In this paper we make an flap actuator by using shape memory effects of SMA spring. We studied that the force and stroke what we need to design and the flap mechanism. The force and stroke was estimated through the analysis program which like a catia, matlab etc. We could design and make flap actuator. So The actuator which used SMA spring can apply to small aircraft.
