Summary The purpose of this research is to bring rigorous stochastic estimation and control methodologies to impact certain Army' priority technological needs, namely, the task of achieving agile aerodynamic design of helicopter blades, management of supersonic flow past ballistic projectiles and the propagation of blast waves in random environment. The proposed work will be a very novel combination supersonic-transonic aerodynamic design with stochastic analysis and control theory of fluid dynamics, building upon various advances by the principal investigator since the 1980s under DoD sponsorship. The specific mathematical goal will be to perform theoretical and computational study of fully nonlinear hyperbolic and mixed elliptic-hyperbolic type partial differential equations that arise in these contexts subjected to adverse noise and to design feedback controllers for agile performance.
