In order to optimize the design of strut in the integrated afterburner, the rectification characteristics of the strut under the non-uniform inlet of strong cosine rotation were investigated. Different structures of cosine rotation generator were designed to reproduce the non-uniform inlet of strong cosine rotation. The rectification effects of different struts and their flow loss were analyzed. The results showed that the generators could reproduce the non-uniform inlet of strong cosine rotation; the designed strut had the best rectification effect when its bending angle matched the cosine rotation angle of inlet; the mismatching of angle led to the worse rectification effect, especially in terms of non-uniform Mach number; the flow loss of strut increased with the increase of Mach number of inlet, the flow loss of strut with best rectification increased slowly with Mach number, which was within 2.6%.
