As the newly developing functional material

smart material has become the important material and has the broad application prospects in aerospace engineering. Smart structure is the integration of smart material as actuators and sensors in structural components. The goal of this integration is the creation of a material system having the ability of self-sensing

self-diagnosis

self-actuating and self-healing. Smart structure can adapt to the change of environment and improve the performance of modern aircraft. Smart material and structure has become the research focuses in aerospace field. In this paper

the comprehension review is made of the state of smart material and structural systems. Finally

some existing problems in this field are pointed out and the development trend of smart material and structure in aerospace field is presented.
