An entropy-production-based loss decomposition framework is used to quantify curvature-induced loss on a 2D wide-range speed aircraft profile. Varying the afterbody radius leaves the loss pattern largely unchanged but alters entropy-production intensity and integrated afterbody loss. The findings highlight unresolved afterbody loss mechanisms for further study.
