Effect of Delta Wing Shape on Aerodynamic Characteristics at Low Speed
Main Article Content
Abstract
The paper concentrated on effect of sweep angle of delta wing at very low speed of 5 m/s and attack angle of 20 degrees. Sweep angle changed inducing a change of shape of delta wing. Aerodynamic characteristics of delta wing were estimated by changing sweep angles (32, 45, and 60 degrees) within attack angle of 20 degrees and air velocity of 5 m/s. Firstly, experimental configuration was conducted to validate numerical results solving with help of ANSYS software. Results showed a good agreement between numerical and experimental method. Then, simulation method was used to carry out effect of delta wing shape on aerodynamic characteristics at low speed. From obtained results, it was remarked that, increasing sweep angle of delta wing from 32 to 60 degrees made reduce drag and lift forces. Aerodynamic quality of delta wing with high sweep angle was higher than that of a delta wing with small sweep angle.
