WebThe 12° corrugated angle is incorporated in the new modified design with varying pitch length, corrugated angle and peak height to achieve the higher lift to drag ratio. The simulation is carried out using Ansys CFD as a simulation tool and ICEM CFD as a modeling tool for 2-D corrugated airfoil. WebTherefore, the attitude of the corrugated airfoil is also changed for the elastic wings due to the hydrodynamic moment on the corrugated airfoil. Then, the lift and drag of the elastic wings are changed compared with that of the rigid wings due to the deformation wings (in terms of changing the attitude of the corrugated airfoils). However ...
