Specific rocket engine hardware and test facility system failures are described which were caused by high pressure liquid and/or gaseous oxygen reactions. The failures were encountered during the development and testing of the space shuttle main engine. Failure mechanisms are discussed as well as corrective actions taken to prevent or reduce the potential of future failures.
Design and test of advanced structural components and assemblies for space shuttle program
The space shuttle, proposed as an earth to orbit reusable vehicle, presents a challenge to materials and design engineers to apply light-weight materials. To provide large payloads, the shuttle structure must be as light weight as possible, yet possess a high degree of structural integrity over a lifetime of multiple flights. This paper reviews the general maturity of advanced composites considered for various components of the shuttle and discusses the range of potential applications for such materials.
Environmental pressure, temperature, and compatibility effects on space shuttle materials
Materials technology for reuse capability of space shuttle, discussing normal and stress corrosion, hydrogen embrittlement and flammability
Several rules to guide choice of materials, and methods of welding, electroplating, and heat treatment will provide a method for minimizing failures in storage tanks and related hardware. Failures are caused by high-pressure hydrogen effects, the formation of hydrides in titanium, and hydrogen absorption through various metals processing techniques.
Hydrogen embrittlement of Saturn launch vehicle hardware components
High pressure storage vessels for gaseous hydrogen, discussing failure, manufacturing controls and access for internal nondestructive inspection
Review of material research at Marshall Space Flight Center
Magnesium-lithium alloy - aluminum plate and casting alloys development and properties
Evaluation tests show that magnesium-lithium alloys are lighter and more ductile than other magnesium alloys. They are being used for packaging, housings, containers, where light weight is more important than strength.
