    Abstract: The present invention relates to a missile or aircraft with a hierarchical, modular, closed-loop flow control system and more particularly to aircraft or missile with a flow control system for enhanced aerodynamic control, maneuverability and stabilization and methods of operating the flow control system. Various embodiments of the flow control system of the present invention involve flow sensors, active flow control device or activatable flow effectors and/or logic devices with closed loop control architecture. The sensors are used to estimate or determine flow conditions on surfaces of a missile or aircraft. The active flow control device or activatable flow effectors of these various embodiments create on-demand flow disturbances, preferably micro-disturbances, at different points along various aerodynamic surfaces of the missile or aircraft to achieve a desired stabilization or maneuverability effect. The logic devices are embedded with a hierarchical control structure allowing for rapid, real-time control at the flow surface.

    Abstract: A method and sensor for detecting strain using shape memory alloys is disclosed. The sensor comprises a substrate material, a flexible diaphragm provided on the substrate material and a thin film SMA material deposited on the flexible diaphragm. The thin film SMA material is capable of undergoing a phase transformation in response to a physical stimulus being applied thereto. During such a phase transformation, a change occurs in the electrical resistance of the thin film SMA material. By measuring the value of the electrical resistance of the thin film SMA material immediately before and after the thin film SMA material undergoes a phase transformation, the difference in the value of the electrical resistance can be determined and utilized to determine the magnitude of the physical stimulus that was applied to the thin film SMA material causing it to undergo a phase transformation.
