To provide insulation for tees, elbows, sumps, and valves that are used to pass or store fluids at cryogenic temperatures, individual parts are insulated in an environmentally controlled facility. It is desirable that such insulation be liquid oxygen compatible and be easily removable and reinstallable.
NERVA control drum actuator tests in cryogenic temperature, nuclear radiation, and vacuum environments
Solar absorptance, total hemispherical emittance and absorptance/emittance ratio for metals at cryogenic temperatures measured simultaneously with sinusoidally perturbed incident radiation
Radiation effects on NERVA out-of-core instrumentation, discussing cryogenic temperature measurements and transducer measuring pressure at gamma heating rates
Al alloys sheet, plate and weldments crack behavior and fracture toughness at cryogenic temperatures, using notched and surface flawed plane strain specimens
DC beam experiment for determining molecule sticking coefficients of gas beams incident on Ti, Ba and Sr gettering surfaces at cryogenic temperature
Mechanical stress applied to foam-coated aluminum alloy specimens maintained at cryogenic temperature simulates actual use conditions of the foam insulation. The testing reveals defects in the polyurethane foam or in the foam to metal bond.
Cadmium sulfide photodielectric effect at cryogenic temperatures with bibliography
Leakproof soft metal seal for use in very high vacuum systems operating at cryogenic temperatures
Polyurethane adhesives differential thermal analysis, rebound resilience and tensile properties at cryogenic temperatures
Resilience and tensile properties of polyurethane adhesive at cryogenic temperatures measured by differential thermal analysis
Mechanical properties of new resin at cryogenic temperatures are substantially improved over similar composite structures utilizing conventional resins, while properties at ambient temperature are identical to conventional resin composites.
