ABSTRACT: The purpose of this study is to identify test requirements for a national maglev development program. This interim report is submitted in accordance with the Maglev Test Plan Contract DTFR53-91-C-00071 and includes the following: conclusion of a literature search in which 160 citations were reviewed for relevancy; interview results from 31 industry experts; identification of 94 distinct program development risks; characterization of risk by subsystem, severity, type, mitigation method; and recommendation for scheduling risk mitigation activities into 5 development phases consistent with the Intermodal Surface Transportation Efficiency Act of 1991. A Test Requirements Analysis Team, comprised of contractor personnel, successfully executed a process to identify, document, and analyze the following maglev system aspects: architecture; operational concepts; leading maglev system developers; test planning and facilities exercised in prior related activities; and development risk. Analysis within this report substantiates a notion that dynamics, reliability, maintainability, and availability risks dominate the maglev program not only in total number of risks but in risk severity as well. Aging and electromagnetic field risks are also numerous and severe. Control, cryogenics and emergency, although few in total number of risks, are high severity and warrant close attention in the development program. These 7 risk types constitute 41 of the 94 total risks (24 of which are high severity). Collectively, they suggest the need for a carefully crafted and intensive mitigation plan, executed early in the program, in which analysis and high-fidelity testing is performed at a scale commensurate with the risk. An additional 52 risks are characterized into 13 types that are generally less severe. With the conclusion of the literature search and risk characterization phase of the study, activity has turned to test planning and facilities utilization strategies, the results of which will be presented in a final report.
