Comparing UAV composite wing stress analysis with one-way and two-way coupled fluid-solid interaction methods

Unmanned aerial vehicle has been extensively used in the military and civil industries these days. Using composites in these structures, due to their high strength-to-weight ratio, is crucial. The optimized design of composite components of the aerial vehicle is important among researchers in these industries. In the present research, an stress analysis of the UAV composite wing was performed with one-way and two-way FSI methods. Stress analysis of a composite wing is performed using the FSI method. The result shows that despite the high precision of the two-way FSI method in comparison with the one-way method, the computational process is time-consuming. So, the one-way FSI method is recommended as a faster method according to the negligible calculated difference between its result in comparison with the two-way method.
