Application Exploring of Shape Memory Alloy on Fixed Wing Aircraft

Shape memory alloy(SMA)is one kind of material that integrates sensor,driver and actuator.Researchers are trying to apply SMA to fixed wing aircraft to improve performance and reduce jet noise.This paper overviews the principles,structures and control methods of the SMA actuated reconfigurable wing,jet engine inlet,nozzle and jet noise reduction system and some problems of applying SMA to aircraft.It is believed that as more research is to be done,SMA will be applied more to fixed wing aircraft.
