翼涡与体涡的相互干扰及其对翼涡破裂的影响

根据流谱观测结果，研究了翼－身组合体和全机的涡系干扰特点，分析了翼涡与体涡的相互诱导，使翼涡与体涡运动发生变化，讨论了影响前缘分离涡破裂的主要因素，并对尾翼的影响、机身后部体涡的强度、非对称体涡出现的条件，以及分离旋涡在稳定发展过程中的抗干扰能力等提出了看法。

Interaction of Wing-Body Vortex System and Influence of Vortex Interaction on Vortex-Burst Location of Leading-Edge-Vortex of Wing

Flow visualisation experiments have been used to study the interaction characteristics of vortices formed from flow separation on the wing-body configuration and wingbody-tail configuration. It has been analyzed that the changes of the movement of wing and body vortices are induced by the interaction of wing and body vortices. Main factors of effects of vortex interaction on the vortex-burst have been discussed. This paper also presents the effects of tail on the vortex interaction, the strength of vortex generated from the rear body, the conditions of the body vortex patterns becoming asymmetry and the ability for the separation vortices in movement to resist disturbance and so on.
