摘要:

采用测力、测压以及粒子图像测速(PIV)流场测试试验技术,针对细长弹体大攻角时前体非对称涡控制的问题,应用连续有源微吹气与双出口合成射流微吹气手段,对前体非对称涡控制开展了试验研究。试验结果表明:连续有源微吹气控制时,在不同攻角选择适当的吹气流量可以将侧向力控制为零;双出口合成射流微吹气控制时,改变控制电压可以起到侧向力比例控制的效果。流场测试结果显示,弹体产生侧向力时背风涡为非对称结构,合成射流控制具有一定的控制频选特性。低频控制时,涡左右摆动,时均结果为对称分布;高频控制时,左右涡位置稳定,为对称分布。

Abstract:

By measuring force, pressure and particle image velocimetry (PIV) technique, in view of the problem of forebody asymmetric vortex control of slender body at high angle of attack, the test study of the former is carried out by means of continuous active microblowing and double outlet zero mass synthesis of micro jet. The test results show that at different angles of attack, choosing the appropriate flow can eliminate the lateral force to zero; at double outlet of the synthetic jet microblowing control, changings the control voltage can achieve the effect of lateral force proportional control. Field test results show that leeward vortex is a non-symmetric structure when the body has a lateral force, and synthetic jet control has a certain control frequency selection characteristics. Under low frequency control, the vortex swings, and time-averaged result is symmetric distribution; under high frequency control, the position of the left and right vortex is stable and the distribution is symmetrical.

Key words: slender body, microblowing, synthetic jet, forebody vortex control, flow control, control frequency selection characteristics, proportional control
