This paper presents the results of a series of configuration studies conducted in connection with the NASA agility design study project. The purpose of these in-house studies was to develop a parametric data base of configuration concepts and resulting mission performances for a variety of notional fighter/attack missions. This data base will then be used to assess the impact of the imposition of agility requirements on these configurations. Three vehicle concepts were evaluated, and resulting vehicle sizes, weights, and mission performances were compared. Each configuration was then optimized for varying mission requirements and technology levels. It was found that small variations in mission requirements can have significant impact on the design choices. It was also found that optimization of engine cycle variables results in significant improvements in take-off gross weight and vehicle performance regardless of the concept being explored. Finally, results indicate that signature considerations such as internal vs. external weapons carriage can cause dramatic changes in vehicle size, weight, and mission performance.
