Abstract: Because it is multi-objective and multidisciplinary in nature, designing of intake is one of the most demanding tasks. For the first time, this study investigates a design strategy of combining possible multidisciplinary techniques for achieving desirable design of intake with considering both its aerodynamic (AE) and electromagnetic (EM) performances. To facilitate the geometry parameterization, of an intake, Hicks-Henne functions are used as basis functions to formulate the variations of centre line, cross-sectional area and aspect ratio. As an attempt, the gappy proper orthogonal decomposition (POD) method is applied for shape optimization to produce optimal solution in a least square sense. Utilizing this strategy, two redesigned S-shaped intakes are proposed based on a baseline duct. The first one tries to improve only the AE performance of baseline intake, while the second one aims at enhancing both its AE and EM performances. The comparisons between these two redesigned intakes indicated that the result of multidisciplinary design is a compromise solution, due to the conflicting requirements from the viewpoints of AE and EM.
