The Mechanism of Perturbation-combined Control Technique for Asymmetric Flow over Slender Body at High Attack Angle

摘要：

Based on the study of effect of micro-grain and micro-blowing on asymmetric vortex flow over slender body at high attack angle, a new kind of active control technique named perturbation-combined active control technique was proposed in this paper. It can not only change the sign of side force of slender body arbitrarily, but also can make the magnitude of side force to be variable gradually from zero to maximum. Finally, the mechanism of this new active control technique has also been concluded.
