Abstract In order to improve the test technology and improve the accuracy of the test data under the super large angle of attack, the influence analysis of the model support interference is carried out. Aiming at the support interference problem encountered by the slender configuration in the super large angle of attack test of the high-speed wind tunnel, a numerical simulation method is accepted to study the support interference problem of slender configuration at super large angles of attack in high-speed wind tunnel experiment. The interference of side and segmented support (rear / back support) is analyzed. Numerical results show that, in general, the interference of segmented support is less. Therefore, it's better to use segmented support for static tests. Since the side sting across flow field, additional shock and expansion waves are formed, which significantly change the pressure distribution about the model. When side support is accepted for continuous dynamic experiments at incidence ranging from 0 to 180°, it's necessary to analyze support interference and modify data combined with numerical method.
