Abstract
Research and development of smart materials and smarth structural systems has been actively pursued during the last decade. Smarh materials are defined as materials that can adapt to external stimuli, such as load or environment. The control capabilities of the material can be enhanced by material composition, processing, defect or microstructure, and conditioning to adapt to various levels of stimuli. When these special types of materials are integrated into the structure, both the sensing and the actuating mechanisms become integral parts of the structure through induced strain actuation. The technological applications of this class of materials span a wide range. Today a large variety of materials and techniques exist: piezoceramics, magnetostrictives, electrostrictives, electrorheological fluids, shape-memory alloys and fiber optics that serve as sensors and actuators in smarth structures. An intelligent or smart structure is generaly considerd an integrated system of structure, sensors, actuators, and a control module. Currently there is a great deal of interest in applying smart structure tehnology to various physical systems such as active vibration, noise, aeroelastic stability, damping, shape contol, structure health monitoring, process monitoring and demage and delamination detection. A significant amount of the early development was devoted to application to space-related systems. Recently, studies have also been conducted to investigate using this concept to improve fixed wing performance. During the laste decade, significant research efforts have also been directed toward applying these concepts to rotary wing aircraft. In our research the intelligent materials will be used for aircraft propellers and wind turbines. The improvement of such propellers and wind turbines will be better efficiency and low noise, that mean more environment friendly.
