Abstract
The primary objective of this study is to design and optimize the wing to improve its aerodynamic performance. Three-dimensional, transient, incompressible, and turbulent flow is considered for simulations. To develop a mechanical model of the wing, this study used a combination of mathematical and numerical modeling techniques. The Navier-Stokes equations with the effects of gravity are applied and the finite-volume method (FVM) is used to solve the problem. This research aims to simulate the dynamics of the wings using dynamic grid methods. Consequently, the wing is allowed to flap and twist at varying angles to determine its aerodynamic parameters. It is postulated that the linear motion of the wing is zero, whereas its angular motion is taken into account. The analysis comprises both the flapping angle, which describes the oscillation, and the twisting angle, which characterizes the twisting motion of the wing. The results show a high degree of agreement with previous work.
