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.
