| 摘 要： | 研究了机身头部法向吹气和具有不同指向角的喷管切向吹气对于不同截面的机身前体所产生的影响.在风洞中采用测力的方法给出了不同截面形状的非细长机身的实验结果.讨论了迎角、吹气方式、喷管指向角及截面形状对机身侧力的影响.实验表明,法向吹气和喷管切向吹气都是有效的控制手段,吹气对其中圆锥截面模型的影响最大,椭圆截面模型次之,对带棱截面模型影响最小.

| Abstract: | The aim of this paper is to study the effects of normal and tangential blowing on the side force of forebodies with different cross section.Based on the measurement test of forces in a wind tunnel,the test results were presented.Furthermore,the influence of angle of attack,the blowing means,the pointing angle of tangential blowing and the cross section of the forebodies on the side force were discussed.The results show that,both normal and tangential blowing are effective means of flow control,the influence... |
