Abstract :
Analysis using ANSYS CFX software to determine aerodynamic
characteristics. This needs to be paid attention to because it really affects the
performance of the aircraft. In the case of this study, variations in attack angles of
0? and 4?, speeds of 100.584 m/s and 60.96 m/s, and heights of 3048 m and 2438.4
m were used. With a Computational Fluid Dynamic approach using ANSYS-CFX
software. From the results of this analysis, the largest and values are at an
angle of attack of 4?, a speed of 100.584 m/s, and a height of 3048 m with a
value of 1.1586 and 0.0712. Meanwhile, the largest ? value is at an angle
of attack of 0?, speed of 60.96 m/s, and height of 2438.4 m with a value of
21.3813. For the analysis results on variations in angle of attack, the largest
value is at an angle of attack of 16?, the value is 0.6182 at an angle of attack of
24?. For the maximum ? value at an angle of attack of 0? it is 21,263.
