N2 - To improve aerodynamic performance of propulsion system for stealth aircraft, S-shaped inlet is designed and analyzed. An automated design optimization method was built, based on computational fluid dynamics (CFD), surrogate models and genetic algorithm. Combining parameterized solid model, grid auto-generation, modified Menter's k-ω Shear Stress Transport (SST) turbulent model solver, S-shaped inlet is designed by multi-objective optimization. The optimal recommended configuration is obtained. The aerodynamic performance of optimized inlet is analyzed by Scale Adaptive Simulation (SAS) method on detail and refinement. The results show that SAS method is good at numerical simulation of S-shaped inlet flow. Design optimization can greatly improve the aerodynamic performance of S-shaped inlet. Compared with the original design, the distortion coefficient of optimized inlet is decreased by 16.3% and total pressure recovery factor increased by 1.1% at design point.
