In the present work, a convergent-divergent nozzle is aerodynamically designed. The structural loads of the fluid flow nozzle and the temperature of the fluid in it. Initially, the CFD simulation is performed with thermal considerations in the NPR range of the nozzle. Furthermore, the CFD result is used as a load in the nozzle structural analysis. Nozzle is working in the NPR range in its NPR design service. The maximum load on the nozzle structure can occur at any NPR flow value. The problem associated with the design of the nozzle structure is the prediction of the load at various nozzle pressure ratio intervals. It is difficult to find and solve this problem analytically. Experimentation will lead to a more expensive investigation. Therefore, a calculation method is needed to find the load in different NPRs. The maximum load of the CFD simulation is used for structural simulation to complete the nozzle thickness. The interaction of the fluid structure (FSI) is the interaction of some mobile or deformable structures with an internal or surrounding fluid flow. The interaction fluid structure can be stable or oscillatory. The problems of interaction of the fluid structure and the problems of multi physics in general are often too complex to be solved analytically; therefore they must be analyzed by means of experiments or numerical simulations.
