The effort is primarily to accelerate delivery of an improved stability and transition analysis tool. The initial goal is to aid contractors supported under the DARPA FALCON program in the development and test of Common Aero Vehicle (CAV) maneuvering reentry configurations. Under this effort, state- of-the-art computational tools developed for hypersonic boundary layer stability research will be integrated into a user-friendly package (the Stability and Transition Analysis for Reentry tool, STAR). STAR will be based on Parabolized Stability Equation (PSE) solvers, with additional modules to account for crossflow, transient growth, and roughness effects. Previous flight and ground test data will be analyzed for validation and calibration of the new tool, and stability and transition on actual contractor-provided CAV configurations will be analyzed computationally in concert with ground tests of the same configurations.
