研究了利用合成射流作动器进行射流矢量控制的机理。初级射流的最终偏转角是由三个不同区域的合成射流控制初级射流的结果。合成射流诱导主射流出口附近较低的静压、合成射流在吹吸行程中对主射流流体的夹带和吸收、合成射流旋涡与主射流剪切层之间的耦合和相互作用是合成射流致动器矢量化主射流的主要控制机理。分析总结了影响射流矢量化的主要因素，提出了利用合成射流作动器进行射流矢量化的预备模型。
The control mechanism of jet vectoring using synthetic jet actuators is investigated. The final deflection angle of the primary jet is a result of the primary jet controlled by synthetic jets at three different regions. The lower static pressure near the primary jet exit induced by the synthetic jet, the entrainment and absorption of the primary jet fluid by the synthetic jet during the blowing and the suction stroke, the coupling and interaction between the vortices of synthetic jet and the shear layer of the primary jet are the main control mechanisms for the synthetic jet actuator vectoring a primary jet. The main factors influencing jet vectoring are analyzed and summarized, and a preparatory model for jet vectoring using synthetic jet actuator is presented.
