In term of active flow control, a bubble-type micro-actuator based on silicone rubber material and its array technology were studied. Firstly, the relationship between micro-bubble membrane deformable height and pressure were analyzed, and the projectiles at empennage in the array were made aerodynamic simulation. The results show that the micro-actuator disturbance flow field boundary layer separates the projectile; the projectile in the micro actuator array arrangement is reasonable, can effectively increase the range and reduce the lateral offset. Therefore, actuation generated by micro actuators on projectile can achieve active control of projectile's flight flow field so as to realize lift eccentricity and other control purposes.
