This Standard provides strength and life assessment requirements for National Aeronautics and Space Administration (NASA) liquid-fueled space propulsion system engines. The term "life," as used in this Standard, refers to fatigue and creep. The requirements address analyses and tests to qualify an engine structurally. The total system requirements for engine hot-fire tests are not addressed in these requirements; however, a minimum number of such tests are to be conducted in conjunction with structural analyses and tests to qualify the engine structurally. These requirements define the minimum structural requirements acceptable to NASA. These requirements specify analyses and test factors, margins, and other parameters, where appropriate. In some cases, these requirements are expressed by reference to other Standards.
Keywords
