摘要
通过CFD数值计算分别对某燃气舵推矢装置的稳态气动特性和动态气动特性进行研究和分析,获得该燃气舵在阶跃信号控制下不同舵偏角的稳态气动特性和采用正弦控制规律时的连续动态气动特性,将数值模拟结果与实际地面点火试验结果进行比较,两者吻合较好。
The aerodynamic characteristics of jet vane in steady and dynamic conditions are investi- gated with CFD numerical simulation. The steady aerodynamic characteristics of diversiform rudder angle in step signal control and the continuous dynamic aerodynamic characteristics in the sine control law are obtained. The comparing results show that the numerical simulation results agree well with ground ignition experiments results.
