SRB frustrum 'smiley' cracking phenomenon study [PDF]

The thermal protection system installed on the SRB frustrums incurs the formation of debonds between the MSA-2 TPS material and the substrate. The debonds can lead to surface penetrating cracks, called 'smileys' near sealed fasteners and other surface ...

Computational fluid dynamics simulations of spray tests in a multicompartment construction with an Eulerian–Lagrangian approach

Frontiers in Energy Research
This paper is an investigation of the gas mixing and depressurization effects of containment spray on hydrogen risk during a typical severe accident in a light water reactor (LWR).

Contributions of Microgravity Test Results to the Design of Spacecraft Fire Safety Systems [PDF]

Experiments conducted in spacecraft and drop towers show that thin-sheet materials have reduced flammability ranges and flame-spread rates under quiescent low-gravity environments (microgravity) as compared to normal gravity.

Self-powered mixer for pressurized containers [PDF]

, 1973
Mechanical stirrer, installed entirely within tank, is powered by turbine driven by discharge flow of fluid. Contents of tank are automatically mixed whenever fluid in tank is discharged.

Alternative Refrigerants in Adiabatic Capillary Tubes [PDF]

, 1996
This study examines the mass flow rate of refrigerants in adiabatic capillary tubes, with an emphasis on the nature of the metastable region for both single component refrigerants and mixtures. The metastable region of a capillary tube was found to be

A 99 percent purity molecular sieve oxygen generator [PDF]

Molecular sieve oxygen generating systems (MSOGS) have become the accepted method for the production of breathable oxygen on military aircraft. These systems separate oxygen for aircraft engine bleed air by application of pressure swing adsorption (PSA ...

The performance of multilayer insulation in a rapidly depressurizing environment [PDF]

The performance of multilayer insulation in a rapidly depressurizing environment is determined by the variation of heat transfer with internal pressure and the pressure history of the interstitial gas.

Apollo portable life support system performance report [PDF]

The performance of the Apollo portable life support system (PLSS) on actual lunar missions is discussed. Both subjective comments by the crewmen and recorded telemetry data are evaluated although emphasis is on the telemetry data.
