The paper offers design computation method of RSN propulsor fitted with post- swirl stator on AZIPODs. The method implemented as problem solution of non-linear optimization of objective functional with restrictions over the field of infinitely dimensional values (functions being sought for). Numerical solution of this problem is reduced to the finite dimensional problem The shape of internal and external nozzle surface, distribution of pitch, camber, width and thickness of rotor blades and post-swirl stator geometry at radius are unknown functions of RSN propulsor design. Computational accuracy was validated through CFD-aided calculation of designed propulsors. Comparative analysis with model test results was implemented as well. The AZIPOD XL propulsor concept has been developed by the present method.
