEEN THE THERMAL BUS AND THE SPACECRAFT RADIATOR. THE MAIN REQUI ...
