Some seven different configurations of the NSI and other cables were tested in the NASA-MSFC Hot Gas Facility (HGF). The tests were conducted to study what happens to the cables when they are exposed to hot flow as was the case in the first two Shuttle flights, the STS-1 and STSAuthor: Z. S. Karu. In this study, a full annular combustor test rig was used to establish emission levels and combustor performance for comparison with those indicated by the supporting technology program. In addition, a combustor sector test rig was employed to examine differences in emissions and liner temperatures obtained during the full annular performance. Administration (NASA) program requirements for evaluation, testing, and selection of materials to preclude unsafe conditions related to flammability, offgassing, and fluid compatibility. Additional materials performance requirements may be specified in other program or NASA .

During acceptance testing of space telescope antenna pointing system gimbals, the external cover of the heater dislodged during thermal cycling test. The cause was incompatibility of the coefficient of thermal expansion between the cover materials with the housing materials and the fact that the cover and housing were gold plated, which. NASA NID to NPR A. Procedural Effective Date: Ma Requirements Expiration Date: Ma COMPLIANCE IS MANDATORY. RESPONSIBLE OFFICE: Office of the Chief Engineer. NASA Systems Engineering Processes and Requirements. Workmanship Standards. Workmanship is the control of design features, materials and assembly processes to achieve the desired performance and reliability for subassembly interconnections — specifically those in printed wiring assemblies and cable harnesses — and the use of inspection techniques and defect criteria to assure interconnect quality. NSI system control units combine superior performance with field proven reliability to provide complete on-site control and monitoring of central receive systems. They also provide the interface to the NSI MC5 remote control master unit for the control of the central receive antenna, the associated digital receiver and spectrum analyzer as well.
No cryogenic tests were performed which would have revealed the problem. During the Count Down Demonstration Test the oxygen tank could not be emptied by the normal means of pressurized oxygen gas due to a leak at the fill tube. Instead, the tank heaters were . The initiator is electrically actuated by a minimum amps application of all-fire current, producing a hot flame and gas output pressure of to psig within 10 milliseconds in a 10cc closed volume. In addition, the initiator is also designed to meet or exceed the performance requirements of the NASA Standard Initiator. and facilities used during assembly, test, and flight operations. Included are requirements, conditions related to flammability, offgassing, and fluid compatibility. Additional materials performance requirements may be specified in other program or NASA Center-specific documentation. Applicability Materials intended for use in. NASA RELIABILITY PREFERRED PRACTICES FOR DESIGN & TEST. This page features a series of short (4 to 8-page) summaries of reliability design and test practices which have contributed to the success of NASA spaceflight missions. Practices within the categories of natural space environment, reliability design, reliability analysis, and hardware test are provided for viewing and .
