Study of flow control over different noses with single hole microblowing

摘要

摘要: 在亚临界流动范围内,对具有不同头部形状的尖拱形细长旋成体在无侧滑大迎角下进行单孔位微吹气扰动控制实验.通过对物面压力分布、截面侧向力分布和以前细长旋成体结果的对比和分析,发现单孔位微吹气扰动对于细长旋成体横侧向控制作用在于模型头部背风侧非对称二涡结构对扰动的敏感性.实验分析表明,单孔位微吹气扰动这一大迎角非对称控制手段具有较强的适应能力,其控制能力的大小则由该头部形状的初始状态决定.

Abstract: The SHM(single hole microblowing) as a new perturbation active control technique has been applied to the slender body with different model noses at zero sideslip and high angle of attack. The analyzed and contrasted results of the distribution of the surface pressure distributions and the sectional side forces with the former results of the slender body in the same flow conditions show that the SHM’s control effect to the slender body is due to that the two asymmetric vortices over the slender body model are sensitive to the nose perturbations. The analyses indicate that the SHM’s control ability has strong adaptability to various slender body at high angles of attack, and its control ability is determined by the original state of the flowfield around the slender body.
