    Abstract: This research will present numerical model of an aircraft wing to be tested under different types of
loads. Three wings design were tested in this study to show the effect of wing design on the overall vibration
behavior under gust load. The main layout of numerical work is divided into 2 main part: first one is the
modeling of unmanned aircraft wing by using ANSYS environment (APDL) where a 3 dimensional models were
totally simulated within the finite element solver with 3 different internal construction. While the second part
is the performing of load effect on the whole structure of the wing where the simulation was carried out to
guarantee that every point within the simulated structure is subjected to a very similar loading case of during
it actual case. Modal analysis was performed also within the numerical part to investigate the most critical
expected modes of vibrations. This research can be extended to have an experimental part by testing the wings
under gust load within laboratory wind tunnel.
