Abstract

This study encompasses the structural analysis of an external aerial pod. The pod's shell constructed from sandwich panel with an arc-tan corrugation. The homogenization technique is employed to find the equivalent effective elastic properties of the pod's sandwich panel structure. Using Euler-Bernoulli beam theory, the sandwich panel structure is mechanically reduced via describing its behavior with five in-plane elastic properties. The energy approach and unit load method are utilized to homogenize the sandwich panel. The model is verified via comparing it against available data in the literature. Also, the validation study conducted on the model shows good agreement with theoretical results. The homogenized model is optimized in which the number of variables in the model is reduced by 50%. In addition, to minimize the drag, a two-dimensional aerodynamics analysis is numerically performed using ANSYS - Fluent to optimize geometrically the designed pod.
