    • A method of controlling an aircraft, missile, munition or ground vehicle with plasma actuators, and more particularly of controlling fluid flow across their surfaces or other surfaces which would benefit from such a method, includes the design of an aerodynamic plasma actuator for the purpose of controlling airflow separation over a control surface of a aircraft, missile, or a ground vehicle, and a method of determining a modulation frequency for the plasma actuator for the purpose of fluid flow control over these vehicles. Various embodiments provide steps to increase the efficiency of aircraft, missiles, munitions and ground vehicles. The method of flow control reduces the power requirements of the aircraft, missile, munition or ground vehicle. These methods also provide alternative aerodynamic control using low-power hingeless plasma actuator devices.
    • 使用等离子体致动器控制飞机,导弹,弹药或地面车辆的方法,更具体地说是控制流过其表面或将受益于这种方法的其它表面的流体流动的方法包括设计空气动力学等离子体致动器,目的在于 控制飞机,导弹或地面车辆的控制表面上的气流分离,以及为了在这些车辆上进行流体流动控制的目的,确定等离子体致动器的调制频率的方法。 各种实施例提供了增加飞机,导弹,弹药和地面车辆的效率的步骤。 流量控制的方法降低了飞机,导弹,弹药或地面车辆的电力需求。 这些方法还提供使用低功率无铰链等离子体致动器装置的替代空气动力学控制。
