This paper describes the results of a Joint NASA/DoD Scenario-Based Systems Study conducted as part of the DoD Fixed-Wing Vehicle Technology Program. The study investigated both the impact and robustness of specific technology sets to a variety of airlift, bomber, and patrol aircraft concepts. The impacts of these technology sets were developed by measuring the changes in a set of measures of merit, which represented cost vs. capability metrics. The changes in the metrics were then evaluated within the context of a number of future “scenarios” to determine how robust these impacts would be across a variety of possible future conditions. A database was developed which allows the evaluation or ranking of the technology sets from a variety of perspectives.
