![]() In the last section, analyses with high fidelity prediction tools are conducted for the validation of the obtained design and the design method. Then the best performing design in terms of aerodynamics and radar cross section is obtained with an optimization study. In the second section, a design problem is constructed and the verified analyses methods are used for the performance evaluation of the design points required by the surrogate model. Mesh independence and turbulence model selection studies are carried out for the computational fluid dynamics analyses and radar cross section evaluation studies are carried out for the electromagnetic analyses. In the first section, validation studies for the intake performance evaluation methods are conducted. The thesis consists of three main sections. Due to the nature of this multi-objective and multi-disciplinary engineering problem, surrogate based analysis and optimization approach is taken to reduce the computationally expensive and time consuming analyses. To achieve reduced radar signature characteristics, a parameterized double curved intake is proposed. Intakes are key components of aircrafts’ propulsion systems that create open ended cavities resulting in increased radar signature. In this thesis, a design method for a subsonic intake with high aerodynamic performance and reduced radar signature is developed.
