摘要 面向主动流控制研发了基于硅酮橡胶材料的气泡型微致动器及其阵列技术。首先分析了微气泡薄膜变形高度与压力的关系,并对微致动器阵列下的尾翼弹丸进行了空气动力学仿真。结果表明:该微致动器扰动弹丸流场边界层的分离;在弹丸上对微致动器进行合理阵列布置,能够有效增大射程和减小横向偏移。因此,通过微致动器对弹丸的致动作用,可以实现对弹丸飞行流场的有益主动控制,达到增升减偏等控制目的。 In term of active flow control , a bubble-type micro-actuator based on silicone rubber material and its array technology were stud-ied.Firstly, the relationship between micro-bubble membrane deformable height and pressure were analyzed , and the projectiles at empen-nage in the array were made aerodynamic simulation .The results show that the micro-actuator disturbance flow field boundary layer sepa-rates 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 .
